    Has anyone cut off those two protection bars off of the header of the oem exhaust? I need to do that to install the CF protector I purchased. I know stainless is tough so I may take it to an auto exhaust specialist?

    Did my first ride this morning with the new wing exhaust. At idle it's not that bad but the twist of the throttle makes it louder. For dudes that like to keep things quiet this is not nearly as quiet as the stock. Going to try the quiet insert when I get home.

    Are you referring to the front piece from Carbon Performance? I contemplated cutting off those small bars from the header, then after lots of fucking around, I managed to get it on there. Bent one of the tabs down, put the clamp through the bars and bent it back enough to get the bolt on there. I'll pull the CF piece off later and snap a photo of the clamps, but here's what it looks like now. Been on there for about 2 months now.

    Question...i bought a 2008 that had a stock exhaust and airbox. it was zapped with the Akro map (as previous owner had an akro can on it before he sold me the bike). Ran well...i added a fmf apex can (loud as heck and loving it). bike is now very "surgy". I'd like to keep the stock airbox (lots of deep water crossings where I ride).

    Anyone have this set up and gave a good mapping?

    Thanks in advance

    Has anyone tried to mod the stock can by taking the catalyst out? I know it would require some significant cutting to get it apart, and subsequent rewelding, but I've seen it done on other bikes to reduce heat output and weight. I actually like the stock can because it's quiet, not so fond of the heat.

    When I had that apex on mine, I didn't notice it to be surgey...unless I just got use to it. I do tend to ride this bike a gear higher than I would other bikes though.

    Did you "reset" the the throttle after mounting the apex? Do you have access to Tune Ecu and cable?

    If you "clean" it out it won't be quiet anymore.

    Buried deep somewhere on this forum there is a thread with photos and a write-up of someone who cut open the end of the OEM muffler, removed the baffling system, and ripped the catalytic converter out. He then reassembled and welded it back together and it looked pretty good. As I recall, sound was a bit louder but deeper, and the exhaust was noticeably cooler. Still, a lot of work, though. And at the end of the day, the OEM muffler is still heavy, made of steel.

    I tried searching for it, but no luck.

    Why yes!

    You sir, are a legend. Thank you. Will try to replicate what you did.

    No sweat. Figured it might save you the headache I already went through.

    Also note I put a small dab of JB Weld around the two screw hole posts on the mounting clamps. I found that one of them wasn't as snug as I would have liked. I let it harden overnight before firing uup the engine to heat them up. That was a thousand Kms ago. All good, now.

    Good idea to use blue locktite on the screws.

    Tried the quiet insert. I think that's the ticket for me. Still has good sound.

    Yeah, don't use it.

    I sell the stuff for a living and I'm encouraging you not to use it-especially a red acetoxy cure RTV.

    You're gonna like that Wings can.
