Keep Baffle or Not?

[Springbok_Rider]

Hi,

I just received and fitted an SP Engineering stubby exhaust to my SV650 today and it sounds awesome.

I've got the baffle in at the moment, although wondered if there was any negative effect of having it out? Maybe for touring it would be a bit deafening or drown out headphones. But are there any negative effects to be had for the engine such as valve damage?

Regards,
Antony.

Deffo leaning that way, although what about all this talk about a drop in performance due to back pressure etc?

Which option is the air:fuel mix set up to suit?

Personally, I prefer riding bikes with baffles in/road-legal exhausts, I can better hear what's going on around me and it's less likely to upset non-bikers too.

Don't quote me on this but I thought generally removing the baffle improved the performance but only very slightly, due to the pressure in the pipes not having to be as high as it would be to push the exhaust gases through the baffle. Don't think it makes much difference whether the baffle is in or not really apart from noise.

[Springbok_Rider]

I'm not too certain what the air/fuel mixture is at the moment, nor how to really tell if it's lean or rich. I've only had the bike 3 weeks and it's my first.

Edit: Well, 2 weeks although I did ride it from the UK to Norway. I guess as long as having the baffle out isn't detrimental I can see how I go.

My exhaust sounded pretty shit with the baffles in, took them out and and POW! If you're happy with them in though...

[Benson_JV]

My exhaust is very short and has zero anything inside the pipe, bike hasn't blown up, all that happens is it runs slightly lumpy at idle. You'll be fine, take it out.

I must be getting old Really don't see the point of a noisey exhaust. Love the quite smooth sound of my Busa as it pulls away

Take the baffle out, put it somewhere safe and pop it back in on the morning of the bikes MOT.

Some sort of reverse psychology here to make me want to keep the baffle. Technical opinions people, I don't need to hear about insecurities!

I also agree with all the prev posts, but on a motorway it's does your fucking head in, maybe if your your doing long journeys, replace baffle, but for pottering around, take it out.

since the stock surface-to-air missile launcher came off my bike and i had it fitted with an after-market can, i still don't know what it sounds like with the baffle in. even went for it's first MOT without the baffle. i think they gave me extra credit for it.

Fair enough. I do like the sound of it with the baffle, although without is another story. I do get what people are saying in regards to the neighbors, although around town surely there isn't a person alive who thinks the sound of a singing V twin is a bad thing?

Wouldn't want to try find a dyno place here in Norway, they probably have one hidden somewhere in the woods that'll cost a month's salary to use. Guess if there aren't any dangers to the engine, I can try to use good old fashioned sense.

I had my baffle out for 2 years, put it back in for the MOT and it runs far far better, less engine braking(less harsh), much more midrange(a noticable amount) and is smoother in general.

The sound is slightly different, less boomy, but the midrange has transformed the bike coming out of corners.

Try both!

Do you want to ride your bike or attract attention?

Loud pipes may or may not be desirable, my opinion is yes they're fine on a race track, but not crazy about them on the road. I like them even less when they're keeping me awake at night (cars and bikes).

You are without doubt more likely to get pulled over for having a loud pipe. Every time you get pulled the chances are they'll find something else if they want to. Is it really worth the hassle?

Riding off road as I do, I am well aware that the biggest single issue that pisses of the public with regard to bikes is noise.
