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

Don't think I've seen this done before however I can't see why it wouldn't work. The same exhaust manifolds are used in both.

Is there a difference between the SS and the regular 5.3 exhaust setup?

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.

If you have AFM with anything but the stock exhaust, it will sound like garbage when it kicks in.

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.
