Solo II rules dictate the cat. perverter to be in place.  I was checking 
on the system in 2.25" daim., which should at least help the top end a 
bit.  I wouldn't bother with a 2" aftermarket system unless it was 
mandrel bent which would probably help a little. (not a lot)

My thing is, I only have about 100-110hp to deal with and about 130k 
miles on the clock.  If that system, which I need a new one anyhow, would 
increase 3hp, I would be happy.  I just don't want to lose any throttle 
response, which I feel is more important for autocross.  The larger diam. 
pipes would help the hp on the top end at a big track though.

My cake and eat it too?
