Im still waiting for the header to get here from Perrin and the gaskets to come in at the dealership. Thx for all the suggestions. Im new to Subie ownership. My other car is an 05 Vette with 452rwhp. It has heads, cam, valvetrain, ram air, headers back, ported and polished oil pump, ported intake, ramair and Hurst shifter; but is dull in normal driving and scary fast over 4500rpm.
