camaro 22

Ok, I dropped my car off at the shop tonight, and tomorrow they're going to install my 3:73 gears, 3200 vig torque converter, and a tranny cooler. Now, I don't have any cats on at the moment, but after doing some searching on here, it seems that an Lt1 with lt headers and a borla sounds better with a cat. I have a catco high flow cat, but they said the only way they can get it to fit is if they cut my borla back some. He said for me to think about it over night, and let him know for sure tomorrow. Would you guys cut the exhaust to put the cat in? Would it really make my car sound better, hopefully a smoother tone as well? I mean I like the rumble it has in the lower rpm's but when you get on it it becomes raspy and higher pitched. Also I'm running the borla with no plate. Would it sound better with a plate in? What are your experiances with borla's and LT headers? TIA

if you want a cat just cut it. The cat will clean up the sound some but it will make it noticably quieter.

I know what you mean about the borla being raspy with LT's and no cat, mine were as well. I had my shop take the piece of the borla pipe out and make a new piece of pipe using their own stuff and weld the cat to it. I kept the borla piece in case I ever wanted to sell the complete cat back system. Just to let you know I used the dynatech powercat and it got rid of all the raspiness and I couldn't tell that it got any quieter either.
