Gents, looking to add a performance muffler and tips to stock exhaust, would appreciate any feedback. What is the best balance of performance and sound?

There's too many good ones to name, but I like magnaflow, flowmaster, borla, and SLP loudmouth mufflers the most

Magnaflow or Spintech FTW!!

Only get a Slowmaster if you want to sound good and have a cutout.

All exhaust sounds weird with dod period...if your just adding muffler your not going to gain a ton of performance so whichever brand you decide Will make the car sound better without having to worry about sacrificing performance....you could even do fowmasters....that's for you ls1 lol

you wont want the stock tips when you see the diameter of them. . .

I betcha the stock tips are the most restrictive part of our whole exhaust.. well maybe not quite , but they sure as hell arent helping anything.

If you can see straight through it they are all the same. The real question is do you do a 2.5in set up 3 in. You may as well go from the downpip back.

I just uploaded some clips of passbys in DoD mode, it doesn't sound weird at all! You'll need a subwoofer to really hear the bass in it, but don't be worried about DoD mode!
