4-3-1 slip on mid pipe video & sound clip 4 Months, 3 Weeks ago
Finally got it to post! I was able to take it for a ride today and do a little testing. I am running it with UFO fuel programer (probably on the rich side) Stock air filter with modified air box. Felt very good. Better with muffler off. So sure I need to increase muffler size to 2.5" inlet/outlet

I now know that I have room to fit in a 4-1 collector based on this design with out losing any ground clearance. It will have to wait though until I get some cars fixed around here

Oxygen sensor is located in final collector so reads all four cylinders. A cone will be added to the out let of this pipe to bring it up to 2.5" outlet size and allow for larger muffler.

First step was building a 2-1 colector for the rear cylinders.

Second step was to merge 2-1 collector for rear cylinders into a 3-1 collector with the front cylinders.

So it breaks down like this:

Two 1.5" stock rear header pipes are merged into a collector with a 1.75" outlet.

Two 1.75" stock front header pipes are merged into a 3-1 collector, with a 2" outlet, along with the rear 2-1 collector.

Final outlet size for the muffler/can will be increased to 2.5"

Now this design has some real power potential. Just look at the angles into the collector, this thing will FLOW. And a sound reminiscent of a Gen 1 4 into 1. Can't wait to see the dyno sheet. Great work! AJ.

Very nice work. Sounds great. The guys that have done the most work to their bikes all seem to have pictures/videos of their bikes in the snow. Burrrr! Hope the snow is gone soon and you get to put many miles on it soon.

Every time I build one of these it gives me another idea on how to improve the design. I have at least one more design in mind. I know now that I can fit a 4-1 collector under the bike with out causing clearance problems. It would look very simmilar to this 4-3 system.
I had the basic design on paper before the 4-3 but then started having doubts about clearance. Plan on going back now and working a little with the original design.

It's surprising how easy it is to piece together your own system with pipe and a hack saw when you build the system on the bike.
