I'm working on a TVS supercharged Camaro at the shop right now.
It has JBA long tube headers, small cats and stock exhaust.
Engine has forged pistons,rods,and crank.
We are checking the motor out and upgrading the valvetrain for something more TVS supercharger friendly.It still ran the stock valvesprings and trunions

Currently the boost is set at 10-11 psi.Will probably keep it there for now.

I know I have to remove those darn cats.
Did anybody have made 600-650 rwhp (M6) with the stock exhaust?

Or is their something else that is out there that would flow better,but also as quiet? Customer does not want to draw attention.

Just asking for opinions.

Thanks in advance.
