Baffles and pops and bangs

[PhillVR6]

I've just fitted my new exhaust and have removed the baffles, the bike rides fine, but pops and crackles quite a lot. Is this ok or do I need a power comander or something?

The bikes a 2005 Kawasaki Z750.

Thanks,

Phill

Enjoy the noise, that is what I say.

That looks the NUTS!

As far as i know with replacement can that just slip on there is no need to add a power commander. (I am looking at putting a new can on the CBR600RR)

I do remember that my old man put some straight through exhausts on his Suzuki Intruder 750 and that did pop and bang allot. I do not know allot about power commanders but maybe Hobo or Chilli might have the answer for you.

Does look good though nice choice

My ZX-9 had an early Blue Flame can and that popped and banged all over the place on the overrun.
That had carbs but even after a dynojet and full rolling road setup it still did it..

Some pipes on some bikes are just like that..

Power Commander may be worthwhile if you want to optimise fuelling and iron out any emmission related flat-spots but methinks the pops n bangs 'll still be there!

Nice one, just had a quick ride and it seems to go pretty much the same as it did with the standard pipe. If anything the throttle response seems a little less snatchy if you know what I mean.

I'll continue to carry the baffles with me for the foreseeable just in case I attract any unwanted attention though.

Thanks,

I too say popping and banging is a good thing,even the odd two foot flames(god i miss my Busa)

Less baffling means less backpressure in the exhaust. More mixture then squeezes past the closing exhaust valve. Hence lots of lovely popping and banging.

My Z1000 with Akrapovic cans sounds great, but no pops or bangs, but my mate's Speed Triple with aftermarket can (can't remember which) pops, farts and bangs all the time - lovely!

Thanks for all your replies, I'm now suitably reassured.

I'm actually very suprised it runs so well with what is effectively a race can, I was expecting flat spots, but there appear to be none.

It now seems to rev more freely throughout the range and I find it much more rideable in first gear where in the past it was a little on/off.

The only thing is, although I love the noise, I do worry about it drawing unwanted attention so have been taking the baffles and allen key out with me just in case.

You just de-clutch as you pass police cars.

Oh the number of crappy cars I had to do that with as I was growing up...

Or is the new exhaust leaking? if it is then you may burn out your exhaust valves! Not wanting to pee on you parade but I'd not be to keen on popping on the overrun.

My TL has a full M4 system on it and is Loud!! I went past some Motorcycle police (at a steady pace) and they just nodded in approval so i do believe how you are riding plays an important part.

Without a doubt, no, the stock exhaust started blowing some time ago so I'd know if that were happening, also there is only one place for it to leak (where it is clamped to the standard pipe under the bike and this is deffinataly tight.

Been out on it again today and I'm sure its a bit faster and the power delivery smoother than before.

By the way, already got in the habbit of knocking it up a gear or declutching when I see plod.

Thanks,

Fair enough, just thought it was worth a mention.
