hi all,
wat should be the best exhaust piping size for 4EFTE on stock internalls and stock turbo(CT9)..im goting for 3.00" inner dia will be 2.75"...dose it effects??
sugestions and coments by the senior members and all will be appriciated..
thankx
Stock turbo i recommend 2inch to 2.25inch, at 2.25inch diameter it gives plenty of room for future upgrades while still keeping torque levels up, 3inch piping is crazy on a GT imo, even the really high powered motors dont need 3inch piping.
