I was just curious about which exhaust system you guys think is best for the LS1 z28. I was looking at B&B Tri-Flow, GMMG Chambered exhaust, or Loud Mouth 2?

So what do you think about the B&B Tri-Flow exhaust system, or what have you heard bout it.

I have the Hooker catback and its probally to quiet for you. It has a good rumble at idle, no interior drome racket and really opens up at full throttle. But then it quieten right up when you go thru that license check.

Get the GMMG and call it a day. Best sounding exhaust I've ever heard on an f-body.

Ive been asking the same question and was told to go with Magnaflow or GMMG exhaust. I was told that Magnaflow sounds awsome! with LT's. Magnaflow is also cheaper than GMMG.

I love my Borla. Never heard bad things about GMMG though.

I've had Borla, Magnaflow, Loudmouth and custom true duals. Currently, I'm running QTP's through a RT catted y-pipe and stock SLP centermount with a Magnaflow muffler making ~430rwhp. I love the sound of my current setup and would only consider dropping the cats for a change. On a stock car, it's hard to beat the sound of the Borlas with the adjustable plate completely open. Get an electric cutout for it like I had and you can tone it down whenever you want incase you have to go somewhere fancy. :)
