Thread: So, this is my exhaust plan...any thoughts?

'98 GP SE sedan, 3.1L is what I have, and here's what I was thinking: Magnaflow 91006 high flow cat 2.5" I/O (good for up to 4.2L displacement [EPA] and 4.0L displacement [CARB]), Aero Turbine AT2525XL resonated center muffler 2.5" I/O, 2.5" to 2" Y-pipe, dual 2" runs to Tanabe Medallion touring mufflers. I'm not looking for significant power/mileage gains, or for idiotic neighbor-waking noise; I just want a little more sound with a deeper note. Does anybody think this setup will get me what I'm looking for, and if not; why? I heard a very similar setup on a 300zx recently, and was pretty impressed with the mellow--yet menacing--sound it produced. I'd appreciate any input you guys can give--yay or nay--but, since this is my first thread, please try to be nice if you can!

I use magnaflows on my 3800 stuff.. does a decent job of keeping things tame around town, and a good noise when you are on it.

@ctracer: I thought about keeping the stock cat and res, but they're the original units; and will both need replacing sooner or later. If for about the same $ as OEM pieces, I can get something that breathes a bit better; wouldn't it be better to go ahead and do so? The thing is, I don't really want loud, I just want a bit loud-ER, you know? I'm shooting for more of a bassy rumble than anything else.

@darkhorizon: I know Magnaflows are good, and I'm not against using them; I just really want to try something not many others have. As long as a particular muffler gets me the sound I'm looking for, I could really care less where it's made...

Thanks for your input, guys! Anybody else?

Why though? Its a 3.1 SE. Even if you got the perfect exhaust setup and made it sound decent it would still always be slow as long as its the 3.1. Spend that money on a 3800 swap?

3100/3400 sound worlds better than a 3800.

And worlds slower... Just giving my thoughts on a better idea..

@Max: I thought I already said I'm not looking for significant performance gains...and I don't know about you, but I don't have the cash for an engine swap burning a hole in my pocket! Also, I have no intention, desire, or inclination to do an engine swap! Please try to keep any comments on point here, this thread is about what I have in mind for my EXHAUST, and nothing more. And by the way, yours might be a "better" idea...but it's a whole lot more expensive; for something I don't even want.

@blueguy91 Yeah, those look about right. I already looked into a set of GT bumpers, too; just because (1) I hate the SE nose, and (2) both of my original bumpers are looking a bit the worse for wear. As far as the glasspack goes, my understanding is that the brand doesn't really make much difference; but is there something wrong with the Aero muffler that I don't know about? Also, I already have a 3" smooth-bore intake my late brother fabricated back when I first got the car, so that half of the intake/exhaust equation is taken care of.

I'll be sure to check out Milzy when I get a chance, thanks for that.

I see...thanks for the info blueguy!

I agree. I think the 3100 has some capabilities within it. You just have to research what works best and not overdue it! I am modding my 3.1 and have been told by a lot of people that I will see some gains. It wont be throwing on another 30 horses but it will make a difference.
