wooosaaaw Posted July 6, 2015 Share Posted July 6, 2015 Hey Everyone, So i found this video: and decided to give it a try today. I used a 3/4" square wooden rod about 24" long and a rubber mallet. I used WD40 to lube the seal and saw it seep through to the other side. I found that the wooden rod mostly sat in the crease between the baffle and the exhaust and after about an hour of trying to hammer it out i just about gave up. I noticed that you can try to get the wooden rod above or below the baffle tube but i had no success either way. I was only able to get it to move about 1mm. Any suggestions are greatly appreciated, I'm not sure what i'm doing wrong here. Link to comment Share on other sites More sharing options...
Allan Posted July 6, 2015 Share Posted July 6, 2015 I got mine out using this method. I didn't use a piece of wood though. I used a really weird metal tube thing with a flat head. It looked like a giant nail. If I remember, I'll post a picture of what I used. I just had my friend hold it while I shoved the "nail" into the end of the exhaust and pounded it with a rubber mallet. It came out in about 15 seconds of pounding using this method. Link to comment Share on other sites More sharing options...

I ran the bike up to full temp got exhaust nice and hot and used co2 to freeze the db killer, got a pair of vice grips and a hammer and it slid out. It's definitely a interference fit. Heat expands the exhaust side while cold shrinks the db killer. I did some baffle modification to see if I could get a good in-between sound. (Quick answer is no not without machining and new one.) I froze the baffle overnight and got the bike warm. It slid right together after doing this. I could even twist it for about 15 seconds until the baffle expanded to "fit" the exhaust.

wooosaaaw Posted July 13, 2015 Author Share Posted July 13, 2015 I finally got it! A pair of Channel Lock Pliers and a hammer is what it took. I had to clamp onto the baffle and hammer the pliers outward. It mangled the tip of the baffle but i plan on cutting them down as well as cutting the inside so i can put it back in. HOLY SHIT ITS LOUD! Link to comment Share on other sites More sharing options...
Premium Member wickedtwister Posted July 13, 2015 Premium Member Share Posted July 13, 2015 I intended to do the same thing but we'll its hard to go back to the baffle after hearing the glorious thunder that is the exhaust without the baffle.

wooosaaaw Posted July 16, 2015 Author Share Posted July 16, 2015 I intended to do the same thing but we'll its hard to go back to the baffle after hearing the glorious thunder that is the exhaust without the baffle. I ended up cutting off the internal pipes complete off and shortened the external ones (only because i mangled them) and it is still pretty loud but not ear damaging loud. A good balance. On a side note, i noticed Akrapovic is making a new sound insert pictured [/url]here For the CBR650 you can buy a 4 baffle design similar to ours or the one from the link above which is a single large baffle. I imagine the single large baffle is much louder. Hopefully they will sell this to fit the fz-07 Link to comment Share on other sites More sharing options...
