Best advice I can give after a ton of testing and research is either a stock gt500 cat back ($1400) or for less backpressure a stainlessbros 2x3” resonator mated to a corsa touring axle back.

Yes. It may or may not work with tte
Gt valence but if you’re swapping then that part wouldn’t matter. The only remaining issue is that the connection at the front isn’t the stock 2.25”. I am told it’s 2.75” like the rest of the gt500 exhaust.

I went with borla s type but it was still loud AF. I ended up cutting in a couple bullet mufflers by the xpipe. Still loud but much more Bearable. Sounds good too. Gets a lot of compliments. If I was doing it again I'd probably try the stainless bros resonator instead of the bullets.

Although I'm not sure it's still an option, I have the loud valve boost actuated cutouts on mine with a Gibson catback. The catback was on the car when I purchased it. It screams when those loudvalves open up! Fairly tame otherwise.

Unless things changed in the last year, no they are not. I planned on running those with stock exhaust bur had to change my plans last minute.
