Beemer Posted March 10, 2016 Share Posted March 10, 2016 Akrapovic Carbon Fiber she needs a bath beemer otherwise not a bad look with the belly-pan how hard was the install because of that? Another week or so and I'll clean it. I'll pay you $1.00 over minimum wage to clean it now if you like. Thanks, it does look good. I installed the belly pan long after the pipe so no problem.

ducttapewd40 Posted March 10, 2016 Share Posted March 10, 2016 Got my M4 in the mail today. Gave it a test fit and started it up, then took it back off and just got done painting the pipe and headers black. I never liked the color of the stock system and having a different color pipe than headers bothered me even more. I'll get it installed tomorrow once it's dried overnight and take some pics.

gregjet Posted March 12, 2016 Share Posted March 12, 2016 Sorkyah :"Neg wave generator?" A short while ago someone posted a link to a MotoGP and Formula 1 exhaust technology using a "new" method of generating the negative ( extraction) wave by using a step up in diamater near the head. I am still trying to find a serious engineering description of the practice but suspect it lies in original 2 stroke expansion chamber design ( or parallel concept). It could help with the problem of std sonics being out of phase because of the crank/firing config. The formula 1 design is a simple step. The one on the Yammy MotoGP bike is a little smoother. I am beginning to wonder if the bulge at the end of the Akro is there to do that. It is about ( roughly) twice the distance from the valves that the MOtogp one is , which would make it about the right place. Go forth and modify my son...go forth and modify...

Makes sense i could definitely see a tuned expansion chamber design helping the flow, im not sure how well though since it might not work 100% of the time with a 4-stroke motor, unlsss of course the engine is built with that design in mind ATGATT...

gregjet Posted March 13, 2016 Share Posted March 13, 2016 The reference was to the diffuser cone on a two stroke expansion chamber which is closer to the head than the baffle cone. Four strokes are commonly the other way around effectively because it's easier and there is an entire stroke before the neg wave comes back and does its work. It looks like the closer "reflector" does it on the same stroke but , again, I haven't seen the physics they are useing explained. ie I am guessing! I really want to get this one explained as it will be revolutionary if it will work at the lower rpm of street and dirt engines. Go forth and modify my son...go forth and modify...

Tristar Posted April 1, 2016 Share Posted April 1, 2016 Just got my SC Project exhaust installed today! EJK isn't showing up in the mail till tomorrow so I haven't gone out and ridden it yet but even just running it down the driveway and back it sounds amazing. I left the baffles in for now but once I've got the tuner going I'll take it out for a ride with baffles in and out to compare. Link to comment Share on other sites More sharing options...

sansnombre Posted June 19, 2016 Share Posted June 19, 2016 I added this because it shows the whole Akro Snail pipe exhaust. It's an old pic but the best one for showing the total exhaust. Hey, how do you like your shock? Link to comment Share on other sites More sharing options...

gregjet Posted June 19, 2016 Share Posted June 19, 2016 sansnonbre, Only got the Nitron because Ohlins were not available when I bought it. I feel it is a touch harsh but streets better than then the stock junk. It behaves itself pretty well but needs some compression fine tuning. I am concentrating on my GS500 project for a while so it will have to wait. Go forth and modify my son...go forth and modify... Link to comment Share on other sites More sharing options...
