Heddman Headers?

86GT · 01-30-2001, 04:40 PM

I was wondering what H-pipe can I use with a set of Heddman full length 1 5/8" headers. Do I need a custom H-hpipe or would any aftermarktet piece work?

I'd think just about any aftermarket H-pipe should fit...as long as it's for long tubes.

Just anyone won't fit, because it uses a 3 bolt header flange. When I had them I couldn't find a h-pipe for them so I took them back. I here that headman makes one but have yet to see it. How ever there is a ad in MM&FF and they had a 3 bolt h-pipe but it was 3" and kinda pricey. Good luck man!

Luckily I haven't bought them yet, I wanted to see what I'd be getting into if I did.
I might just go ahead and get the MAC longtubes then...
