Where to get high flow cats?
The car has no cats, and is still way too loud with the headers. Where could I get some cats? Thanks.

PLEASE keep it simple: Go to ebay and purchase the high flow cats here: http://cgi.ebay.com/ebaymotors/Thund...Q5fAccessories
I did and the rasp is now under control and runs excellent!!! Remember, the LS1 likes a little back pressure............

Two things:
1. Watch out linking to non-sponsors- that's a no-no in these parts.
2. Those cats are okay- those were the ones that came in my catted Y pipe and I hit a rediculously tall speedbump which barely dented the cat. Because of where it hit the ceramic broke loose inside the cat. I'm having to gut the cats because the guy who made the pipe has now fallen off the planet.2000 Pontiac Firehawk #0041 of 742

Oh......My bad everyone. I was simply trying to help this guy out with the setup I experienced from ebay. Sorry about that.........
Oh and 67CamaroRSSS.....you may be correct on your point there; I read on a Camaro Magazine article and other reads that the LS1 likes some backpressure. You would figure people who have experience with our vehicles would be correct, especially if quoted in a magazine LS1ers read. Perhaps not. But hey, what do I know, I just love LS1's!

I bought my cats from these guys and they were great to deal with!
I did in fact go with the slightly more expensive metallic content cats they sell as i had to ship to the UK and i just wanted a more sure result if i should hit any bumps. They fitted fine and i would recommend them !!

I've had my wrist slapped once before for linking to an eBay seller, so just a heads up. (sorry, no "wrist slapping smilies available!)
All cars like a little backpressure to create low end torque. Too little backpressure on a street car and all your power is towards to top of the power curve. You're both correct- top fuel cars produce tons of power but stay at the top of their power band through a run. Typically normal street driving you need power in the lower and middle of the curve. That's where a cutout comes in. Not just for the noise factor, but to shift the power band when you drag race. The problem with stock exhaust is that it creates too much backpressure and doesn't allow the exhaust gasses to escape fast enough. This chokes the engine and lessens the power it can create because it doesn't get enough clean air/fuel in the combustion chamber.
Think of it like a straw. If you try to drink through a coffee stirrer, you'll exert a whole lot of energy to get very little soda. If you try to drink through a 2" peice of PVC pipe you'll never get the soda up the straw. It takes just the right size straw to get the optimium amount of soda with the least amount of effort.
At least thats the way I've always understood it.
