If I was to put on jdm headers on an ls motor, would i need the gasket and flange or do I just need to modify my pipping and/or collector end…? Yes im stupid
u can’t really use type-r one piece headers… the DA’s won’t have enough clearance to make it fit… only way is to trim down your front crossmember or replace it with a aftermarket crossmember… and the type-r headers fits fine but u will need a new cat/test pipe that is 2.5" inlet…
