Well, your gonna get this from a lot of people but i'll start. Mostly everyone on here will tell you that this exhaust sounds GREAT on a stock car. However, once you throw on a set of LT's, or an ORY, it turns loud, annoying and raspy. Now if you want loud, I say go for it. Pass emmissions? Nope
The catback itself doesn't have anything to do with emissions, I passed easily with loudmouth and stock manifolds and cats.
I currently have LT headers, gutted cats, and the loudmouth and yes, that's about the loudest exhaust around. I would not recommend it for a car you're going to drive everyday, but I only drive mine a few days a week so I don't mind
In all honesty, when I open it up it just sounds like a race car and I love it and you can hear it far away.
Feel free to ask me any questions about it. Good luck with whatever setup you decide on.

thats all this exhaust with Longtube headers is...NOISE!!! if you want the loudest EXHAUST out there....id say corsa LT's and ORY or gutted cats....LT's ORX pipe and Flowmaster 1 chambers or some straight through mufflers....THATS a LOUD EXHAUST!!!....SLP loudmouth is plain LOUD!...longtubes will cause you to fail the sniffer/visual emissions check if they do it in your state (where you from?) it has nothing to do with the catback itself....it hasta do with your SES light really if you ahvea bad 02 or no 02's then youll have a problem cuz itll go on (youll need 02 sensors and bungs, 02 simulators (recommended with cats) or CAT DELETE form LS1 edit of the 02 sensors) that is if they do not do visual/sniffer check...LT's will amke any exhaust loud!!!...i say if you can get LT's (your state or county should only haveta do the OBD II= On-Board Diagnostic 2 test scan for codes thhat will allow you to pass with LT's(SES light cant go on to pass) get a GREAT catback and run Pacesetter, Jet-Hot, or QTP lt's with the QTP catted Y or the dual cutout Y then jsut open the cutouts...for EXTREME LOUD....and if your gonna haveta run cats...the get a cutout on the I-pipe of the cat-back

Sorry dude, I think every gets kinda tired of answering exhaust questions. LS1sounds.com is your best friend. you can hear how shitty a loudmouth sounds with lt's and ory pipe. with cats, its not too bad, still sounds like a pick up truck to me though.
Take al isten to dual cutouts as well. you want loud...those are loud as hell, and if you are forced to go on a long trip you can close them up, save some gas mileage and your ear drums.

Sorry bud, but they sound like ****. I've had the setup, and I didn't drive my car for 3 weeks because of it. The thing sounded like a pickup with burnt out glasspacks..
Glad you like yours, but 9 out of 10 people here will say it sounds like ***.

i had the LM with my headers and ory and as much as other people liked it, it was just way too much for me to drive everyday. i switched to a hooker catback and couldnt be happier. still sounds mean, its still pretty damn loud, and i can hear my radio over it without blowing the damn speakers. my resonator from the LM is still in the i pipe though, so i dont know if that makes a difference

I had LT's/ORY/LM. It was loud, and sounded great at idle and above about 2800 rpms. From 2200-2800 it made me want to puke. It was a very flat, flapping kind of wierd noise better known as rasp.

I have Mac mid length headers with cats and the LM exhaust and I don't think it's to loud. As a matter of fact I've had nothing but compliments.
The old school cars with iron blocks and flowmasters are much louder.
