This episode of Vincent Shorts we reach out to Cam over a Baggers and Bourbon. He had a video on his YouTube Channel that had a lot of good points he made on exhaust.
I just wanted to reinforce some of the things that he was saying and maybe give some explanations as to why we do some of the things that we do.
One of the things that you talked about was the heat that was developing from the pipe.
First, let’s go over our pipe, why we do what we do, and then go over a pipe in the configuration of what Cam was talking about, show you why we do what we do as we set out with this exhaust pipe. It was going to be a FULL RACE SYSTEM.
The rear primary gives us heat problems on these V-Twins. The issue is this area of the pipe near your knee really radiates a lot of heat onto the rider. The reason that we designed this on the V-Twin is in order to make the front pipe and the rear pipe as close to the same length as possible.
What we did on this pipe is we swung it forward and then back in order to provide a good smooth transition and to get some extra length into that rear pipe. Getting the two primary pipes in equal length is really the best design.
We come straight out of the head. We have approximately a 90 degree turn out, then a 90 degree turn forward, and a 90 degree turn back to the collector. The gas is actually turning 270° to get to the collector.
We have another pipe that we also manufacture for a customer, and it really does have that design that I think that Cam spoke about. Where the pipe exits the head down instead of out. A 45 degree bend down. We sweep forward 180 degrees. We sweep back 180 degrees. The pipe is out of the way away from the rider. It’s a great design making the pipe longer but it is also turning 405°. Each of these turns, the more degrees of turn that you have, the more drag losses that you have in the pipe. The exhaust exerts a thrust onto the outside of the pipe and the pipe is pushing back. That does not lead to the best performing pipe. Now, from a comfort standpoint, much better idea. This pipe does make very, very good power but not the best as our NhB systems are designed to do.
Should we come out with a pipe like this? I think that might be good, especially for all you guys that ride to the track before you actually go race. I mean, this would be very, very good.
We do have an option of a system that we call the Mark 1 or Mk1. We haven't really promoted this pipe very much. It’s a pipe that would more cater to that rider that wants to ride a little bit longer and lose a bit of the performance.
You may notice out of this pipe, is short. It's nowhere near as long as as the front pipe. So that was a compromise. And I guess there's a reason why I haven't really been excited to promote it. It is an option for people who maybe want something a little bit more comfort, and with a reverse cone megaphone muffler.
The Mk1 has that same, Burns Stainless DNA, but it's, it's not a no compromise NhB-No Holds Barred pipe.
Thank you, Cam, at Baggers and Bourbon for giving me the opportunity to respond. Thank you so much for bringing up those great points in your video.
We are listening to you guys and I really appreciate what you're doing out there. So, until next time, this is Vince from Burns Stainless.
