Baffle in or out?
 

My girlfriend suprised me the other day by getting me a Arrow exhaust can for the GSR and yesterday I managed to remove the baffle so it now sounds very loud :)

BTW - the baffle in the Arrow can is around 6" long compared wit the beowulf one I had for the bandit which was tiny.

Are there any negative effects for an engine running an exhaust without a baffle in?

I have heard that it will reduce the amount of backpressure which could have an effect on low down power howver the GSR has an exhaust valve which increases backpressure at low RPM.....

I took the baffle out of my Scorpion. No change in anything other than noise. I'm keeping it out for the summer and I'll put it back in in the winter, so as not to annoy the neighbours too much. I don't think it makes any other difference, I've not even noticed any fuel economy or power change.

My replys the same as SV Mad. No probs at all & mine stays out all yr round, the neighbours r used 2 it...lol

Why would they get annoyed in Winter if they don't get annoyed in Summer??

I bought my SV thou couple weeks ago with Harpoon exhausts, no baffles, passed MOT, sounds loud, no effect to engine or power delivery. pop crackles and burbles nicely at certain speeds in certain gears off throttle which is lovely though :)

Y'put your baffle in, your baffle out, in out in out shake it all about!

Nah - you won't find any change. Some people claim that taking a baffle out will strengthen the midrange but I'd struggle to feel any difference. Enjoy your bleeding ears, that's all I'll say! ;)

I didnt get no baffles with mine \\:D/

They do get annoyed in the summer a little, but I leave for work between 6 and 7 everyday and as it gets darker the noise travels (and sounds louder) in the dark mornings so I put the baffle in to deafen it a little. It hardly makes a difference but I feel a little easier...
