If you just clamp it on you can swap it out between smogs.

Just cruising around under 2k it's not really loud at all, but give the gas and it's loud, but not any louder than some full catback exhaust I've had.

I also passed smog a couple months ago with this in california.

At my shop we had a guy going to the college in town and he was writing an ls1 camaro book, he had all kinds of sponsors giving him stuff to test. He was very thorough with his work. Every mod he did he would test. He tested 8 exh. systems, he would do each with the stock intake and manifols and then again with mids and cold air and so on. The best power made by an exhaust system that he tested was random technologies. It also fit the best out of all the kits we installed for him.

your going to here a lot of good things about magnaflow

good numbers, killer looks... I'd have to say I'm a fan. Although I do love the look of Corsa tips

[JRENIGAR]

^^^ agreed, corsa or borla both look good on ls1 cars.

If you can get a Corsa exhaust, if you don't like the price then go with a Borla. I always wanted either one, but didn't have the money so I bought the SLP Loudmouth I new for $350 back in '04. Borla was over $700 and corsa was at least $100 more than Borla. I had to get an exhaust, because I don't like the vacuum cleaner tips that the Z's have.

Ive done many different exhuast set ups through out the years, i really like the Hooker muffler, cat delete and exhuast cut out open. I like the deep sound to it but in the future ill go with some LT's and that will probably change up the sound alot.

i have the Loudmouth 1. its loud. its loud at idle. its loud while your driving and its FUCKIN A LOUD when you get into it. with the stock mainfolds and cats its not too raspy but when i cam it this winter i'm gonna havta change my exhaust around. otherwise it will be ungodly loud and i have a hard enough time getting a sticker already. i love the exhaust but like i said. it is LOUD
