LBR There's the answer from Eddie himself, what a shock. Those 2 headpipes are not equal length, as in exactly, but very close. What he doesn't realize tho is the fine tuning that we do have to our avail....LBR

To Answer your question.

Yes the pipes are pretty close to equal. They would be with in a inch or so.

You really want the pipes as close as possible. With the pulses not going into a 2 into 1 type pipe it is not as critical to be the same. We can make adjustments with-in our fuel maps, trims, intake runners etc... Then you can just run it on the dyno and make each pipe to where you want you power and what work best. They may not be the same in some cases.

You guys really don't have that option with all your stuff or Ign/ Fuel system settings.

I hope this helps.

Eddie

Subject: Question on exaust


We are having a discussion on a Rhino forum (of all places) about this particular exaust system on Eddie Krawiec's bike being equal length headpipes - can you elaborate? It does't visually, but the rear pipe could be longer than appears ....It is the picture on post #27...Sorry for this inconvience, but we're in quite a discussion about it...... Thanx, Lance Rowland

My honest opinion is that we leave all the R&D in Muzzys hands as they are professionals and make the best exhausts on the market!

I believe that the front head pipe needs to run on the drivers side of the engine as to keep it away from the clutch cover. There is three times the room to work with on the drivers side!

Routing the front pipe to the drivers side is nothing new. I had my front pipe run under the drivers seat after my engine cover and and passenger seat caught fire. .I took it to a friend who tunes pro stock and super comp cars....he looked at the looped mess on the rear cylinder and started laughing ....equal length on something like this is a fucking joke. His words exactly LOL Austin Coil were not....in the end my front pipe wraps the drivers side around the back rear pipe is about 9 inches long meets up with the front pipe and into a muffler....less pipe less heat. I do know that my machine is running pretty sweet 2 people and 60 on the sand is not bad at all.....

It really is laughable that we would think about something like this on such a crude machine

A Rotax is not a Harley but they are both twin Vs my front cylinder pipe on my Harley is almost a foot longer than the rear.....I"ll give Willie G a call and ask him Whad-Up

In all my readings on this swap, the exaust seems to be a big thorn in the butt for swappers....this will be another step to get closer to "Rhintaxing 101"......LBR
