It's loud but I'm more about performance than I am looks or sound. Spintech is one of the best performing mufflers out there, it just so happens to sound really good.

Do the catless, resonator delete and keep the factory mufflers. Shouldn't be too loud.

When I wanted a catless over a year ago he couldn't make 'em. I had my catted one made with a flange before the cat so i could make it modular myself.


And here's a vid of my catless and Magnaflow set up

I have a catless downpipe without a resonator and it sounds great. Hardly any drone and a nice throaty sound. I get a lot of compliments for the exhaust and when I tell them it is mostly stock most people do not believe it. You'll really wake the motor up with a catless downpipe. If you do go catless, make sure you delete the P-0420 code so nothing gets set off like a SES light. Hope this helps.

I had a high flow cat on my 02 MC SS, so I deleted the code and it still didn't pass inspection. They said it was the 420 code, but I had that deleted months before inspection was due. The DP was the only thing that would have set off the 420 so I dunno I was thinking bout getting a DP for the GXP, but if it will not pass NY inspection then I am not going to. But I really want to because the DP on my 02 was a really good upgrade!
