I have magna flow cat back on my car and its really quite except at WOT. Is this one of the lesser sounding systems out there???? I use to have flowmasters on my l98 camaro and it was waaay louder. Granted I was running edelbrock headers.

Exhaust on these cars is totally different from any other car because of GMs sorry "Y" configuration. But from my experience (and money) get the loudmouth system or straight pipes. If I could go back and start over I'd try the true dual some ppl have put together. I came from fixing up mustangs forever to my first TA so I went with Flowmaster....terrible mistake if u want an aggressive sound. So in a nutshell, Headers (or off-road Y) + loud mouth (or straight pipe) = great

Thats another good idea, and should increase it a little bit. Although gutting will probably not pass emissions, but you could however find used stock cats and gut a pair and swap both for just emissions. Only every 2 years to have to swap

Does your state have a visual inspection or just scan the OBDII?
If just a scan, you can remove your cats, delete the O2's and have them tuned out. You will pass emissions this way.
Other option is to gut the cats (so they are still visible), remove the O2s, and get them tuned out.
Either way, you'll need a tune, or need two different sets of cats if you have a visual inspection.
Removing cats will make the car louder.

i have the lm1 on my camaro and it sounds AMAZING. And it is LOUD haha. But, if you were to get LT's or an ORY forget about it, nothing but rasp.
