How Much Louder Are Headers Than Muffler Delete - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

So right now I have LS3 with stock everything except the mufflers are cut out. I honestly don't know how loud it is because I've never heard a Camaro with muffler deletes driving by so I think it's quiet but I know it's not.

So I plan on getting 1 7/8 LT headers with highflow cats and JBA 3 inch catback. How much louder is this setup than the muffler delete setup I have on now?

The stock cats muffle it a lot . I went from muffler delete to headers and hfc's and Flowmaster exhaust. With headers and hfc's was louder but sounded way better. Cammed now it is freaking awesome.

If you want some sound you need long tubes. Muffler delete is still very quiet.

I went from muffler delete (stock headers and stock catback) to the stainless works retro 3" catback. It got a little louder but not much. I added 1 7/8 long tubes with no cats and the sound got SO much louder. So so much louder lol

And yeah only a muffler delete was way too quiet for me..
I'm not sure if the majority of the volume came from the cat delete or from the long tubes.
Can anyone answer this? I know 4 cats restrict it hardcore..

Ya I can't wait for the new setup.

Cat delete makes it loud, headers make it sound good.

Ya I don't need as loud as possible. Gonna get highflows. I was just seeing how much louder that setup is than muffler deletes.

It's going to be permagrin loud. And if you add a cam (like mentioned above) it's going to be even louder!

Kooks long tubes & high flow cats, Corsa cat back.
