I need a 3 inch cat for my GLH.

I need to pass AZ smog. Is car-sound a good cat? Good as in low emission.

Never again with catco.

It caused me to fail smog in CA. Never again will I buy catco.

I purchased a Carsound cat off of ebay for less than $40. Since Carsound is manufactured by Magnaflow, it's of decent quality. Plus it has provisions for two extra o2 sensors, if I wish to add a wideband later on.

I passed emissions in KY with flying colors with a 3" catco.

Walker Super cats work great, :nod: and I even think our vendor, Racing Solutions sell High Flo cats.

why did the catco cause yours to fail?

I also run catco's on both my daytona's and they both pass emmisions, even the the one in my 84 'tona, which is 3-4 years old still passed, it just barely passed but it did.

You asked me a question I have no answer for. I'm not a chemist.

All I know is that the *less than 2000miles* catco failed while the walker cat passed.

Could be an O2 sensor issue, which caused my new cat to fail.

Like I said before, the only thing changed was the cat and it passed with the walker but not the catco.

I will not buy a catco ever, and that's final.


Looks like Carsound it is.
