Hey iv got a 1990 blazer 4.3 4x4 with hedman headers sitting in my garage waiting for my poor a$$ to have the cash for a custom y pipe. I already have a magnaflo hi flo cat and a flo master delta 40 sounds pretty good but I have some leaks in the system.

Has anyone put these headers on a 4x4 they are supposed to fit, how did they sound and how much money did you guys drop to get the y pipe made, or is there some other y pipe that can be retro fitted to work,

thanks

 

Are they 4x4 headers or 2wd?

 

they are 4x4 ones they say they should fit on summitracing but I was wondering if anyone has put them on a 1990 blazer to see how hard they are to put on. there doesnt seem to be a lot of room i dont know if ill need to lift the engine up to get them in or what
