I had CAI, And y-pipe.

Then I got the B-pipe, and felt a bit of low end lost on the launch.

I've heard all the stories about back pressure being good, and being bad.
I tend to believe that Back pressure is always bad, but what happened to my low end torque??

Has anyone else noticed this?

 

haha we talked about backpressure a bit at the meet last time...ive been under the impression that you need some backpressure for low end. but the faqs say backpressure is always bad
