Hello all new visitor here. I have a chance to purchase a trailblazer SS exhaust for my envoy with a 5.3 in it. Does anyone know if it is a strait bolt in or not. Thanks
You might just be putting on an exhaust system that somebody took off of their SS for a better exhaust system and if you have AFM it could have a ricer sound.
Is it known exactly what GM did to the exhaust, so it didn't sound like a moped when the AFM kicked in? Now this has me wondering how much the tone/pitch would change.
I did an extensive search for an aftermarket dual exhaust system for my 5.3 Envoy and could find none or even get answers from Magnaflo,Borla and others, I have to think that AFM was the reason.
More than likely. On the forum for the Caprice, that is the #1 complaint from any aftermarket exhaust installed. My son's Silverado with a cut off muffler sounds like a go kart when it kicks in.
