Car Sound Catalytic Converters

[Mystic350]

Does anyone here have any experience with Car Sound Cats? I'm looking to make a Hooker LT/Mufflex ORY-pipe a little bit more emissions friendly and was directed to Car Sound (Denny of Mufflex variety suggested them). I found a 3" cat (Part #14109, listed as OFF ROAD USE ONLY!). I'll call up Car Sound tomorrow to find out what that means exactly, but I'm assuming it doesn't meet some federal regulation(s).

Has anyone used Car Sound cats with a H/C car and gotten through emissions? I'm running a LT4 Hotcam and have passed emissions in the past through stock exhaust.

Thanks,
Chris

Quick follow up, Part # 94019 is listed as "EPA OBDII Compliant". They are both 3" in/out, I'll find out what the differences are from the manufacturer tomorrow and will post what I find out.

Well, for one, anytime you actually MOVE the cats, it becomes illegal. So longtubes = illegal. But just having cats will greatly benefit a private inspection.

I actually have a pair of unused carsound/Magnaflow 3" cats that I'm selling. PN: 53009ca. (PIC)

My bet would be one is CA legal and the other is not, but other than failing a visual check, dual 3" cats should have no problem cleaning up an hot cam.

Tough part will be getting them close enough to the headers so they can get to operating temp and work efficiently.

I guess I'll get the car through inspection after August 1st with the new changes in place. Then I'll get the new exhaust on and hope that 2 years from now it'll be clean enough to pass the sniffer and that the inspector doesn't know where the stock location for cats on a '97 Z28 are.

Dead, why are you selling those cats and how much do you want for them?
