^--- Umm not so sure I understand your entire reveiw.....

But go for the x-pipe you will love it. I haven't even turned my music on since I've installed mine. I wish I had before and after dyno runs with my new setup to prove any power gains. But the Fabspeed cats, you can look right through them, not like OEM they are way less restrictive. Plus when you look up the tail pipe of the AA mufflers you can see all the way up to the X section of the Fabspeed pipe. The car is definitely running strong now.

Hopefully I'll have videos up soon
