Slono Posted November 24, 2019 Share Posted November 24, 2019 Thanks to @topazsparrow for guidance on installing the baffle. Its music to my ears and they don’t have to bleed anymore to enjoy the low growl and deep bass from the exhaust now. Not to hijack the thread but I gotta ask a quick question regarding the exhaust itself. How far in do the headers push into the engine? I feel like there’s air coming from that general area but I can’t pinpoint if it’s coming from the header joint. Link to comment Share on other sites More sharing options...

I cannot help with your question, but if you get one of those long candle lighters you can move the flame around the area to see if there is any air coming out that would cause the flame to “dance”.

RobZilla Posted January 28, 2020 Share Posted January 28, 2020 On 3/18/2018 at 7:05 PM, topazsparrow said: I just wanted to elaborate on why I think it sounds better than simply cutting or drilling the 07 insert. If you study the following images, you notice a difference between the 09 and the 07 insert beyond the addition of an outlet pipe. Notice the second collar / flange on the 09 tip? This is quite a tight fit inside the exhaust outlet (as a whole), As such it greatly reduces the air volume in that area (the area between the collar with the retaining screw and the outlet of the inner exhaust). The reduction of this space stops the resonant air compression you get with the cut 07 tip. It exposes the restricted outlet pipes to the deeper rumble of the 2nd chamber muffler exhaust but also redirects the excess back into the third chamber before it exits the "normal" exhaust outlets (the little tubes that mate with the DB killer). If you take your noise baffle / insert out and look inside with a flashlight you'll clearly see what I mean. There's actually two routes for the exhaust, leaving the stock baffle in ensures the most "complete" route for the exhaust gasses as it is forced through the third chamber. Removing the baffle stops the redirection of gasses back into the exhaust so it can mostly escape through those side openings on the 2nd stage of muffling. adding the Fz-09 baffle retains more of the pressure, and forces a decent amount of gasses back into the 3rd stage. It avoids that resonant air pressure issue (mostly) and effectively lets you run the third stage half open for additional thumpy goodness. The fact that the inner pipes don't perfectly align with the outlet pipes on the baffle also seem to help reduce that reverb / resonance flappy / farty sound I had with the cut pipe. Did you cut the flange off? Link to comment Share on other sites More sharing options...

RobZilla Posted February 5, 2020 Share Posted February 5, 2020 (edited) You just cut the tips off back to the flange and it fits fine. worked for me. The fact that the holes don’t line up helps from what I’ve been reading. The screw hole lines up fine. I was wondering if anyone cut more off, past the flange, on the fz09 insert to see how it sounds. Edited February 5, 2020 by RobZilla Link to comment Share on other sites More sharing options...

I didn’t cut anything because I didn’t have time so the 3 pipes at the end of the DB killer protrude from the end of my exhaust. It doesn’t look as clean but it definitely gives it a grungy hooligan look to the bike! Whatever you do, don’t cut the flange. It helps to retain the throaty sound.

mayt948 Posted April 9, 2020 Share Posted April 9, 2020 Just pulled out the baffle of my akra ti had to drill out the weld what a pain pulling it out. I'm about to buy the mt09 baffle for it. Does anyone know if I'm suppose to cut all three ends off of the mt09 baffle before the flange or do i just cut the one extra one off so that the other two plug back into the stock exhaust holes?

Just looking for some reassurance that I'm making the right decision I think so. I wanted to keep my original baffle stock incase I want to go super quiet again, plus many people say it sounds kind of "flappy" or "farty" with holes drilled, the cut 09 baffle I can confirm sounds great. 1 Link to comment Share on other sites More sharing options...
