im lookin at a new exhaust and i cant decide what to get. i was looking at the review section and i saw the bpm tt turback exhuast. its a twin tip design which i like and its advertised as quieter than other exhausts. it fits my needs very well just wondering if you guys would recommend it. one question, the bpm site says i can pick a down pipe for the setup between a single dump and or twin dump. whats the difference?

single dump i would assume..is where all the exhaust gases goes into one big hole(like a bellmouth) the twin dump is where there are two tubes coming down and soon going to one pipe at the bottom. Either is good. Some prefer bellmouth to twin dump because they say it gets more hp others say that you can spool better with a twindump...its all up to what you want. I also think there is a really good write up about it on nasioc.com hope that helped

 

k thanx, anybody have any experience with the bpm turbo back?
