Hey guys, and girls, I was wondering if anyone would know if the 07 sedan exhaust would fit on the 04 sedan if I relocate the evap box? Obviously the rear section is different but what about the rest of the plumbing to the cats, would they run in the same location as the 04 exhaust (over and under the sway bar...etc)? Maybe someone who had the 03-06 sedan and switched to the 07 would know more about this. I e-mailed stillen about this and of course they say it couldn't be done, big surprise. From pictures I found it looks like it would work. Even if the plumbing is different, are the cats the same for both cars, like the size and flanges? Thanks.

 

Another option would be to get the stillen exhaust for a coupe and use the X or Y pipe to connect to the cats, and connect/weld that to the 07 sedan stillen exhaust from the middle resonators back. What do you think? Are the pipe sizes the same for the coupe stillen and the 07 sedan stillen? I know this wouldn't really be that cost effective if I had to buy both systems but could this be done fairly easy?

bump, any input?

 

Anything is possible, but i don't see the point. My stock diameter was 1 3/4 on my 07.

 

You are better off either having a complete custom one made like I did or going with one of the coupe and modifying it.

 

Yea, it would be easier to modify a coupe system like the HKS style. I just don't want it to be too loud. Any suggestions on a subtle tone coupe system with 2 seperate mufflers/canisters?
