Title: Four into Two Exhaust system
Post by: r1_pete on February 21, 2018, 07:14:46 PM

Does anyone know of a maker / supplier of 4-2 exhausts. I’m using a 392 engine in a 71 chassis, so would need K6/7 exhausts.

Ive a few sets of headers, 4-4 and 4-1 so could make my own, but re chroming would be as much as aftermarket pipes.

Are you looking for used or new? I have a set of US Jardine 4 into 2s..... can take some better pics if you’re interested.

They need a good clean to fully asses the condition of the chrome, but they are solid.

Be aware they will NOT fit straight to a 392 (F1) head, you will need to remove your exhaust studs, and then fit a set of K0-K6 exhaust stubs before those pipes will match your head.

Cheers, yes if they are K4 they wont work on my 392 head.

Thanks for trying though.

No worries..... to be honest, I didn’t like them when i first bid on the bike....but they’ve sort of grown on me and i may just keep them for an alternative to the delkevic.  :D

Try CycleX but they'll cost you especially with import tax
