Paul Bryant full system for 2.5 R3

Gimlet · Jan 23, 2025

@Paul Bryant how's this coming on? Are you taking orders and have you any pics/details?

I tried sending a query via the Viking website but couldn't get the message to send and the Facebook page was "unavailable".

Very interested if it's ready for sale.

I have one on order, I think number 1 (for sale to the public, non prototype). There have been a couple of setbacks but things are back on track and when I get a finished product I will let everyone know the results. I hope to have it in my hands in about 2 to 3 weeks.

I know it's rude to ask, but how much was it? His work is top notch- very eager to see it when it come in. Thanks

I asked them about the size of the headers, and it turned out to be smaller than the maximum possible size. so I fabricated mine, which is 2 inches right at the exhaust outlet port, but theirs is smaller,.
With my headers and slipon, after adding fuel and remapping ECU, this Rocket has become something else

It would be great to hear an update from Paul, either on here or his website. I'm guessing he's got an awful lot on his hands right now but there is considerable interest in this system and a lot of potential sales.

Maximum possible doesn't necessarily mean optimum. How did you calculate your header size and design, or did you simple fabricate the largest diametre that would fit the ports and if so why?

Genuine question. If I can't find an off the shelf system I may look at custom-built but I'm trying to figure out the dynamics off gas flow on these engines for optimum road riding perfromance.

Have you got it dyno tuned yet? How did you add fuel? What afr are you running? How was engine heat affected and timing?

Dyno numbers - 2.5inch Headers vs Stock headers

Dyno runs charts are 2 years apart. Both Dyno are from Different Businesses. Not the same Dyno machine. Dyno1 was ran during Summer July, Dyno2 was run today in Nov. Dyno run 1 is with Werkes Exhaust + Penner Tune + Stock Headers Dyno run 2 is with Open Exhaust + Penner Tune + 2.5inch...

Paul is sponsoring the Bonneville run so I don't want to say a price as I don't know if that is what everyone will pay or not. They are not cheap. He had a week off so there was a small lag in the production of the pipe. There is still some back and forth while we get things right.

Here are some of the latest pictures, they are still in the fabrication state and not coated so not how they are going to look in the finished product. You are looking at the heat shields over the top of the header pipes.

I’m in the system for one whenever they become available. Looking forward to it!
