I'm new to the list (and the car) so forgive me if I'm covering old ground.

I've been told that Dynamax makes a cat back exhaust thats a bolt on
specifically for the Miata. Does anyone have any experience with this system?
 At around $100 (SCCA discount?) it sure beats anything from Racing Beat or
Millen. Is this price accurate?

I noted at Salina that just about every Miata was wearing 205/55 tires. I was
afraid of that wide a tire on a 5-1/2" rim so I had opted for 185/60 RSII's.
I am interested in what tire pressures any autocrossers may be running with
similar tires. On my first event with GAB shocks and the stock front bar
fitted with urathane bushings, I settled in on 26 psi (hot) all around. The
tires rolled over to the triangle marks on the side walls and the car felt
good (re: I won).

Any thoughts on an autocross alignment that won't totally destroy my street
tires?
