My cats are shot. I am thinkin of making some exhaust headers and running a dual 2" exhaust. Wanna make a cancellation, resonator, and 2 high flow mufflers. After that i wanna UD the accessories and OD the idler and blower pulley. Its a '94 stock except it has a cold air intake. Summit offer an UD kit pretty cheap. Is it ok? How much more can i spin the blower? I'd have no problem puttin a FMIC in. The a/c condenser is gone already. And what kind of gains would i get? Any advice would be appreciated.
 
with stock heads, tb, and maf not much gain will be seen. the biggest you want for sc od is 10%, it will work better off of only 5%. overdriving the sc with stock heads promotes head/head gasket failure.

as for the ud pulleys, all i know is the pulleys scp offers are nice.
