no catalytic convertors (filters exhaust so its clean) the stock ones are restrictive, so alot of people take them off or run higher flowing cats. they are on the pipe that merges the two off the headers into 1 single pipe. (Y pipe)
that has many many videos already of this exhaust. this is only my second mod on my car i didn't buy it too long ego. right now i have a lid and exhaust. probably go tint next, then p/p tb and then some nice z06 wheels....can't wait!!!!
If you get the borla you wont regret It. I have the 3inch borla adjustable cat back. I Now have long tubes and a y pipe which makes the car sound really good in my opinion and pretty loud. I would venture to say it is up there with the top set ups for noise level.
When you order the kit it will not come with cats. You will still use the cats on the car. The kit connects to the mid pipe which is in between the end of the Y pipe and your muffler. Good luck with your modding.

I've got longtubes an ORY and the I-pipe for the loudmouth that I turned down and to the side, that SOB is loud! At WOT it sounds like a circle track car. I will be switching over to the hooker exhaust system soon which should quiet it down. I think the LOUDMouth sounds the best on stock manifolds and I love the way it sounds with Longtubes and ORY but I don't need anymore tickets, I have paid the state enough money
I just installed the SLP Loudmouth II catback on my 2000 SS vert and it sounds awesome. Nice and throaty w/ a mean growl as RPMs increase.
Loud - but not obnoxious. And, it's SLP which has history w/ the SS.
The Loudmouth II, as most know of you probably know, comes w/ a muffler, instead of the resonator, which is found on Loudmouth I systems.
