Veefer800Canuck Posted January 15, 2016 Share Posted January 15, 2016 Those specs seem close enough and it's gonna be worlds better than OEM, or any of the aftermarket ones currently available. One look at the system from the 400cc V-four tells me that. Link to comment Share on other sites More sharing options...
Member Contributer MBrane Posted January 15, 2016 Member Contributer Share Posted January 15, 2016 Yeah the only power loss is below 2500 on the two brothers The only time my bike is below 2,500 is when it's idling... +1 slipping the clutch a bit more from a stop in town is not an issue for me.

Member Contributer Rush2112 Posted January 15, 2016 Author Member Contributer Share Posted January 15, 2016 Ok, we are moving forward with the 36.1 mm primaries. I emailed Tyga this evening: Hi Matt, I've gotten confirmation from enough folks to go ahead and move forward with 36.1mm ID primaries. They are slightly larger than the RC45 OEM primary diameter (35mm) and the same diameter as the Two Brothers Racing headers (36mm). So to recap what I understand you have the current tooling and capability to fabricate: Primary: 1 1/2” x 1 mm wall. ID - 36.1mm. Secondary: 42.7 mm x 1 mm wall. ID - 40.7mm. Final: 2” x 1mm. ID-48.8mm. Please let me know if I captured this correctly. I look forward to discussing our next steps in the project. Highest regards, Link to comment Share on other sites More sharing options...
Member Contributer Mohawk Posted January 15, 2016 Member Contributer Share Posted January 15, 2016 Just an FYI, there is NO significant low rpm loss with the TBR. I carry my other half on occassion & the bike will pull cleanly from 2600rpm two up in appropriate gear. FYI I don't ever want or need to use 6th gear at 20mph, that's why we have a gearbox ! have a look in my galery at the latest dyno from 2015 showing the fitting of the TBR & my Yoshi style stacks, apart from fueling those are the only mods , so its perfectly good all through the rev range & much better up top. I'd love to try a set of those Ladybird Ti headers, just to compare with the current setup, if anyone wants to donate them for testing, I'll pay for the dyno time :) Link to comment Share on other sites More sharing options...

You had good success and service, correct? ... Assuming the proper dyno tune - the mid range is fatter and of course the boost on the top? Yes? Effective fuel injection management are a must to get full benefit out of any performance exhaust mods... they are not just plug n play and these Tyga's are no different. Are you still in and committed to purchase with the new larger 36.1 mm primary dimensions? Link to comment Share on other sites More sharing options...
Member Contributer HighSideNZ Posted January 16, 2016 Member Contributer Share Posted January 16, 2016 Just my 2 cents worth on the pipe sizes. The Shark RC45 system I modded to fit my bike has 1 1/2" primaries, 1 3/4" secondaries and a tail pipe of 2" the same as the proposed Tyga system. I do not believe there is any real loss of low end power and a butt load to gain in top end. In my situation I feel that a good chunk of the power I gained is directly associated with the pipes. I think these will be good for the 5th/6th Gen members but if they follow the standard front header pipe layout, they will not suit the 8th Gen due to the low radiator fan with the front mounted rads compared to the side rads.

Cheers Phil I agree 100%... well, I have a slightly different perspective on your power gains, some of that may be due to the extra cc's We are moving forward with the 5/6 gens and if support is strong enough we will engage Tyga to create the front pipes with a couple of bends to accommodate the 8th gen radiator fan... the rear primaries should work on all three gens. Can someone with an 8th gen measure the width of the pipe clearance in the front necessary for the fan recess and measure the distance where this recess is centered above the lower bend where the pipes turn under the engine?

Member Contributer boOZZIE Posted January 18, 2016 Member Contributer Share Posted January 18, 2016 I believe we have agreed apon that we are using the 5/6gen architecture, that is that the diagonally apposed exhaust primaries are mated together. Please correct me if not. Will/does this have an effect on ?:- - 5.5gen (left bank mated/right bank mated) - 8gen (fronts mated/rears mated) Cheers Link to comment Share on other sites More sharing options...
Member Contributer HighSideNZ Posted January 18, 2016 Member Contributer Share Posted January 18, 2016 I honestly do not believe that the mating will have any real effect on performance. The RC45 pipes I'm running are mated both fronts and both rears. This is in the 180 deg crank gen 5 motor and I'm getting really good power out of it. My feelings are that the original 5/6th Gen were a compromise to make fitting the lengths better. With mine I have longer primaries on the front with a shorter secondary, and shorter primaries with a longer secondary on the rear. This seems to make a difference to AFR front to back, with a good spread of power across the board. Phil Link to comment Share on other sites More sharing options...

The 8th gen exhaust is not optimized for performance. If we had 360* crank shafts the pairing of front together & rear together would make more sense.
