40 series flowmaster

has anyone installed a 40 series flowmaster on their v6??? was it easy and how did it sound (even in higher rpm's)??

thanx

I'm not 100% sure on this (pretty sure though) that the 40 series is more for 5.0 Mustangs. Most of the guys here that install Flowmaster exhausts go with either the 80 series or the American Thunder. IMO, with a bigger I-pipe both will sound very good. I heard a Camaro yesterday with a 3" pipe and a 80 series...sounded MEAN!


Good luck deciding!

in that case...does anyone know which sys of american thunder or flowmaster would sound the best with not too much low end torque loss

Flowmaster makes a new system for the 3.8s with a resonator on the I pipe. I think the part number is 17358.

wuts the resonator do for it...how will it sound?

if anyone knows or has done this on their 3.8, can i have ur IM sn cuz i need to talk to someone 1 on 1

thanx

I heard it takes away alot of the rattle you hear at high rpms, but it also takes away some of that deep idle and rumble we all like. I personally have 3" catco highflow cat, 3" S pipe with a 3" flowmaster catback WITHOUT the resonator and I still think it sounds damn good for a V6. However, mine does rattle a bit up high, but it's not a hondaish type rattle.

my brother has a 40 delta flow on his 2.8 s-10, and it sounds sooooo much better than the 80 on my car:cry:

how was the power gain after he installed it??? and how hard was it for him to install?

You'll maybe see 10 hp from a catback for a V6.

wut 40 delta series system do u recomend for the 3.8? and is the assembly and installation easy (can i do it in my backyard)??

I don't recommend the 40 series. Get the 80 series american thunder catback. It sounds alot better.

i heard something like you have to drop part of the rear axle though for the flowmasters is that true? and hows the power gain on the flow master 80 series?? if i get the 3'' pipes on the 80 series am i gonna lose alot of low end torque?

That's the one I had on my car. Today, I put on the B&B catback and to be honest they sound close. B&B sounds better, but both are quiet, just a tad louder than stock.

Only problem with the delta was at around 2k rpm the gurgle smoothed out and it sounded too high pitched, where as the B&B the gurgle stays and it is a little deeper. I've heard people put down the NOn delta, but the Delta sounds pretty good.

I can't comment on the AT or 80 series, having not heard them in real life.

ok... which sounds better and gives the best power gain: edlebrock, dynomax, B&B, or Borla???

oh also to add to the previous post where should i go to get the best prices on exhausts on the web or maybe somewhere else??

thanx

Really depends one which one you want. Summitracing.com jCwitney.com Onestopexhaust.com Tbyrne.com etc, jeggs.com etc are a few web sites to start. I got my B&B from tbyrne at $597 after shipping.

Jcwitney has a pacesetter catback for a hundred and something.

IMO, Borla and B&B are a waste of money for a V6. They are ALL about the same performance wise. Go with either a flowmaster (loud and gurgly), dynomax (mellow) or edelbrock (slightly deeper than dynomax). They all are around $300 for the catback from summit or jegs.

B&B is stainless steel, remember, so if you don't have a problem with rust then you don't need it. But if you do, like me...and a few other people in the same area, then it would be a good investment. And, no longer having to pull my hair out over my exhaust (i'm picky about the sound), that makes it worth it.

I can't say if its the best sounding exhaust, but it is close to the sound I had in my head, and each time I drive it I'm happy with it. :) .

Guess I need to add it in my signature?

Flowmaster 40, had it for better half of 4 years now. I have digital sound files if you want to hear it at idle, barking, and also at redline.

The 40 series is louder and with more rumble than the 80 series. Bein' out with the club I got the chance to hear an 80 and my 40 side by side. And you can tell a differance.

You live with more resonance, but the 40 is a Mans' Muffler

If I had to do it over again, and will. I'll run the American Thunder system with the addition of 3" pipe, headers, and an off-road pipe. Should sound a lot meaner.

E-mail me if you wanna get the sound files.

B&B is stainless steel, but aluminum don't rust ( i don't think it does). I personally heard a 40 series and it was the total opposite. Mine was deeper and less raspier. The guy with the 40 series agreed also. 2000camaroRs, it's really up to you. If money isn't a issue with you, then get a borla or B&B. Otherwise, go with a flowmaster, edelbrock or dynomax. Like I mentioned before, they are ALL about the same performance wise.

thanx everyone for ur input...it has helped alot!! i'll probubly go with the edlebrock or try to get a good deal on a B&B...are these stainless steal?? and can they b assembled and stuck right pretty much?? also one last thing.....where is the backpressure lost (causing a loss of power) at the i pipe or the rear section to the mufflers?? i guess wut i'm asking is where should i get the 2.5'' pipes?

once again thanx alot for all of ur help!!!

but aluminum don't rust ( i don't think it does).



LOL, I'm not sure either. All I know is that I don't like how the pipes on my blazer are looking. And a coworker bought a 40 series and pipes and he's already complaining about rust, etc.


Edelbrock is not stainless-from what I've heard. And, 2000camaroRS, I assume you own a 2000 camaro ( ;) ) , the catbacks only fit directly on for the pre 97. Though you can put it on with some modifications or maybe get a shop to do it. I heard that they sound good too.
B&B is stainless and comes with pipes and tips and do make a direct fit...though my dad said it was a pain to get the pipe over the axle...otherwise he got it on.
Edelbrock is cheaper though.

I didn't notice a lose in back pressure (I went from stock to 2 1/2), maybe a gain in mid to upper range. 2 1/2" would be a good move, heck a lot of guys like shortdog have 3", either way it'll sound and perform better than stock.

does anyone that went from stock to 3'' notice a real loss in power?? and also how did he get it over the axle if its not built to bolt right on?? also where do u lose the power: when the i pipe is too big or when the rear outlet pipes are too big??

thanx

I didn't feel any loss in performance with the 3" pipe, but won't know for sure until I hit the track and compare 1/4 times. Keep in mind, I had a 2.75" V8 I pipe before the 3" and ran 14.9s-15.0s all day. I bought my 3" I pipe seperate from the rest, so my catback is pretty much custom. I got the dynomax I pipes for 80 bucks from advance auto parts. They come in two pieces, so getting the pipe over the axle wasn't a problem. I'm not too sure if other exhaust systems comes with two pieces for the I pipe. Most systems (even V8s) have 3" in/2.5 out muffler with 2.5" tailpipes, but my flowmaster muffler is 2.5" in/out (part 42583), BUT it necks up to a 3" right at the muffler. I honestly don't think the inlet size on a muffler makes a difference performance wise. My tailpipes are 2.5" also. A good muffler shop can make a 3" I pipe fit on a 2.5" muffler.

Also, check out www.fbodyv6.com and www.firebirdv6.com There are tons of info on those sites. Do a search and a bunch of stuff you're need to know will pop up.

thanx everyone for the input...but taking into account the price performance and sound i think im' gonna go with the flowmaster american thunder 80 series with 2.5'' piping back to 3'' tips. This will be sure to give me same torque at low revs, and even more power at high revs (i wont hafta really sacrifice anything). Thanks alot for ur input it was crazy helpful to me in my decision!!

its been swell :D

You don't 'lose' torque power going with bigger pipe. You just notice a larger gain of top end horsepower. Sufficient enough that it feels as though the engine pulls harder up top, which it very well may. That don't mean you've lossed torque. You just don't feel it like the horsepower you've gained.

If you don't plan on doing some serious engine work there is no need for you to go with 3" pipe. 2-1/4 to 2.5 is all you will ever need.

Rusting tips and not indicative to any one exhaust system. It's the care that went into them and the quality of the tips - also the material plays a role.
Best thing to go with for long life AND good looks is polished stainless steel.
If you want chrome tips to last long, keep them free of water as much as possible, and a light coat of thin oil will keep them from rusting. = WD-40, machine oil, gun oil, etc.
