Anyone have experience with the APR bi pipe and if they actually noticed some fixes with the throttle body?

 

My APR bi-pipe does its job, it probably flows a little better than stock but nothing noticable. I just dont have to worry about the TBB anymore, and it will be great to tap for a H2O/Meth Injection system in the future.

 

I'd imagin the biggest gain is probably reliabilitypiece of mind on at least one part of the car
