Why should I share it. you and the Superbike basher's just use false information to try and discredit the results. You can't imagine the testing that has been done. But a little info on pipes, the MBRP tested with the best results on a stock bike.(stock air box). But with some additional work on the carb slide, it will probly make even better numbers. You can verify this by contacting 14MINS.

 

I understand the MBRP headpipe to line up on a DS like a stock headpipe. The result is a HMF slip-on will fit on a MBRP headpipe. However will the headpipe improve anything? Does anyone know that?
I was told it was hard to improve upon the stock DS headpipe unless you go heavily modded anyway.
