I have been trying to figure out what i want to do with my exhaust on this car since i bought it two years ago. every setup I think about, there has been something i didnt like. I guess the benefit of not having money to attack this is having the time to figure this out lol. Anyway, when i couldnt sleep last night this crazy concept popped into my head. I have subframes, so space under the car is an issue for me. (Unfortunately my car is on the other side of the state, I cant just crawl under and see if there is room.) I think this could actually work, and i wouldnt be experiencing clearance issues from the middle of the car back as i would with duals down the center. As far as ground clearance I would just have to be worrying about the primaries, and my y-pipe-that-doesnt-really-Y

on to the idea. Im going to have LT headers, and I basically want to have an exhaust shop fab up a custom X-pipe with cats. The x-pipe will tuck in the location of the stock cat, and I would have duals running back to the "cutout cavity" beneath the rear passenger seat. Reason for this would be to run the duals in the location of the current/factory I-pipe. at the end of the duals, there would undoubtedly be a set of dual e-cutouts, and the duals would Y together probably right about where it goes over the axle before going into my 2OTL. I will make use of the new board feature and provide a cheesy illustration. Mind you this is a very rough, as well as cheesy illustration:



My intentions are to have the best of all worlds. an excellent exhaust note is most definitely my number one priority. This setup would give me the ability to switch between loud duals and a quieter single setup at the touch of a button, and still have decent clearance from about the middle of the car back. Could this possibly work or have I been smoking something a bit too potent? Anyone every done anything similar to this?

 

1. That would accomplish squat if it goes back into one pipe

2. No way will you fit 2 exhaust pipes in that area

3. Your car will have just gained another 80 unneeded pounds

 

I agree with the extra weight. I really don't think your idea would be practical, but it is a good idea in theory. Might as well just run a Y-pipe into a cat and then a cutout and then back to the muffler.

 

1. If the cutouts are open, then it would accomplish basically an open true duals w/ x-pipe setup

2. That's flat out wrong. My car has true 3" duals dumping at the axle. Not only will it fit (gotta bang up the floor pan a bit to get a little additional clearance, but dual bullet mufflers fit as well). I also have great ground clearance as well

3: The piping won't be all that heavy. Actually, if pulling a stock catted Y-pipe in favor of this, weight will be similar.

I'm not a fan of this idea though, because you really could just go one step further. Buy the BMR upper brace, and you can run dual 3" pipes over the axle. Run a couple mufflers out back, and you'd have true duals all the way back.

 

I would just run a y pipe setup, but with dual cutouts right after the collectors for open headers at the flip of a switch!

 

im not familiar with that brace or where it goes, do you have more info or pics by chance? If Im not doing what i posted above I have to decide between single exhaust or ditching the 2OTL and going duals. either way i go, im firm on having cat(s)

 

while thatd be great for track purposes... i dont want my cutouts to be quite that loud... a bit overkill IMO. I wouldnt have a problem with having cutouts up there, but i wouldnt put electric units on them and I would keep my single cutout in the back with the electric unit on it. The only problem i see with that is the added restriction of all those cutouts when closed.

 

What about true duals that go from the headers --> cats --> x/h pipe --> cutouts --> the quietest mufflers you can find?

It could be a relatively tame sounding dual setup, but uncork the cutouts and it will be nice and loud, but refined somewhat from the cats?

 

If I could pull that off I would, but idk if they would fit (or in other words have reasonable ground clearance) with my subframe connectors.

 

interesting idea

but i'm not so sure the X pipe would be needed. yeah it will help with scavenging and sound, but how often are you gonna run the cutouts open to really utilize those small benefits

here is a killer set of duals, over the axle that you can use for ideas.

for the panhard relocation bracket go here (scroll down a little).

i was thinking about tracking down 2 sets of original exhaust tubing from an fbody, and mounting them side-by-side back out to the rear of the car. should be inexpensive since alot of guys throw the old pipes away. and it's mandrel bent 2.75" tubing, pre-formed.

 

???

 

thanks for that info, i take it if I want to run duals all the way back ill need a torque arm and a panhard bar?

cutouts function as mufflers when closed... my catback was probably almost 50% louder before i had the cutout welded in. whether or not they add a significant ammount of restriction, i cant say for sure, that was just an assumption.

 

teke184, Is this a whole cat back x-pipe kit that can be bought or did you fabricate this set up. It looks super nice and sleek. Doesn't look that hard to route it if it was pre made buy the manufactor.

 

it's a bassani exhaust. as far as i know it's available for purchase, but i dont' know where....and i'm pretty sure it's $$$$

it's 2.5" tubing and i think stainless, so i'd bet it's over $1000 for damn near it
but itt is sleek. talk to mrr23 the pics are his...or call bassani


why would you need a torque arm?? that should have no interferance for the exhaust. the panhard relocation kit is probably needed, but i'm not sure.

and i think you're smoking something if you think your exhaust was 50% louder with a cutout installed...even closed.
it should make no difference, and very minimal decrease in flow.

sounds like maybe you had a leak in the cap...which made it louder. mine was no different than the standard catback after the cutout was put on.

 

nevermind about the torque arm, i was looking at a different setup.

about the cutout, i said the exact opposite of what you think. It got quieter, not louder
