I was contemplating what exhaust/header set-up to go with on my 3rd. gen the other day and I came up with a few ideas. Right now I have shorty headers into a full 3" single exhasut into a flowmaster 80 series muffler.

Anyways, here are a few idea I came up with. They all include Hooker cearmic coated headers, so I'll just show you guys everything from there back:

Option 1: The 3rd one down.

Option 2: Some 2.5" piping off of the headers and then into the h-pipe. And then go back to some Dynomax bullets with turndowns before the rear axle.

Option 3: Same as above but with Moroso mufflers.

Option 4: X-pipe and then dump it with Dynomax bullets from option 2.

Option 5: Same as above but with Moroso mufflers from option 3.

Option 6: Get the BMR panhard rod re-location brace and then run a 2 1/2" dual out to the back of the car with an H-pipe and Warlock racing mufflers. I like the idea of these because I can go from no exhaust to full exhaust. Basically like cut-outs.

Option 7: Same as above but with an X-pipe.

Allright, so let me know what you guys think. I'm looking for what will offer the most performance and sound good, not raspy or anyhting like that. Oh and I kinda just threw in #1 just to see what you guys would say, but I honestly wouldn't mind getting them if they're not like open header loud.

 

Anyone?

 

With any dual exhaust, it seems that there will likely be raspiness unless you get a good sized muffler. Also, you'll be losing a bit of ground clearance with that setup too. The exhaust can be made to tuck under and not lose clearance but there will likely be a lot more bends= less hp. We had a discussion going on over at www.gcfba.net about this in the past week.

Really, as always, I'm just gonna reccommend a good header and GMMG. It's pricey but in the end it will get you the sound and performance you want.

 

I was thinking it would be easy if I ran some Hooker headers just into a 4" sinlge out the back and have it exit on the drivers side. Pretty much unrestricted flow and it should flow fairly good. I saw it on another site somewhere. On a 4th gen though.

 

Well, I know mufflex makes a catback like that. But I believe theirs eventually splits into 2 mufflers, or just dual outlets. It really depends on how much hp you're making too. No need to go overboard on it if you're not pushing that much. Either way, get some sound clips up when you're done.

 

Does anyone else have any opinions on the exhaust combos in the first post?
