X-pipe Q's

[DBlightning]

How much of a power difference is it between:

Stock pipe vs Cat-pipe (x) vs X-pipe

Looking to do 13.5 with no internal engine work.

I'll take a stab at this. I believe the stock cats are quite restrictive. I switched to the x-pipe and it got a lot louder even with the stock cat-back. I'd say when you have enough power to run a 13.5 you'd be picking up around 15-20 horse. The cat-pipe naturally won't flow quite as well as the straight x-pipe, but I think it would be a great improvement over stock, so I'd say 10-15 there. Any other opinions? - Brian

I would have to agree with gasguzzler. I just finished putting my x-pipe w/out cats on Thursday and you do have to get used to the loudness, but it does free up those ponies at high speeds.
