washer mod is cost effective but doesn't do anything aside from slightly alter the exhaust sound lol
and the underdrive pulley is an absolute pain to install to gain minimal power.
long tube intakes, tp, cat back. should get you to 315~whp with a tune. obviously number depending on location, tuner, etc...
