I was just curious if there was any problem running like this? Right now I have a 2.5" X-pipe with dumped mufflers and I don't want the dumps anymore. Rather than spending money on some new tails, I think I still have my stock tails sitting around somewhere and was wondering if I could put those on? Would this cause any problems? I have a Dr. Gas x-pipe(no cats) and Hooker aerochamber mufflers. Would running 2.25" tails cause any issues?
 
i run 1 5/8 LT's.. BBK 2.5 X.. and stock tails with 40 flows.. it seems to flow just fine. If it had a problem with the tailpipes i'd have noticed by now. But seems to work happily.. it probably added a slight back pressure which you need some
 
Anyone know where I can get the "over the axle" portion of the exhaust system? Or is this something I will have to have a shop fabricate for me? I think the problem I'm gonna have is some shops won't work on exhaust systems that don't have cats. Is there anywhere I can get just that portion of the exhaust?
 
That's basically why I'm adding the tails. The dumps were cool at first, but now they are just annoying. I can't hear anything inside the car. It's cool to pull up next to someone or drive by people and have them look to see what's making that rumble, but I can't stand the inside noise and the drone anymore. I'd rather hear my music than my exhaust these days. I have the 3:08 rear gear so driving down the highway in 5th gear in right smack in the middle of the drone zone.
