i have an 05 gt and i was going to purchase an off road xpipe from brenspeed.. then i saw an off road H pipe? any difference? pros, cons? i have the borla stingers. axle back by the way,... please post any opinions and experiences thanks in advance
i got more power from the x pipe in my setup...by like 13 hores and a little bit more in torqe also, not much but it was a plus both ways with the x pipe....and also to me it sounds better

Any X-pipe set up will give you more of a "raspy" tone whereas the H-pipe will give you more of a deeper rumble. I ran both and liked the h-pipe set up better. However if you're going cat-less, be prepared for failing emissions and getting a lot of popping when decelerating. its nothing to worry about just nothing preventing the back pressure with the cats being removed.
+1 on the pypes being a lower quality brand. I have them now and I'm selling them just because I keep having exhaust leaks from the collectors, get a good set of midpipes (i.e. MAC, Hooker, JBA or Magnaflows).

I had the offroad X on my Roush and it sounded wonderful and it was faster than the C300 with cats and J pipes. +1 on the emissions.....your state better not have inspections
yea they dont check emissions here so thats not a problem.. i was going to purchase the H pipe from brenspeed since i already have the tunes.. and i get a free tune to shut off the check engine light.. the problem is.. i am told that the H pipe is now a 4 piece.. and they say that causes alot of exhaust leaks.... it used to be a more solid 2 piece.... what do u guys think?>
I just installed the Pypes H I bought from Brenspeed about a week ago. Yes it is a 4 piece now, but if you get good exhaust clamps you should not have any leaks. The 2 clamps they give you to clamp the down pipes from the manifolds to the H sections are not very good. I went to the auto parts store and bought 2x 2.5 inch exhaust clamps (similar to the one supplied for the crossover H section). Anyways those worked very well. I did take mine off last weekend to weld it just to be sure it will not leak. From what I could tell I never had or would have a leak with the clamps on. The only problem you might have with Pypes o/r H is a tight fit to the exhaust manifolds. See my post below on how I made a tight fit.
