Good exhaust, But you will have to have the ECU flashed!!! Bike already comes lean to pass epa BS!!!Adding the exhaust will only make it run leaner..
Good exhaust, But you will have to have the ECU flashed!!! Bike already comes lean to pass epa BS!!!Adding the exhaust will only make it run leaner..Hello!
What are your thoughts on the M4 GP Exhaust? Read online that even though it's a slip-on, it deletes that stock catalytic and comes with an O2 oxygen sensor bung. Will that get my ECU to start acting funny or idle weird? I'd hate to have to tamper with my ECU.
Thanks,
Sam
Even if I kept the stock cat on? I'd hate to experiment with tunes on a brand new bikeGood exhaust, But you will have to have the ECU flashed!!! Bike already comes lean to pass epa BS!!!Adding the exhaust will only make it run leaner..
If you leave the cat on and just do a slip on you could get away with it, remove the cat and you SHOULD get the ECU flashed...Like I stated they come lean from the factory..Even if I kept the stock cat on? I'd hate to experiment with tunes on a brand new bike
Do you have a dyno chart or an AFR log to go with that claim?Without a full dyno-tune, any slip on or full exhaust you get will decrease your HP and increase the cool factor of crackles and pops and flames due to the lean fuel/air mix.
LOL, you prove me wrong. If slip on increased HP without tune, they would not crackle and pop because their fuel/air ratio would be correct - hence a possible increase in HP.Do you have a dyno chart or an AFR log to go with that claim?
The crackle and popping happen when you release throttle, which is a point where you're not even asking for power. Even with the stock exhaust you hear very minor crackle/popping, an aftermarket exhaust only amplifies that.LOL, you prove me wrong.

It is not common sense, it actually doesn't even make sense. I never claimed the M4 made hp nor am I after hp with the M4 exhaust, it's purely for the GP sound and to get rid of the ugly looking OEM exhaust. I'd even sacrifice a few hp's for that I don't mind.It's not a claim, it is common sense. Even I as a non-mechanic knows this. So you prove to me that a m4 exhaust slip on without a dyno tune will increase HP.
Ahh ok, so you essentially concede that slip on without a full dyno tune will cost you HP, and add some crackle and pops, and sacrifice overall engine longevity is acceptable.The crackle and popping happen when you release throttle, which is a point where you're not even asking for power. Even with the stock exhaust you hear very minor crackle/popping, an aftermarket exhaust only amplifies that.

The extra air flow you get from an exhaust causes your engine to run lean, meaning there's not enough fuel being burnt actually, so how does that translate to popping and backfiring? If there's not enough fuel being burnt in the chamber you think there'd be enough left to burn in your exhaust and cause popping and backfiring? :dontknow:
