do the pair valve mod and backfiring will stop if you have it with a slip on.
well i talked to a prts place and they said doing the pair valve will mess up my bike i dont see how but they also said i need a pc3 or else it will always backfire any advice

Don't waste your money on slip ons...get a full system![]()
I second that. I would have kicked myself in the Butt, had I not gotten the slip ons for free. I finally went with a brock alien head full after the slip ons and a drastic improvement in both sound and performance.

screw a power commander! get your pipes, pv mod, and tune with ecu edit. there, I just saved you about $200 and got rid of your top speed limiter the right way! Its ok, you can thank me later.![]()
Thanks.
But I thought the PV mod was only for Gen I Busas?
Or am I thinking of another mod ?
