Does anyone know if any of the exhaust manufacturers are planning on making a high-flow cat set up? I added a Bassani high-flow cat x-pipe to my Cobra and it yielded 15 rwhp. It sounds to me like that is where GM is getting most of the extra power for the '02 Z. The Bassani x-pipe for the Mustang eliminates the pup cats and replaces the other cats with two high-flow cats (while my Cobra had four cats, a Mustang GT has six /phpBB/images/smiles/icon_eek.gif). I could feel an immediate difference and it never triggered any codes. Lots of companies made it for the Mustangs, I can't understand why they wouldn't for Vettes, especially now, given the change in the '02. There will be a demand created by '01 and '00 owners wanting to dump the restrictive pup cats. Anyone heard? BTW my former car passed the Maryland treadmill emissions test with the Bassani system and I believe that it was 50 state legal, so I don't think that would be a problem if anyone is curious.

I am also curious. Especially now that the general has done away with the pup cats for 02s. There has to be a great market out there for a manufacturer who is interested.

Random Tech offer a high flow cat and "X" pipe set up. "Our C5 converter/X-pipe assembly is available. It sells for $839. The part numbers are 952720 for 1997-1999 models and 952721 for 2000-2001 models". I guess I am allowed to post prices. /phpBB/images/smiles/icon_razz.gif

Hey Carl, how many cats does it have? Is it stainless steel, one piece, a direct bolt on, and emissions legal? Is there any warranty and will it throw any codes? Thanks. /phpBB/images/smiles/icon_biggrin.gif It seems pretty expensive considering the Bassani cat pipe was $450, but then again what isn't expensive for a Vette? /phpBB/images/smiles/icon_frown.gif

Scott, that is to bolt on from the exhaust manifolds and includes 2 high flow cats at 3" dia back to an "X" pipe and that will bolt to the flanges, I do not know how many pieces it is shipped in, and it is suppose to be direct bolt on. I have been told it is a stainless system but I have not seen it in person yet.

Give us a post on the forum after you check it out, that is something I am interested in. Thanks. /phpBB/images/smiles/icon_smile.gif I generally don't like to be the first one, unless its free of course. /phpBB/images/smiles/icon_wink.gif

Hey Carl, I still would like to know. What cat-back are you going to be putting on the new car? /phpBB/images/smiles/icon_smile.gif

Scott, whatever one I get for free, no just kidding I will be using B&B oval or round tips, I have to see how loud the new engine we will build will be with long tubes before I know if I am using PRT's or the standard sports like I have now.

I've spoken to Random Tech about this cat setup and it doesn't really add any horsepower on a stock engine...so unless you're doing major mods, I don't think it would be worth it.

Brian, you are correct sir!!! If your adding header and intake you will pickup probably about 10-15 hp because the Random Tech cats flow about 250 CFM more each I believe, if you do an engine or heads and cam with the above you will see a much greater increase. /phpBB/images/smiles/icon_smile.gif I think these cats are 3" in and 3" out as well, correct me if I am wrong.
