Four into Two Exhaust system
« 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.

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
