    I had a MAC ORY on my old '99 Z28 as far as quality it's a good y-pipe but.....I can't really say it helped my car all that much...made it much louder but sometimes that's not a good thing (got a ticket not even a week later).....in the 1/4 mile my car picked up about 1-1.5 MPH on top end but the same ET's. I will not be putting a ORY on this car I'm trying to save up and purchase some LT headers this summer I'll most likely put a cat'd Y on this car.

    Why don't you do away with that stupid Y pipe and go with over the axle true duals?
