Okay so i really want a 4-1 header for my b18a in my 92 teg but im not so hot on the idea of notching my crossmember but i found this header from weapon r and its a 4-1 for a 94-99 ls would that clear the crossmember, anyone have this header installed? thanks.
you still have to notch, but you dont have to notch much, its like an inch if that on one part to clear one of the tubes
