Protomotive 3" exhaust
Dear all,
Yesterday i just received my Proto 3" exhaust .Today i took the car to the shopp and did install it.Everything was very easy,no need for any modifications,there is 0 drone at all RPMs and it is hitting 1.5psi boost more on the same ebc setting which means the flow is much better.

Looks great! Thinking of switching mine up for one with no cats. This looks like a great option.

+1 and it is performing and hitting the boost like on race pipes
I was running the switzer exhaust.when ebc was set to 21 psi the car was boosting max 20.4.But now on the Protomotive exhaust you can see 22psi.on normal driving no drone at all like you are driving a bone stock car but when you floor it the sound is agressive

No drone at all,it has 6" muffler at each side.
