Exhaust baffle

[Fulhamatt]

While cleaning my bike earlier, decided to remove the baffle from my can. Had a play about and made the bike sound smoother if anything, not much louder though.

Anyone know what damage this can do to the engine, have read stories about a lack of back pressure damaging the engine? thinking of removing mine for a while to see how it goes.

removing the baffle will make the engine run slightly weaker on the fuel mixture but shouldnt do any lasting damage

Thanks mate, forgot to ask this aswell. One of myneighbours works at the Suzuki UK head office and warned me that removing the baffle (Aftermarket can BTW) will make it flatter in terms of performance, is that right?

[eastanglianbiker]

it can do due to running weaaker but very often you will hardly notice

Depends on the pipe and bike.

Most aftermarket pipes do not need any adjustment after the baffle is removed and they wont run to lean.

However you will always get a better result if you do get the bike dyno'd and the fueling adjusted.

The bike should run fine without the baffle in in fact you may even notice a little improvement in the midrange (although probably not as it would be very small).

I run my tiger with a blueflame exhaust without the baffle and no aftermarket tune. It runs fine, picks up a little better and is not running lean (checked on a dyno power run).
