Anyone made there own custom cat back exhaust for these sedans? I probably will weld one up out of 2.5 SS with all mandrel bends. I have not had to much luck finding an exhaust pipe that has 2 merc style tips. This iswhat I found so far. With the 2 silencers and 2 stock exhaust cans removed this should have a nice rumble. If anyone has another idea on a can it let me know. also this way if it sounds bad I can just go back to the stock cat back and hear almost no sound.

Couple of links to help, Also you may want to try replacing the mufflers with straight pipes. Few members have had good results doing that.

 

thanks for the links. I like the 3.5 exhaust. I welded up a similar setup 3 years ago when i was one of the first people running a complete 4 inch exhaust turbo back on a rx7. I will say i love the idea aof using the stock tips.
