Long weedend, but productive. I already ordered the flowmaster 7100 for arctic cat off ebay and bought several stock 45's and 90's in 1-1/2, but was not liking the long sweeps on those fittings. Realized the "U" pipe I was cutting off the hushpower would fit my needs.
First, fabbed a new plate to replace the muffler spark arrester/exhaust pipe.
Next, cut the center of the "U" then cut a 45 on the female side:
This set up this combo pre-weld
This is the result all welded up:
The tight radius on the cut tube helps raise the muffler position, but is just low enough for clearance with the bed in "dump" position.
I still have to tweak the hanger ( and maybe add one to the other side) to get the unit positioned correctly, but that will have to wait until next week.
The result-- it is quieter at idle and low speed cruising. Istill need to fab a spark arrester, but i can easily reinstall the factory unit and run without the hushpower, but i'll fab or buy an arrester.
After new wheels, the eps install, and this muffler install all in one weekend--I am pooped! But what fun!
