SLP package
wrong sir..a catback and a lid will add 10-20 whp. the average dyno for a ls1 car... is around 300 whp.
The SS was rated 325hp (FLYWHEEL), the dual-dual (or CME) bumped it up to 335hp (FLYWHEEL), and the optional lid gave it another 10hp = 345hp (FLYWHEEL). But I wouldn't doubt it if would chasis dyno about 320-325RWHP (M6 car).
Peace,
Craig.
