hi everyone i want more sound and horsepower i have a AP2 05 with kn intake and skunk 2 mega power exhaust , what test pipe you recomend , BERK or SKUNK............YES i did the research buttom... please some advice.

 

a tp is a straight threw pipe. it doesnt really matter which brand you go for because there all basically the same thing.. but quality is something you need to worry about. people report that the welds on some ebay tp's crack or break over time. but the biggest thing that will change the sound/hp is the pipping diameter. its best to match up with your cat back. so if your cat back is 70mm get a 70mm tp.
