Howdy guys im only new to this site and i would like to say, HI there TT.
I'm not sure if i am in the right section of the forums, but someone will be able to steer me in the right direction.

What I'm asking is if a pro circuit t-4gp full system made to suit a 06-09 yz450, would fit onto my 2007 wr450.
As im looking around for a new system and i have came across a second handy in good condition.
If you guys think there is a better system out there to suit me, (I manly ride woods and around the river), I would love to hear.

Any help would be great :cry:,

Steve.

Howdy,
I'm sure the P-C exuast is nice but the ones I've heard are super loud and really meant for M-X tracks only.. If you ride where noise is a issue at all you might want to look for a quieter unit..
After being away from the sport for awhile and coming back I'm disappointed by the exuasts out there now, loud and expensive is a bad combo.. I've shopped around and the Leo Vince is the only one that seems to balance this but they don't make one for my old 2003.. bummer. That leaves me with the Lexx (Rocky Mtn house brand but looks nice) and FMF Q4 which seems to get only so so reveiws on quality.

And yes that system should fit your scooter.. But lets get a verification from someone else or call P-C..

stock 07yz450f exhaust is the best system out there IMO. Q4 is nice but not cheap.

Stock pipe, replace the end cap with the pro-moto billet insert. Nice and quiet, plenty of power.

I have done my homework...

Seriously, the best pipe is the 07 YZ450F slip on with the 09' YZ450F header. Then find a cheap spark arrestor on fleabay for a random pipe and fit it inside the endcap of the YZ450F one

Don't waste your time with a PMB cap for the stocker.. it's a heavy pile of garbage with choked up resonance chambers. Mod the YZ450F pipe as seen below.. I used a White Brothers Spark Arrestor end cap

FMF Q4 is nice (had one) but they are $300+ for just the slip on alone.

If you are going to go big $$$ go for the Leo Vince.. better quality than FMF (had both still have the LV)

The LV is super nice, but not quite as quiet as the 07 YZF pipe (I ride secret stash)

thanks for the help guys, i will have to check up more about the leo vince.
what other systems would you guys reccomend, just so i can get abit of an idea what is good and what is rubbish.

Also before i forget, and this may sound stupid, but is the fitment of a yz system on the wr any diiferent to fitting on made for the wr?
cheers for the help :cry:)
