too loud i own a 99 trans am i just recently put pacesetter longtubes, pacesetter y-pipe, and slp lm1 exhaust on it (no cats) and its extremely loud. Almost a little too loud for my taste. My question is , is there a different cat back exhaust i could go with not so loud ?
Also i bought a set of bbk ud pulleys mainly all for looks. Will i feel a difference from these? Were these worth the money? And will i have to switch to a difference size belt?
thanks for any help

What were you thinking if you didn't like loud getting a uncatted exhaust with longtubes and a loudmouth 1? lol Switch to a magnaflow catback, they are quieter and still put good power down.

The only time cats REALLY hurt hp is if it's a dedicated track car that needs every last hp you can squeeze out of it. On a daily driven street car if you loose more than a couple hp having cats, then you have other problems besides them. I x3 adding cats first.
You could swap in a magnaflow, borla, or dynomax bullet in place of the LM1. You could also get a sweet thunder bullet muffler too.
I have the borla xr1 muffler and I prefer it over my brothers GMMG, which is said to be the best sounding. His has more rasp than mine does and he has a high flow cat in his I-pipe.

Catted Y pipes like the ones from Dynatech have been Engine Dyno proven to lose at most 1 hp on a stock 6.0L LS2 and maybe 1 or 2 more when moddeded with a heads and cam package.
The LM1 systems is just straigh pipe which may sound good if you do nothing else to the exhaust but as soon as you un cork it, it does get very loud. Also you can forget about a cam install as the sound just get louder.
I have Dynatechs SuperMAXX kit matted with a Corsa and a 228/230 cam in the car and its loud enough where I cannot idle the car in the neighborhood in the morning so I gotta start the car, immediately go down the road and let it warm up. The same exact exhaust system was on a 383 LT1 11.5 to 1 C/R motor with no Cats and it was rediculous.
But in the end its what you want and in most cases no one is at a level of performance where putting on a slightly more restrictive exhaust will make all that much of a difference.

Some people like louder cars though. Mines not loud enough for me. With cats and a 6 speed the noise is very controlable.
Yes sound is controllable but on a cold day, at idle, my car can wake up my inlaws and some neighbors and we are not that close to each other. So you gotta deal with what you can deal with.

Take off the CATS and throw a cam in there with tuning and you will get what you want.
