Default Crazy question. How do I quiet down the exhaust with headers?

I was thinking of adding some dynomax bullets or something similar to quiet it down.

What’s the most quiet axleback? I know it’s pretty crazy to ask. I live in a condo o I’m trying to **** my neighbors off as least as possible.

OEM valves closed.

Yep, stock mufflers with closed valves are the most quiet by far

Im loving it. I missed ls motors and this is a special one. Didn’t quite realize how expensive the heads were but you pay to play I guess. It’s already a rocket with the unknow cam. Good street manners. But the whole top end is getting swapped out and headers.

Sounds like an awesome car. If you like what's on the car now, but it's just a bit too loud, consider adding high flow cats. It will tame the sound a bit, and it might be a better and cheaper way to go. FWIW......

Im leaning towards it. I just got a new set of kooks and x pipe for $2000. So I was thinking of adding dynomax bullets but I am unsure of ground clearance
