FigJam-OhNine Posted February 3, 2015 Share Posted February 3, 2015 Strongly considering trying out this mod, thoughts on the sound from this vid? I don't get it. Did he just gut out the catcon? Why not just remove it completely and put in a straight pipe? Seems like far less effort. Link to comment Share on other sites More sharing options...
papac2000 Posted February 3, 2015 Author Share Posted February 3, 2015 The stock exhaust has 3 chambers and a very circuitous route for gasses to flow. This guy removed the cat, put in a perforated tube/piece of metal from inlet to outlet and packed the whole thing. It also has a larger outlet. Lots of work maybe, but looking for a mod to get a bit more sound....and one that won't visually tip off my wife I have spent money on the bike. Also less conspicuous, and some insurance companies will not insure "modified" motorcycles. 2015 Matte Grey Modded stock exhaust, modded stock screen, modded stock seat, OEM heated grips, LED indicators, FlashTuned ECU, ZX10R shock Link to comment Share on other sites More sharing options...

papac2000 Posted February 3, 2015 Author Share Posted February 3, 2015 Depends on your dealer I suppose....if you remove the exhaust entirely and put on aftermarket (other than Akra from Yammy) its kind of the same thing. But I know people who have gotten warranty with slip-ons and power commanders on other bikes. 2015 Matte Grey Modded stock exhaust, modded stock screen, modded stock seat, OEM heated grips, LED indicators, FlashTuned ECU, ZX10R shock Link to comment Share on other sites More sharing options...
fjrider Posted February 13, 2015 Share Posted February 13, 2015 If it is like other Yamaha cans, it has chambers and tubes that criss-cross the exhaust before leaving the tip. Just do it on the top where it will be harder to see. Link to comment Share on other sites More sharing options...
Premium Member ULEWZ Posted February 15, 2015 Premium Member Share Posted February 15, 2015 I have been researching aftermarket exhaust, and there will be clearance issues with the center stand with most exhausts. So what about modifying the stock exhaust? Found on an FZ-09 site where a guy removed the exhaust cover (3 screws) and cut off the exhaust tip to the second weld and welded on a slightly wider tip. The wider tip required him to oval out the end to fit. The stock exhaust tip is in two layers (1 pipe in another larger pipe). He then cut the inner pipe back as far as possible inside the exhaust chamber, thus exposing the inner chamber. He claims increased deep tone and slightly louder. I may try this in the future. If anybody else tries this, please post up pictures. A government which robs Peter to pay Paul can always depend on the support of Paul.

papac2000 Posted February 15, 2015 Author Share Posted February 15, 2015 I had read the info on this as well. I don't mind the look of the stock system, I think it suits the bike. So far none of the aftermarket systems keep the underbelly layout which I prefer. I'm debating how far I'll go with modifying the stock can, but it's on my list of mods for sure. 2015 Matte Grey Modded stock exhaust, modded stock screen, modded stock seat, OEM heated grips, LED indicators, FlashTuned ECU, ZX10R shock Link to comment Share on other sites More sharing options...

I kind of regret upgrading exhaust on my FZ-09. It's so damn loud. Sounded cool at first but damn, I can't even barely hear my headphones now. I kept the stock and might even put it back on.

Premium Member ULEWZ Posted February 16, 2015 Premium Member Share Posted February 16, 2015 My problem with the exhaust is when I am really wicking it up in the canyons. I concentrate on the road and rely on the noise the engine is making to tell me when to shift, etc. If an exhaust is too quiet, then I must look down at the tach, sometimes at inopportune times. The tach is a useful tool that I in fact do use, so don't get the wrong idea, I just prefer listing to my engine and let it tell me what to do. I also wear earplugs due to the wind noise, so a loud exhaust is fine for me (just not too loud that it pisses off the neighbors!).

I'm about to pull the trigger on the Akrapovic Ti pipe just because I can choose to run with the baffle in and I hear it's really tame. Only marginally louder then stock.

papac2000 Posted February 21, 2015 Author Share Posted February 21, 2015 Well...I took a crack at the stock muffler today. I would consider this maybe Phase 1 since there were various ways I had thought about doing this. Its completely stealth since I accessed the rear chamber (where I planned to make the mod) from the top, and once reinstalled you would never know its been touched. I was afraid to go too far on the first try, but would/may try to get a bit more sound yet in the future. As it stands, it made a noticeable difference. I took pics and will put in a new thread with the YouTube vid of a quick dyno pull. 2015 Matte Grey Modded stock exhaust, modded stock screen, modded stock seat, OEM heated grips, LED indicators, FlashTuned ECU, ZX10R shock Link to comment Share on other sites More sharing options...

I think I will do this mod. I have a friend with a welder (good welder too) that owes me one. A government which robs Peter to pay Paul can always depend on the support of Paul.
