i have a borla catback. sounds nice and mellow but not aggressive. i want to replace just the muffler and keep the rest of the pipes that came with the kit. i don't want to weld anything, just clamp it on. what would be a good choice. i think the borla is a 3 chamber. i want a 2 chamber. something that sounds more aggressive, but not to excessive. i am thinking of putting a borla pro xs muffler on it. anyone run these? or have a better suggestion?

 

Your not alone man. Im about to do the same. I want a Magnaflow muffler!!

 

flow 2 chambers sound pretty mean

 

I need to listen to another 5.3 to see if i like the sound of the magnaflow or if I should stick with another PV muffler for my trailblazer.

 

Dynomax bullet(s).


Its really not that loud after a few hundred miles. When you get on it though, damn.

 

i am very happy with my edelbrock rpm series muffler.
