H - cats + flows + side exhaust = unbelievable sound and lots of rubber necking. You won't be disappointed!

o/r ?........... if the county where you live requires emission testing then make sure you get cats.. it sucks to change it every time you have to get it tested.

x or h?.. X is a little more raspy.. H is a little deeper.

I personally have o/r X pipes on mine and I think they sound awesome... it's still deep but a little better punch.. but that is just my opinion.. as 20 different people and you will get 20 different opinions.

well id go o/r no matter what. to change it out really is but 20 min not too hard. but once again that is my .02 theres so many different sounds between x-pipe and h-pipe with different mufflers and everything
