So right now I have a solo performance axle back and thats it. I plan on getting a x-pipe soon. I was wondering if there is any major performance difference if I keep the stock exhaust but add the xpipe and axle back rather then buying a whole new system. Thanks for any help

Not major. Some cat backs tend to claim 10-15hp i believe stock piping is 2.25" and most cat backs are 2.5". If you do a custom set up stay away from flow master. There are better company's that flow a lot better. Just do a search on here and google. Good luck

It's negligible. I remember reading the stock axle backs don't really restrict flow until you're over 400rwhp.

If you like the current sound with the solo axle back, don't get an x-pipe.
Just have an exhaust shop replace the crimped pipe between the mid muffler and resonators. Removing ALL the mufflers makes it much louder.

Ive seen youtube vids of solo axle backs and xpipe combos I like it. It sounds good now I just want a louder car you know lol, might even get long tube headers at some point.

OEM cats are the restriction. Until they are addressed, insignificant power gains.
