Which long tube headers are people going with for gen 3 truck motors in a g body (87 GN) without modifications needed? I have a 5.3 DBW motor that I would like to go long tube headers with, but I do not want to make modifications to the frame rails or suspension. I do plan to eventually swap the suspension arms to tubular (assuming it would give me more clearance). I was reading other people used Hooker Blackhearts and Hedman, however I do not believe either of those options exist anymore.

Also any advise on which X pipe or H pipe to go with?

Thanks

 

I’d look into Speed Engineering to see what they offer. They are typically the best bang for the buck with good results.

 

Thanks. I ended up ordering their 1-7/8" LT headers, hopefully they don't require too much massaging to fit with my LM7 in my 87 Grand National.
