absolutely. your exhaust can only flow as good as its smallest opening. the header primaries flow better than stock, and your B pipe is opened up another 1/4" from stock. it'll have some buzzing to your exhaust sound when it's cold, but you will definitely notice a low end torque as well as high end difference with a 4-2-1 header.
