speed engineering headers and y pipe
not sure 1 3/4" or 1 7/8"
anyone fitted them with standard 1999 engine
(have magnaflow rear section and free mods and slp hood)
what results?
Would 1 7/8" loose a lot of torque?
thanks
Scott

Was thinking probably losing a touch of low down power wouldn't hurt performance as it would help grip
