i was wonndering witch set up would be better i have a after maarket H pipe i was going to run glassbacks with no cats and tips outt he back or run no cats and spin tech mufflers righ after the H pipe and dump after that witch sept up would get me more hp i asked this cuz i dunnno alot about backpressure

 

the turndowns would prolly sound better, everything else being about the same.

 

i have turndowns with magnapacks and im about to instakk a bbk off road h pipe ....... and right now it sounds way better than any "out the back systems" imo

 

but do u lose power cuz there is not enough backpressure?
