numerous companies have 200 cell HFC's

Either get at least 200 cells, which still might trigger a CEL every now and then, or nothing. You can see thru them, and pollute a bit less, but exhaust will still stink. Don't understand why people do that for a handful of HP difference when most women refuse to ride in such cars, but to each his own.

Akra or Challenge

Most aftermarket cats are 200 cel.

If you are going for 100 cel cats, I would suggest the Akrapovic eVoloution system. That's what I run on my car and I am very happy with it, especially the quality.

The car will only smell at startup with 200 cel cats. You won't notice any smell at all once you are off and driving. Just to correct captain misinformation elp_jc.

Might as well run with no cat....

I just saw a car with an Akra EVO, and it had no smell while I was standing next to it.

I saw one with Akra the other day running and did not smell anything bad. Anyone here with an Akra have any issues with smell?

My Akra Evo smelt only at cold start-ups and when the car was running reach to warm up cats.

You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
