Does anbody know if using a silencer in the muffler will hurt the turbo and piping. I put one in to cruise around town last night and it sounds like the turbo is pushing more air or there is a leak after I put it in. Also I can not go past 20 psi.

 

Hurt the turbo and piping? No.

However, it creates so much backpressure that you lose more power than if you just had the stock exhaust. Don't mess with that thing, man...
