anybody know about this? discussion time!

 

that looks useful, if u want to create more backpressure in ur exhaust. its only good for avoiding tickets as long as u have stock exhaust, otherwise, most people pay for an aftermarket exhaust BECAUSE of the new sound and increased hp+tq. both of which u give up if u use the suppression pipe. besides, i have yet to see someone get a ticket for exhaust noise running stock exhaust.

 

im pretty sure it could be applied to aftermarket products. stock exhaust CANNOT get tickets..

 

wat i was trying to say is that its basically a throttle body for ur exhaust, when u have it WO u have max flow and the sound intended by the exhaust maker and get the advantages of freeing up some power. when its closed or only party open u lose flow and get a lower sound...u also lose power by increasing exhaust backpressure, this is especially evident on turbo cars where increased backpressure means slower turbine speeds means less boost means less power.
