true dual setup

Sure someone has asked b4 but here goes....Just got some Offroad Pacesetter LT's and was wondering what true-dual set-up i should go with. i wanna delete the cats also and want a loud set-up as I dont have any emmisions in florida, but i do like seeing the exhaust out the back so dont want to do dumps...what do you guys think?

y pipes are for cat-back cars

u need either an x-pipe or h-pipe for duals

Run the summit universal x-pipe kit with some edelbrock SDT mufflers

knew that, meant H, think i would rather go X-pipe though anyways, just looks like it would flow better...never seen the SDT mufflers, will check them out, thanks

x pipe and dynomax bullets. you still have gc and it sounds great. you go with a regular type muffler and you'll scrape off your exhaust.

magnaflow 4x9 mufflers are the same diameter as bullets...they tuck up well for being full size mufflers.

but running the exhaust out the back will take $$$$

easiest way is 2.5" pipes, side by side...then routed over the axle in the stock location. you'll probably have to install the BMR panhard bar kit to allow room.

do you have dumps or do you run them all the way to the rear? I have heard ppl say that dumping them before the rear-axle actually allows you to gain some HP...Also, i know it would prob be cheaper to wait for some used but do you know where i can pick up those bullets cheapest?

Yeah, hopefully i have someone who will be helping me do the exhaust to save me some money, then ill just go get it welded at a shop. But i was planning on getting the adjustable panhard bar kit anyways so that would prob work out. Will i have to get the panhard bar for sure, too be able to have the rear-exit

sorry...was not clear on that.

you'll need the panhard bar relocation kit to allow the clearance. it is a separate piece from the actual panhard bar.

i doubt there is much hp gain/lost between dumping before the axle compared to after. i suppose there is a small amount of increased resistence from the bends that go over the axle. but as long as they are mandrel bent...it should be extremely minimal.

and new bullets are about $30-40...depending on lenght...doubt you'd gain much from finding them used. look in jegs or summit, they have some that are 24" and still cheap...gives you a bit mroe sound control over the 16-18" bullets.

what he said^^^ and you can get more ground clearance out of the bullets if you make an indention for them, it ends up in the corners of the rear seats. other mufflers you can't do this because they are not cylender style they are rectangle. i can't spell for crap.

ohhh, that is different,lol...so will i need this relocation bracket and the actual panhard bar then, or can i use this with the stock panhard bar

the SDTs are the thinnest mufflers at i think 3 5/8"
I think bullets are 4" or so for the 3" mufflers

So this is the pretty much your exact setup...did u delete the cats? second, did u buy the 02 extensions instead of wiring the ones pacesetter sends, if so what length 02's, 12in or 24in.? Lastly, got any pics of your setup, would like to see how it looked when finished, especially where the indentation for the bullets is in the corner of the rear seats..

by the way, thanks a lot to everyone for all the helpful ideas so far

i have pacesetter coated long tubes, into a reducer 3 inch to 2 1/2, into a x pipe, into dynomax bullet mufflers.

no cats, i used the wireing that pacesetter sends, but i am an electrician so i know for sure that my connections were perfect and that it was all done right. i also have a tool thats made specifically for crimping that does better than anything you could come up with.

i will probably be able to get pictures tomarrow, its raining right now and i think it will clear up thursday.

sounds good. would love to see the setup before i do it. So, i will also need the reducer...what if i wanted to run 3in. piping after the bullets, should i not do that (will they fit), or should I run the 2.5in piping. Curious because if the 3in. would work, wouldnt i have to get another reducer for the other side of the bullets...sounds like a lot more $$ tho

solder the wires on ur o2 extensions, and u will never have problems with them being loose or giving bad signals

you can run 3 inch piping and 3 inch bullet mufflers but you will lose a little torque. also you will cut your ground clearance. 3 inch is overkill, and more expensive. look in the fact section for hp and piping recomendations, you will see that 2 * 2 1/2 is more than enough.

oh and the bullets come in 2 1/2 in and out i think that is what you were asking about?

Wow, didnt realize that 2.5in. piping could handle that much power!

Ok, so i should get the 4" bullet mufflers with 2 1/2in. in & out, then just do 2 1/2in. piping all the way back. And i noticed that that size bullet is 16.5in in length, that the right one? Also, Since the pipe and muffler out will be the same size do they just get welded together?

Lastly, do i run a reducer from the actual LT's to the muffler?

thanks for the tip...prob gonna have to get one to do it, either that or just buy the extensions, which ever is cheaper

i'll get you some pics tomarrow, yes that is the right muffler size

ok, seeing as im a pretty visual person it will prob, make it much easier:)

"so will i need this relocation bracket and the actual panhard bar then, or can i use this with the stock panhard bar"

only thing the panhard bar does is locate the axle side to side nothing to do with exhaust...the relocation bracket is designed to give the proper room to run bigger exhaust over the axle. so you can run the stock panhard with the relocation bracket to allow for clearance.

to run a 2.5" setup...you put the reducer right off the headers

there are other mufflers identical to the ones you list as 16" long...someone makes some that are 23-24"...check out summit or jegs. cost is minimal and you'll get a little more noise control.

dual 2.5" pipes has similar flow capacity as a single 3.5" pipe


"sounds good. would love to see the setup before i do it. So, i will also need the reducer...what if i wanted to run 3in. piping after the bullets, should i not do that (will they fit), or should I run the 2.5in piping"

why would you run 2.5" pipe to the muffler, then 3" out the back?? there is nothing to be gained from that.
3" is possible out the rear...BMR claims thier bracket makes enough room. but for the added hassle...not really worth it.

as for welding or not...it's your choice. the slip fits should allow you to clamp or weld.
most likely you'll need to do some welding...since nobody really makes a true-dual kit that goes over the axle for the Fbody...so it's all gonna be custom anyway

Thankss! That clears a lot of things up. I will just do the 2.5" piping all the way.

So when you say that the longer muffler will give me more noise control, are you saying that the 16.5" Dynomax bullet will be Extremely loud!? I mean, i want it to definently be louder than it is now, but i do have to make long road trips home and will prob want to hear the radio at some point in time;) . Plus the only other one i see in my price range is the Moroso spiral flow muffler which is 18" long overall. All the other bullet type mufflers are around $120+ each while dynomax and moroso are only around $40 each....

Lastly, where do i get that panhard relocation kit?

how loud is too loud is totally subjective.

the bullets tend do be pretty loud, although running them out the back will DEFINATLY help!!

i looked up the longer muffler:

summit brand glasspack mufflers: pn sum-630815 $25

ran one on my LS1 for a while as a loudmouth style setup w/ single 3" pipe. sounded decent, but just a little raspy. i think running 2 of these and out the back would sound pretty good.


as for the phb kit...order directly from BMR www.bmrfabrication.com

or see if you can get in on a group purchase someplace...do a search.

thats a myspace vid link to my car with mods in sig. yours would sound very simular minus the slipping transmission.

ive got lanes true duals and love them

Never heard of them, got a link for them or any links?

hey man its snowing now no pictures sorry.

hey man its snowing now no pictures sorry.

damn! Its raining like CRAZY here but think the snow might be jus a lil worse...no prob man, even tho im collecting everything i need for the build now, im not going to install for another 3 weeks

Also, the exhuast sounds good, but its hard to tell the diff b/w exhaust sounds on video clips, did u have the window down?

holy sh$T, that PHB relocation kit goes for $230, anyone know or have one i could get cheaper, and this is a MUST have for going true dual out the rear right?

Never heard of them, got a link for them or any links?

I cant seem to find the website anymore? Maybe they went out of business...i will post pics in the next couple days

alright, and i meant to say, "got a link for them or any pics"

you MIGHT be able to fit dual 2.5" pipes over the axle without using the kit.

hard to say without trying.

but it kindda comes with the territory...duals out the back is difficult and $$$$...otherwise everyone would have it...hell...GM would have done it.

you're gonna be spending a couple hundred on pipes anyway...not to mention the mufflers, hangers and tips...i guess what's another $230??

unless you can get in on a group purchase or sale...you won't beat that price

they are both up.

on stock manifolds you will spend a total of 210 for 2.5 true duals x pipe and 2 dynomax bullets dumped, this is what i spent total, including installation and fab work.

if you really want it out the back look into getting the stock piping that goes over the rear axle, then you will have 2 that were specifically made to go over it.

not mine but heres the concept:

Here's a few pics of mine, made with a Jegs 2.5" universal kit and a 3" X-pipe kit...reduces down to 2.5" just after the X-pipe and Dynatech Split flow straight thru muffs.

My setup are the lanes TD's which look exactly like the black ones in the top picture. If those are morosso stingers, than thats what my setup is...ive heard tons of fbodies, vettes, stangs, and none of them sound even close to what an lt1 with true duals sounds like. I have had 4 different exhaust setups now (single out the left came with car, loudmouth, magnaflow, then duals) and the duals sound by far the deepest and most pissed...cam + true duals :thumb:

actually i am almost positive that both are lanes with stingers good eye.

if you really want it out the back look into getting the stock piping that goes over the rear axle, then you will have 2 that were specifically made to go over it.

where would i get the stock piping that goes over the axle at? and also where do i get all the piping anyways, jegs or something?

Im almost considering just going dumps after seeing all the extra time and money it will take for the rear exit...that lanes true dual with the stingers looks nice also.

watch the for sale forum and ebay....they are always for sale...usually cheap.

specially since you don't need the muffler

post in the wtb section, this is a theory that it will work i don't know if anyone has done it. imo it is not worth the time or money to run it out the back.

as for the piping go to the muller shop and hand then 2 dynomax bullet mufflers and a summit universal x pipe (NOT THE KIT) all 2 1/2 inch. print the pictures i just posted of the lanes and say i want that. i paid 210 total INSTALLED. i spent 120 at the muffler shop, thats to fab up and install. they have the piping.

as for the comment on the lanes with stingers, this is exactly what it will look like with the dynomax bullets. and you can kinda see the indentions where they hit the underbody to get it closer. this i where the dents will be in the back seats that will be covered by the cusions.


sorry still no pics its still cold as nuts, its supposed to clear up soon and i will get the pictures.

I was looking into Bassani true duals, keep my hooker headers and no cats. Two Questions though- Whats the ground clearance like and does SLP make a muffler that can be used with the dual set up?(haven't found one) I had bassani exhaust on my 99z and it was just too raspy, not deep.
Oh and Guys- keep the answers simple-you're talking to a chick here.

THANKX!!;)

Basssani just came out with A True Duel Set up....800.00 bucks and they claim 20 Rwhp

if anyone spends 800 bucks on an exhaust system they are just stupid, the set up that i have is 640 total= coated longtube headers true duels x pipe and dynomax bullets. i assure you nothing else is going to yeild a better gain or sound.

yea listen to critter....do it urself....wayyyy cheaper....thats what im doin this spring :) longtube headers $400 true dual setup dumped used $150 clamps etc $50......

extras.. Dual E-Cutouts $300 for right after the collectors! :D

So,
I think im going to just do dumps because of the simplicity and $...The last thing i need to decide is, which size dynomax bullets should i get, the 16 1/2" long with the 2 1/2 in & out. I just noticed on jegs, that size bullet is the only one with the 2 1/2 in/out so thats prob. the one, right?

Also, do i need to buy the turndowns and/or reducers, or is that something i should let the muffler shop handle? besides that i think ive just about got it figured out w/all the help:D

i have the mufflers you just described, same size and all. do you have the stock exhaust manifolds or lt's?

i have the mufflers you just described, same size and all. do you have the stock exhaust manifolds or lt's?

Just bought some Ceramic coated Pacesetter LT's

you will have to do some welding on the headers, to but a flange then the reducer then piping x pipe mufflers i would have a muffler shop do it. i forgot but i had a buddy weld the flange on it as well as the reducer.

Ok, so it might cost me a little bit more then...and so i SHOULD buy the two reducers to bring to the muffler shop then? and they should have the flanges?

check before hand

check before hand

gotcha, well looks like its time to call up the muffler shop today and get some quotes ect... thanks for all the help and ill be sure to post up some pics after the install is done! Hopefully very nice pics :D and some vids,haha
