ive got 1.8 YT's with everything sitting around and I wanna put them on the car, would that hurt the car being on stock exhaust manifolds? I have no money to buy teh headers at the moment
no i ran 1.9 modded stockers on stock manifolds with 3 in dp for 6 months or so and ran like a raped ape i had a stage 2 ic though to but that makes not difference.
I was thinking the same thing...I mean its just letting more out so no chance of boost stacking but im still gonna be on the stock pulley until I get headers
the buick regal gsx stage 3 came with high ratio rockers and a 3.5 pulley with a catback..that car was still on stock manifolds so its gotta be fine IMO
