Hello everyone Can someone tell me if it is possible to run my bike without the muffler, as with having the exup vaule in the exhaust would it provide enough back pressure for the engine without the muffler. Offer then the noise would it effect the preformance much if at all. Cheers CHRISO85
The EXUP doesn't control 'backpressure', it controls velocity. The variable restriction maintains velocity (just like the slide on a CV carb) to prevent reversion (think 'back-washing') and dilution / contamination of the fresh charge in the cylinder. It is this contamination of the charge that causes the power-loss when the EXUP is pinned open. Pedantic responses aside, the -muffler- is the source of backpressure, and you will be flowing a LOT more air, and will need to completely rejet. Plus your ears will bleed, your neighbours will hate you and set fire to your bike in the night, and the cops will have absolutely no problems finding you to give you a ticket. <!-- s:cop --><img src="{SMILIES_PATH}/icon_cop.gif" alt=":cop" title="Cop" /><!-- s:cop --> Don't do it.
yes it is possible ive done it and ridden up n down the street flat tack sounds so friken awsome and weirdly enough the bike clicked thru the gears easier. i meant like there was harldey any effort neeeded to change compared to normal. might just b me tho. just like an f1 car u can hear it from half a km+ away. only problem is ur performance aint tht great but is good for a laugh. just dont get caught.
Cheers for the info dontz125 I just like the idea of the underslung exhaust lol plus it looks mad, does anyone know of anyone who has made one with a muffler for there blke. cheers CHRISO85
this is what i have just stuck on. its a sweet can that sounds AMAZING. its really small so isnt very noticeable. i cant actually believe that its legal. lol. <!-- m --><a class="postlink" href="http://cgi.ebay.co.uk/Exhaust-Ixil-Dual-Hyperlow-Suzuki-SFV-650-Gladius-09_W0QQitemZ170331395348QQcmdZViewItemQQptZUK_Motorcycle_Parts?hash=item27a88ad514&_trksid=p3286.c0.m14&_trkparms=65%3A12|66%3A2|39%3A1|72%3A1683|240%3A1318|301%3A1|293%3A1|294%3A50">http://cgi.ebay.co.uk/Exhaust-Ixil-Dual ... 1|294%3A50</a><!-- m -->
Cheers mate did you have any problems with the install or was it pretty straight forward and do you know if the dealer that you bought it off would post one to australia. Thanks CHRISO85
"Post to: Worldwide" Says on the ebay link so that would be a yes. Sexy looking pipe as well. Deadbirds did you need a tune afterwards? If you did not is it running richer? Less power? Back pressure change at all?
Hey deadbirds can you post a video of it idle and revved. If it's possible can you also get one on the go would love to hear it on board and from the outside when you open the throttle.
im trying to get new headers. i just taped them up with loads of exhaust tape to see what the can sounded like. but i dont wanna run it much with broken headers. lol.
damn thats nice, what did you have to do to install? I noticed it was designed for a R6 so was there much welding, cutting?
