do you have to have a cat to run in street prepared?

From my experience since the class says "street" you should have one. Don't take my word for it, check out the rule book......


Stock or not.....It's Still a J !!!

"Exhaust manifolds and muffler systems are free, except that they
must be quiet and terminate behind the driver. Exhaust heat
shields may be removed. Rear- and mid-engined cars without
exhaust headers/manifold systems may use any exhaust system
that meets the requirements of 3.5. This permits the removal of
“heater boxes” in order to install headers on such cars."

So your answer is no, you do not need a cat.

You ask that question, and ironically enough, the LACK of a catalytic is what put my Fiero in street prepared...

Just ribbin ya!

But Zach's right.

For future reference, go download a copy of the rules from www.scca.com

Click on the "Solo" tab on the left then "Cars and Rules"

Sleeper style, they don't see it coming that way.

ok thanks, i read over that section, i just wasn't really sure if the catalyst was included under "muffler systems"
