........on their 5.5 gen?

Curious to see if anyone has tried this. I would like a tad bit more sound from my exhaust with out going all out on an expensive cat back

 

You can't switch the entire exhaust, the ONLY portion that you're able to "swap" is the muffler. Not even the axle back either about 5-6" of the muffler and associated pipe. You'll have to weld it on as well and change some of the welded on hangers. The oem G35 sedan muffler uses a 2.5 piping size. It has been done somewhere in this sea of information... Was it worth it?? Haven't the slightest clue.

 

I guess that is what I meant, muffler. I need to replace mine sooner than later and there are a few in good shape at the junk yard

 

It's been done on 4th gens. It's huge and hangs down however.

 

Been there, done that on my 5.5 gen. Hangs ridiculously low and looks retarded. Sounded great! But looked stupid. I did not last long with mine before. I went and got cattman. Lol
