Any Real high flow cats?

[2GturboTALON]

I was wondering if anyone makes a real high flow cat that bolts up to aftermarket exhaust?

Could you more specific about what "real" means?

I think he means a Highflow CAT that functions like a CAT should.

I have one in my car. Its a nice slip fit unit, been in off and on for 2 years. Passes my local, strict smog laws easily with my big squirters and Whinebro.

And its big all the way thru. Not necked down inside and just flared to fit 3" pipes either.

I have a Catco high flow racing cat. It cleans up the exhaust well, but still stinks insted of burning your eyes and throat It starts out 3"gets bigger inside all the material, and back to 3" outlet.

Magnaflow (high-flow) converters. It says it right on the box w/ a little graph underneath that compares it to the flow of a stock cat.

Probably not a straight bolt on but one of the best available:

Random Technology

Im using the RRE HF unit that bolts to their downpipe. I have to go for the emissions test this summer so I guess I'll find out if it actually works

yup. i got one of these, but i think the biggest they make is 2.5", or at the time i got mine, it was the largest. i have easily passed 2 state inspections with it. all i had to check it out at the time was 2 other cats, one was a new catco, and the other was a catco that had been used for a long time. holding it up and looking at the sun, the random easily let the most light thru.

I put a Random Tech 2.5" on my Talon last year and when I got the emissions done the mechanic was amazed at how clean it was (I've got a lot of engine mods). He said the results looked like they were from a new car.

Keep in mind like i said "Bolts" up to aftermarket exhaust.

i have a 91 vr4. the random cat had the flanges that rotate 360 deg. on both ends.
