Finally got all the parts in and got back home to check the fit and lineup of everything...

Stock exhaust was 1.125" tube.

I will be reusing the stock flange because I don't feel like trying to replicate it in stainless right now.
I bought a little shorty glass pack off ebay meant for motorcycles. It has 1.5" inlet and 1.75" outlet (reversible actually) so I came off that with some mandrel bent 1.5" stainless sanitary tubing then a 1.5 X 1.25 weld reducer. That's as close as I could get to 1.125 but there is a little space on the flange to play with.

I hope the lack of back pressure doesn't cause any problems.....

I have to wait for my heads to come back from the shop before I can start cutting it up and welding it together. The glass pack is chromed steel so it will probably rust to shit in a hurry just like the stock exhaust, but it's pretty cheap to replace. I thought about having it duracoated at my local gunsmith but I don't think it would be worth the cost.

It should come out of the back of the head on the starboard side, 90* to run across the back of the engine perpendicular to the plane of the engine shaft, and exhaust straight out to port. The glass pack has a little bracket on it already that I plan to modify to attach to the engine block to stabilize it. I might add another to the top of the top pulley / belt cover if it looks like the vibration will get to it.




I will post pics of the finished product when it's up and running.....

Nice!

Thanks...... mf'ers gonna hear my white trash express coming from 20 miles away with the glass pack. Like Joe Dirt in a mudboat!

Haha!
