Kerker exhaust 81-82 250r?

[three_wheelin45]

Well I have been trying to find out what kind of pipe I have on my 82 250r, It looked like an answer until I saw the kerker exhausts I think that what it might be ;O but is there any specific way to tell?? Cause as far from what I can see theres no numbers on the silencer...

I don't know anything on your exhaust but , i have a new maier front fender 81-82 model and a rear set of fenders if your interested ? I am located in Dayton .

Maybe Fabio will chime in. He has a Kerker on his R.
Comparing it to a kerker, it seems to have some differences on the very end of the silencer.

It has no vin numbers on it or stamps...

Be sure to wear a helmet every time you ride that 250r. It will make your 200x look like a childs toy, and that thing can get out of control quick if you dont know what your doing. Just trying to look out for you, and nice to see another air fooler come back to life.

I'm no expert on the Air-Hammers, but it looks like you have a re-painted stock pipe with some sort of aftermarket silencer....

Ya, Honestly I wear my helmet everytime I ride since I wrecked my 200 ridin a wheelie down my road...

That is a stock expantion chamber with an old school dg silencer.

Ok, that would be the silencer.... The pipe is on the other end of the exhaust system..

And as to what brand your silencer is, it could very well be a DG... For as many years as they have been around, it's doubtful they are making the silencers the exact same way they did 25+ years ago....If there are no identifying markings on it, I would take the word of those here who recognize it. And FWIW, the silencer has no significant influence on performance anyway..

Well the silencer is what I obviously meant if the header is stock, I obviously knew the header was stock. Also yes just a slip on exhaust can make a differene, but ya the headers make the most difference like my 240 blaster was slow with the stock header, but with the Fmf header and silencer it was amazing the difference (way better take off and atleast a 10mph top end difference) Crazy how some metal can make a diff...

Well, the way you worded the post calling it the pipe makes us think you were referring to.. well... the pipe. That's what it is known as....

Also yes just a slip on exhaust can make a differene,
Sorry to say, but it doesn't. What determines your HP, power curve, and torque is the expansion chamber length, taper, diameter and stinger length and diameter. Silencer is just that... a silencer.

but ya the headers make the most difference like my 240 blaster was slow with the stock header, but with the Fmf header and silencer it was amazing the difference (way better take off and atleast a 10mph top end difference) Crazy how some metal can make a diff...
Exactly! The difference was made in the FMF header, AKA: pipe.. Not to mention, the stock exhaust system was most likely waaaaayyy out of it's league running on that 240 BB kit!

Not trying to be combative here... Just the facts.

okay well a silencer is knows as a slip on exhaust... tell me how this happens then?? http://hmfracing.com/shop/pipes/yamaha/raptor-350-05-09 (will pick up 8% horsepower) http://hmfracing.com/shop/pipes/pola...tlaw-500-06-07 (makes 7% more hp) but slip ons/silencers dont do anything remember... sorry bud but your wrong there...

Ok, you are comparing apples and oranges when you are comparing a 2-stroke exhaust and 4-stroke exhaust and how they work. In some cases on a 4-STROKE performance gains can be seen with a better flowing muffler. But optimum gains are achieved with the header and muffler combination along with upgraded intake, IE better air filter. I would also take the "dyno sheets" provided by HMF, for HMF add-ons with a grain of salt. Apparently, you don't realize the differences between 2-stroke and 4-stroke exhaust systems and how they work...

BUT, we were/are talking about your 2-stroke 250r here aren't we??

I have been wrenching on and riding these things since before you were born. I'm not wrong on the original point being discussed...

Done here.....
