i'm sure ice would wanna check this out. if you play part 1 and 2 at the same time while revving you really get to hear the difference between stock/slip ons.

the y-pipe and juicebox make it feel/sound even more different once you're riding it.

thats the setup i want...just having a hard time with the $1200+ for exhaust....i will pull the trigger one of these days...lol

[Brendel]

haha. slip ons by themselves are like 800 bucks, can probably find em for cheaper somewhere, maybe ebay. slip ons alone make the biggest difference anyway

Any poppin noise now with the juice box ?

[Brendel]

yeah, it's still there sometimes. that popping you hear according to some forums might be intentional. some parts might let air in so that it can combust any unburnt fuel before it leaves the exhaust. since multiple bikes do it, and even yours coming straight out of the dealer do it, i'm assuming it's normal.

[ice]

if you are in MODE A the bike dumps more fuel into the intake. Mode A is meant for the track or open freeway....around the city streets just use the normal mode..

the popping is a backfire from unused fuel hitting the hot header exhaust pipes and catching fire.....wont hurt the bike but over time it will make your exhaust louder bcuz it burns the baffle packing in the exhaust

hey iceman wasn't wasn't able to pay attention to wat u wrote the boobs  kept distracting me jk.

[Brendel]

i dont even have baffle packing in my exhaust haha

[ice]

All pipes have a baffle and packing...its a CARB law.

if you took the packing out of your pipes it could explain the low numbers on the Dyno. your exhaust provides a certain amount of back pressure that the engine needs in order to produce power. unless your running a full exhaust and do nothing but drag race and have a ton of HP the i suggest putting the baffle and packing back in.
