Charles Creech (verified owner) –
great sound over stock muffler. was music to my ears!
Al Conte –
I decided to upgrade the exhaust system slightly on my WS6.
After reviewing the work involved, I simply cut out the old muffler system, keeping my dual quad tips.
I welded in the SLP II with a splitter coming out into both exhaust tips.
I gained clearance, got rid of some weight, and the car now sounds like a WS6 should.
And that’s a quote from the muffler shop guy up the road.
I stopped for gas and he came out and asked what kind of system I had.
He sells magnaflow stuff.
He commented that the sound of my SLP is how a Trans Am should sound.
Then he asked where I got it. LOL
