jeepman380 Posted June 20, 2006 Report Posted June 20, 2006 Gonna be getting me a '06 YFZ450 tomorrow...i know i know it's a 4-stroke but I got a good price on it...$5500 brand spankin' new still in the crate! Anyway my question is what kinda exhaust and intake you running? Cam-mod or no cam-mod? That kind of stuff. I've looked all around for exhaust reviews to see which one is the best but nobody really gives a good answer plus I trust HQers more than other people. Thanks for your help guys! :beer: Quote
dajogejr Posted June 21, 2006 Report Posted June 21, 2006 Rossier makes a damn good pipe, and the cam mod is a must. I believe it's the exhaust cam that comes 1 tooth retarded from the factory... 5500 is a helluva a deal, I've been contemplating a new 4 stroke for trails and play, and my shee for dunes and drag racing... Think I'm going to wait till the end of the season (live in MI) and pick up a steal if I can.... Quote
shanYE west Posted June 21, 2006 Report Posted June 21, 2006 I use Duncan's FATBOY 4 system and I went with hotcams over the cam mod.. I heard NMotion and Ron Woods are pretty good exhaust systems as well as sparks big core exhausts. I use the pro-flow kit with K&N for intake. Quote
dajogejr Posted June 21, 2006 Report Posted June 21, 2006 I went with hotcams over the cam mod.. True dat...but, the cam mod is free... :beer: Quote
bansheefreestyler Posted June 21, 2006 Report Posted June 21, 2006 im running the dr.d pipe. it throws out alot of good bottom and mid power. wakes the yfz up nice. as for the intake i have a k&n air filter and i cant remember the brand of intake plate. as for the n motion mentioned above they do make good power from what i heard and are hella loud but dont get one. everyone has them and they are way too hyped up. lrds are pretty good pipes from what i hear also and duncan fat boys Quote
txblueshee Posted June 21, 2006 Report Posted June 21, 2006 Hmf makes a solid yfz pipe... it won't cost you 800$ either... Mike Quote
speedfreak350 Posted June 21, 2006 Report Posted June 21, 2006 You got to pay for quality just like anyhting else. All 450's around here that are what i consider fast or atleast close to me are runnin either the sparks or ron woods and i belive ron woods it bout the best u can buy. As for FMF i wouldnt even consider them for a 4-stoke they just aint got the hit that they do on the ol twin 350, of course anyhtings better than stock though. :beer: also HMF is a great pipe for any 4 stroke and hes right there not quite as pricey as the 2 I mentioned.

Big Blue Posted June 21, 2006 Report Posted June 21, 2006 im running the dr.d pipe. it throws out alot of good bottom and mid power. wakes the yfz up nice. as for the intake i have a k&n air filter and i cant remember the brand of intake plate. as for the n motion mentioned above they do make good power from what i heard and are hella loud but dont get one. everyone has them and they are way too hyped up. lrds are pretty good pipes from what i hear also and duncan fat boys How are the nmotions hyped up? the guy that builds them puts just as much time into them as any of the others. Sent you a PM jeepman. Quote
it's stolen Posted June 21, 2006 Report Posted June 21, 2006 my brother has a yoshamira pipe, pro flow plate with a k&n, hot cams and aftermarket ignition. I dont remember what brand the cdi is. we have installed a WR crank, 2mm big bore and he has had the head ported. it runs really good but i hear the ron woods pipe would make more power Quote
bansheefreestyler Posted June 22, 2006 Report Posted June 22, 2006 n motion is hyped up because everyone says they are the best and im sure they do make good power but are not the best. they are too loud for the nationals so you cant run them there. go over to yfzcentral and read some posts. someone will post pics of their new yfz and will ask what pipe should i get and everyone says nmotion and that is the only pipe they have ever ran. there are just a good of pipes out there but nmotions are the new style so EVERYONE has to have one Quote
helldriver Posted June 22, 2006 Report Posted June 22, 2006 (edited) you shouild wait until the 07s come out, they are gonna have some more major upgrades,, bill ballance has 2 already a modded cam is one of the upgrades{ or to be rummored } and the others??? I run the curtis sparks pipe,, and it awesome Edited June 22, 2006 by helldriver Quote
racer Posted June 22, 2006 Report Posted June 22, 2006 make sure your battery is in good condition if you do the cam mod, or change them altogether. it makes it a little harder to crank over and will kill a battery that didnt bring its A-game. Quote
puddle jumper Posted June 22, 2006 Report Posted June 22, 2006 ya,rotax pipes are the best imo.you cant go wrong with any woods products :thumb: Quote
tithead Posted June 22, 2006 Report Posted June 22, 2006 i have a micron pipe..... alot of power comes out of them but there not the strongest. i have my air box lid thrown to f*ck i use foam air filters. i dont run the cam mod. iv heard that a few people in the pits say they dont really notice much difference. it depends what riding your doing... i race in mx.
