    Default Y pipe for 98 k-1500

    I want to upgrade the exhaust on my 98 5.7 will a y pipe from an early90's truc k work on mine? Want to ditch the small pipe i currently have. If i remember right the early ones were 2.5" off the manifolds and 3" outlet?

    My 93 has the early style. I don't know if it will fit the later model. Probably just as cheap to have the local muffler shop fabricate what you want. If you want a DIY solution you will have to find a well stocked exhaust dealer and do a stare and compare. The Walker site definitely specs different parts but there is no dimensional information.

    it might not work. the 98 was a different motor as it was a vortec.. my guess is they are different from the non vortec motors
