Should I buy a Test pipe? Need help

[08cosmic3]

I had the Corksport TP first and it fit poorly. If you don't have a 3" cat back stay away from it, many others have had the same poor fitment. I have the SU pipe now and it fits great. I did pay $200 for it back in the day when they were hard to get. I did notice a nice butt gain with the pipe and after a week took the pipe off re-installed the stocker and the difference was much more noticable when going back to stock. I have done the swap several times now and it takes longer to jack the car up than it does to make the swap.
