Dual Exhaust

[dave]

I want to change the single exhaust to dual exhaust. the standard exhaust is 4 inches. I want to have 5 inch exhaust stacks. Any help with the conversion would be appreciated. Y-pipe, elbos, etc.

Hi Dave, and welcome to BMT.

Here is a post that might be of interest

the brackets from a junked R model will do the trick.

I "tried" the 5" pipe on my 673. Used a "racecar" style 4" in/out straight thru muffler and it about made me deaf!! It really roared in the cab.

I've since put twin 4" pipes and same muffler. It's quite liveable now, though not really quiet. Just don't get the drone of the big pipe.

To each his own, but just giving you what I went thru.

I made up duplicate brackets to mimic the passenger side. Just mirrored it over and bolted it on like the passenger side. Looks "factory". The only catch was I had to put a 40 gal passenger tank on the drivers side to make room for pipe. If you go with R model type brackets you might be able to get around that issue.

I could get you some pics of what I did if you like. I made my own "Y" pipe.
