How much more power should I be expecting with headers, catback exhaust, and hopefully a y-pipe? Then if I get some extra cash I'll be getting the XCal as well. My last dyno run was with a glasspack in place of the resonater and a cheapo glasspack like muffler at the rear.
without the xcal...i'd add about ten-12 horses to your figure in the sig..with the xcal..depending on the tune..prob about 19,20 something like that
