No baffle good or bad on 400ex stock exhaust?
Hi,
awhile back i baught a honda 400ex, but the exhaust's baffle was cut out . It still has the chrome covering on the back of the muffler. Is it bad on the engine? If so how bad. I am not shure if the not having any back pressure is good on it? and how it sucks cold air easily back into the engine. thanks!

I ran with no spark arrester for 6 months on mine and the only problem i had was my neighbors [img]i/expressions/face-icon-small-tongue.gif[/img] my friend did that too and we never had problems with our rides. theres a lot of restriction left, take a flashlight and check into your muffler youll see [img]i/expressions/face-icon-small-tongue.gif[/img] dont try to put another spark arrester in it cuz youll lose this nice sound and a little bit of power [img]i/expressions/face-icon-small-tongue.gif[/img]
dyno test : stock 400ex with the spark arrester vs stock 400ex without the spark arrester

Some already think about something without cutting any part, but you'll need to pay for it

a bit expensive but great look
