i'm using the stock exhaust with tp on my supercharger, the lack of unbearable noise is fantastic

 

I have a fully built block, with GT3076R pumping 18psi boost.

We did a back to back gains are definitely possible without getting much noise extra.

The biggest restriction is the factory Y split.

I have a custom made 3inch turbo back, mated to to stock exhaust cans. Nice and quiet!

 

Could you give me more info about your setup? How much Power are you making?

 

Although im sure there is "technically" a limit its more about how easily you want to hit your goal.

 

I made a touch over 500whp dynojet with stock exhaust and TP on my SOS S/C kit. I'm sure it was restrictive. My S/C will be up for sale soon as I'm going turbo.
