Im going to be getting a new exhaust system for my YFZ and was wondering which one to get. I looked at dirtwheels and the FMF factory 4 and the Dubach racing ones came out on top. But they didnt test the Yoshi pipes. So has anyone experimented or had good results with any exhaust. thanks guys

 

I am partial to the DR D because of the
1) low price
2) good looks (subjective)
3) awesome power gains
4) Quiet insert so that you are legal in sound restricted areas
5) Ease of jetting for it (lots of info out there, recommendations from Dubach themselves using the stock needle)

You will get many other opinions on other pipes, but I feel the DR D is the best "all around" buy. [img]i/expressions/face-icon-small-wink.gif[/img]

PS, you can see a close up of it mounted on my pics page.

 

those pipes are all peak hp.the best pipe i have seen for the yfz450 is the new pulsecharger pipe .it makes the best all around hp not just peak hp .

 

it said the dubach had great low mid and revved out good on top but where can i get info on the pulscharger pipe. Im going to be riding on the dunes alot and trails so alot of faster paced stuff.

 

go to pulsecharger.net

 

I think the Pulsecharger is like $600.

Get it anyways, you'll be unique.

 

pulsecharger makes the 'widest' power out of all pipes. low to top power all the way across. They have recently redisigned them they had some flaws like bolts coming loose ect.. but they are now supposed to be fixed.

 

so you would all agree the pulsecharger is the best pipe? thanks for all the help guys

 

NOOOOOOOOOOOOO dont get the pulse charger................get either the Curtis Sparks Racing Exhaust or White Bros Carbon Pro, there the best systems

 

Sparks pipe works real good. HMF is good to but it has an annoying sound. Keep in mind that if you are talking about the same shootout that I read they were putting a lot of emphasis on how loud the pipes were. If they maded much more noise than stock then they pretty much got the boot. If you are dune riding you probably don't care about the noise. That sparks pipe is bad to the bone though. Looks good to already jet hot coated when get it.
