What would be your choice?
I got the new exhaust installed on the hack last night. It’s a MAC 4 into 2 setup that looks close to stock.
I was hoping that it would be quieter than the ProSport 4 into 1 that was on the bike when I got it.
I don’t think it’s quieter. The exhaust note is deeper and more pleasing to my ear, but it might even be a little louder than the 4 into 1. (Not that I don’t like a nice sounding kind of loud exhaust note – but it’s right next to the sidecar passenger.)
In any case, the bike runs better now. There was a huge flat spot from about 3500 to 5000 (right in the 5th gear crusing range) that is now gone. The bike used to have trouble accelerating from 55 to 70 and now it just goes.
It also feels like there is more low-end torque available, so I can short-shift it in town and cruise in 4th to keep the noise down.
So I went from a raspy, anemic sounding, power robbing exhaust to a (maybe) louder, deeper note, power giving system.
I guess that’s a gain.
It will be interesting to see what happens to the MPG. I was getting about 27 MPG. I need to fill up this afternoon, so I’ll know in a few days.
The best part was having to beat on the side of the exhaust cans with a hammer to make some clearance room for the axle.
Thus again proving that all aftermaket is junk.
