Y-pipe H-pipe or x-pipe?
I've also heard H-pipes that sound like ****. It is all personal preference.
This topic has been beaten up many times. It all turns into a heated debate that ends up being useless since no one has actual facts to back anything up. Just wait. This thread will end up exactly like the rest.

in general:
x for higher end power
H for low/mid power, sound
y for good ground clearance and ease of install
any can be made to do what you want, none are cheap if done correctly

X-pipes scavenge better than H-pipes. You will see significant gains with a well-made X-pipe over a well-made H-pipe on the top end. It will be more than 1 horsepower. However, you'll lose low end torque with an X-pipe. H-pipes push the horsepower curve lower, so you'll make more power lower in the RPM range.
i have an h pipe. i ran a buddy of mine with an x pipe same mods- lt's/dumped/bullets his was m6, mine was a4 got him by half a car. so u be the judge.. but both are good ..
x=sounds more like exotic ferrari type car, higher pitched, semi raspier
h=more musclecar type sound, deeper, throaty
thats sort of over generalized, buit you can get an idea, just go to ls1 sounds for the difference in sound
