exhaust in cs
exhaust in cs
I was looking over the rule book and saw in section 13.10 E that a cat back is legal in stock. Am I correct? Would really like to do exhaust on mine, but have not because I thought it would knock me out of cs which I would like to stay in this year.

Re: exhaust in cs
If I recall correctly you can do cat back, front sway bar, air filter, tires, ... hmm, can't remember the other big ones.

That's certainly how I read the rule. However, the exhaust system must meet sound control standards [3.5]. But anything that is street legal will probably not be too loud. However, note that the Event Chairman has blanket authority to declare a car is too loud.

Shocks (separate reservoir shocks are probably going away), wheels (must be same diameter, width and offset within +/- 0.25" as the stock rims), crash bolts to adjust caster and camber if they're in the FSM, fenders can be rolled for tire clearance....EliseAutoXr wrote:If I recall correctly you can do cat back, front sway bar, air filter, tires, ... hmm, can't remember the other big ones.

Re: exhaust in cs

Are you sure about that? I haven't looked at the rules lately, but I don't remember seeing this.

Re: exhaust in cs
Yeah, first I heard of the fender rolling thing in stock. I think SS was lost over that protest in recent years.

That will teach me to work from memory. "13.3G Tire must fit the allowable wheels and fender wells without modification."

Re: exhaust in cs
I don't recall anything about fender rolling in stock or "street". Exhaust systems will likely have to exit in a stock location in the future for "street".

Re: exhaust in cs
I have a K&N filter for the stock airbox for your car I will let go cheap. It probably had less than 100 miles of air sucked through it. Still looks new. PM me if interested.
Re: exhaust in cs
I believe iv already got a k&n. If not I'll pm you
