    My website is terribly out of date and only lists my 70's Classic range of pipes. Any interest can be made directly to me at paul@vikingexhaust.com

    They certainly are Kevin.

    I will be suppling Carbon fiber heat shields with this 2.5 pipe. There is a "posibility" that heat shields may be made to suit the 2.3 pipe.

    Yep, a common story.

    About a month by the time I build the system, have it coated, then ship it. As I sell Globally, the "riding season" is all year 'round. E.G. our riding season here in NZ starts at about that time, tho' I for one ride all year round.

    Exhaust pipes are hot, a lot of people don't seam to understand that concept. Nothing will "reduce" the heat coming off a fire. When people talk about "Hotting" an Engine up, that is eactly what happens, you increase the air/fuel you are going to increase the fire,. The more fire you have...

    I'm about two months out on production, pricing will be announced at that time. The header and the muffler are two seperate piece's, if you wanted just the header that would be no problem but keep in mind that all the after market "slip on" systems are made to suit the very small (1¾" O.D.) tail...

    I have been selling Globally for over 30 years. The fact that this pipe is not suitable for you concerns me not. I can't please every one, and I don't try. The "noise" is not at all "un-bearable" All of my Exhaust Systems are built for road going Bikes, not race bikes. So the power and torque...

    I'm not sure what programs Brett uses to access the ECU. No I don't supply tune, as mentioned in another thread, a tune I would supply is for NZ conditions, fuel etc. This has caused grief in other parts of the world with the different fuels etc. A canned tune is never 100% correct for your...

    US$500-1000 seams excessive ! The dyno tune done here by BRM was around NZ$500, that's US$306 When you say a tune only, that would be a "canned" tune, so not nessarily 100% correct for your individual bike, fuel, ambiant conditions, right ? In the past people would ask me for a tune to go with...

    Using the figure of 25% loss that makes the real world RWHP of 182.5, 250 HP at the crank. Do ya think ? A 20% loss would mean that RWHP of 182.5 would be 230 HP at the crank. Choose your own numbers. What ever the crank HP is, the RWHP as done at BRM Tuning in Paeroa, NZ was 182.5

    General concensus is there,s between 10-15% power loss through the drive train, depending who you talk to. So by taking the real world rear wheel HP and calculating back by that % figure you get the crank figure.

    182.5 RWHP. The bike MUST BE Dyno tuned to suit.

    There's a lot of "interesting" opinions stated here. We built a header for the 2.5, had it tuned properly, 215 crank HP. That's a 35% increase over stock. No other mods. So for those who say "just a header won't make much difference" you're way off base.

    The stock header has a one piece manifold plate, as does my system. I can't see why this would cause leaks. If anything it would be more stable.
