I got the gmpp exhaust and well, i used to have 2.5in exhaust with just a resonator, much better than stock, but it was loud. So i figured the gmpp would be the best of both worlds, but unfortunately im noticiting the gmpp seems to restrict some flow up top. So i was thinking of removing the resonator on the system just leaving the muffler it came with and the rest of it would just be the mandrel bent tubing. What do you think...Picture of what im thinking of removing, yay or nay ???

 

What is accelaration like with GMPP catback ?

 

try it and if you dont like it try it with a new resonator or a glass pack
