damn 220 degrees??? that's too much man . the most should be 210 degrees .

I think that exhaust is a good choice.
I've heard that the F1 is a exhaust which has a pretty high rpm.

Soon some testing results of the KRD exhaust everyone is talking about.

220 ex...........
150 transfers.............

you sure you wanna run that set up?
you'll gonna have a migrain tuning your set-up.
get rid of KRD cilinder & use MHR Speed/EVO/ Manston cilinder. bigger isn't always better when it comes to ports.
