No Cats and Corsa=Rasp??? I'm about to get some headers and a new y-pipe for my car. I read up on it quite a bit and have just about decided to go with pacesetters for their cheapness. Well today I decided to see if I could find out anything about how they will sound with a corsa catback. It is looking like it will sound raspy without some high flow cats. I had planned on getting an ORY. Should I be looking at some cats too?

I think I would like to stick to the pacesetters. Anyone have any recommendations for a cheap way to get rid of the rasp? Would a bullet be cheaper than cats? How much different will the sound quality be between cats and a bullet?
pacesetters are good headers for the money, yes a bullet would be cheaper than cat and flow better... but i dont have any personal experence with a corsa cat back with a bullet in it... maybe someone else can chime in

I used to run Corsa w LTs @ ORY. It was pretty raspy from 2200-2800rpms, very raw and loud at WOT. Sounded mean at part throttle though. I added a QTP Catted Y and it solved all the above problems and really cleaned up the sound. It still roared like a beast at WOT. My muffler fell apart soon after and I replaced it. Corsa sounds different than any other LS1 catback but IMO the quality is not there for the price you pay.

I already have the corsa on my car. I put it on a month or two before my motor blew up about 3 years ago. I'm going to keep the catback and I'm definitely getting headers and a y-pipe. I was just wondering how bad the rasp would be and how I might be able to get rid of it. I'm also going to have a 238/242 cam with a stall (not sure what size yet). It's sounding like I'm going to need some cats though. No more votes for a bullet in the I-pipe?

I had Edelbrock LT's, ORY, and a TSP Rumbler. WAY too loud for me, WAY too raspy for me. I ordered a 344SC XL series muffler and catback from Spintech, and Had the Dynomax Bullet fabbed into the I-pipe. One of the best sounding exhausts I've heard on an LS1, very big block, only rasp I get is between shifts (M6) at 1/2 throttle, and it isn't near as bad as the previous setup.

Well I listened to some sound clips on ls1sounds.com again and I have decided to just get the Pacesetters with the ORY. I figure that if I dont like it then it will be pretty easy to weld in a bullet or get some high flow cats. I appreciate everyone's help and I'll make a new thread when I get it all together and let everyone know what I think of the setup. Thanks again.
