OK, this is something different ;-)

More from "Nice sounds, look ???" - hope it does not become boring ;-)
http://v.youku.com/v_show/id_XMzczMTE0OTg4.html - it shows clearly, that the cat-conv IS removed...;(
http://v.youku.com/v_show/id_XMzg5MjgwMTY0.html - terrible video quality, but at least "the look" (of the silencer) is not bad (imho)
Wow, I doubt that pipe is going to clear the rear wheel.
Probably not.
The original design is thinner on purpose.
Tomtom, why is removing the cat a bad idea? I've seen several rebel raptors with this mod and a Suzuki gz150. I thought less restriction in the exhaust flow was a good thing.
Nuhaus, I hope Tomtom will respond with his thoughts. I've tried these mods on smaller bikes and really they make little difference except for the sound. A motorcycle engine is in many ways like an air pump there's not much point in having a fast exit for exhaust gases if the way in is as slow as ever, I've tried just putting on a straight-thru muffler, but I think it was a mistake. I've tried removing the air-box and putting on a clip-on fliter which helps the bike suck air in but really if the EFI or carb do not allow a better fuel mix you'll just end up making the bike more lean, sometimes if you have a cheapo Chinese carb bike you can fairly easily raise the needle height or put in a bigger jet and then get a tad more horses maybe half a one, but I don't know if I'd bother trying to second guess Italian or Japanese EFI tech design without a dyno. Obviously with some racing bikes they have open-mouthed after market mufflers, however these are generally tailored to each bike specifically and have been tested usually giving extra power at the sacrifice of some torque. IMHO, and I'm no expert but those baffles, spacers and the cat is in the muffler because it is a street bike to give you back-pressure to keep the torque which makes the bike more usable for a real world non-racing situation and obviously more environmentally friendly too. I for one wouldn't want an inline 600 on the road that was sluggish in the mid range torque band but was marginally more powerful around the red-line.
Thank you for the thoughtful response. I have looked on a few boards at different ideas concerning exhaust systems on bikes and there seems to be a wide range of opinion on removing the catalytic converter. In my own experience with scooters, I've noticed that making the intake and exhaust ports more open produced a noticeable increase in power. On my Suzuki qs150a, I modded the airbox and muffler in a similar manner and again, more power. However, when I tried the same trick on a Honda Rebel it was a disaster. My CB400 on the other hand had a modded exhaust and runs remarkably well. Xiao Cui and 998S were both impressed with it when they rode it, and its new owner so far has no complaints. :)
With a bike like the Benelli, however, the addition of EFI would seem to make things more difficult. I'd really like to see some dyno results from the mods people are doing with them. For now though it looks more like the "snakeskin seat" style of mod.
I thought so too. Looks more like snakeskin than leopard skin.Quote:

Nuhaus I'd like to think that anyone riding an inline 600cc bike in China wouldn't really need a tad more power at least on the road, which really means it's all been done for show, plus you illegalize the annual compulsory testing after the bike is 2 years old. Leopard-skin, snake-skin, whatever it's all freaking poor taste. Sometimes motorcycle customization seems to me more like desecration. :rolleyes1:
