  1. Looks good and Sounds Great! 5 Star Review

    It was a pretty easy install on my A35. I had to drill out the holes for a better fit, but after that she bolted right up. Added 5 mph to my stock ride, plus I got several compliments on it's look and sound after a quick ride around town.

  2. Nice pipe 4 Star Review

    Great for top end, will bring your speed up. I hit 50 with this and a the 26t/22t gearing, and a pretty broken engine in need of major transmission repair, but that was also downhill. Flat out hit aroundabout 45 before my rear exhaust mount cracked. Definitely recommend a 70cc kit to cope with the lack of bottom end, but without it just run stock gearing.
