I looked on the site and all I could see was mustang propaganda. What am I missing.

Thanks :confused: :cheers:

From what I understand it fit & work in the C5. Many CF members have used them in their car.

FWIW, some say C&L and Carsound are the same.

Do I call them for my application. I havn't really seen any horsepower claims with any of the highflow cats! I will have TPI long tubes, donaldson and SLP loudmouth. If there are not any gains with the high flow cats, is it really worth doing?

Anyone who know please answer. :cheers:

Gains depend on mods. I'd expect 8-10rwtq and 0-5rwhp.

RT Cats are definitely the most expensive.
Mostly moot point for 90% of the exhaust/mufflers out there.
RT might be a hair better but the $/hp or tq for that matter isn't there.

I am. Yes, 2.5" per side. I welded the TPIS H-Pipe directly to the front of the cats. Like most aftermarket cats you'll need to tilt them at a slight angle when fitting. Maybe lke 15* or so. You'll also want to trim the flash around the edges of the cats. A good exhaust shop will know what to do. Also welded them together in a spot to reduce them rubbing/vibrating against each other.

I didn't see any gains on the dyno, but I raced a friend with an '01 with the same mods except for the cats (he had stock cats,) and I actually pulled him through 3rd gear before we got out of it. Here are some pics of my install.
