Well I have Mac Headers and ORP with a cutout and I was wondering if I replace the exhaust with Bullets if I will lose power?? I am also doing this to rid some of the weight...Someone in the area told me that they flow about the same..I THINK the bullet im going to buy is Dynomax,,

u MIGHT lose a slight amount, I doubt u would notice any loss at all. IMO the Bullet is the highest flowing catback, just like the loudmouth. The bullet has no baffles for air to circulate like a glasspack, just flows right thru. on my stock 98 6m and JUST a 16" bullet I pulled 320hp.

 

Cool, I wonder if anyone here has ever tried a dyno on this before?? Ill try a search though..

 

I also do not think you will lose any power, that seems like a pretty good flowing exhaust as compared to a cutout, maybe even more so ? I have not seen a before or after dyno though.
