quietest pipe and header combo for 06 yzf450

9 posts in this topic

What are some of the quietest header and pipe combos available for the 2006 yzf450 ? Looking into maybe doing some enduro events this year in the UK and it seems most clubs won't let you run a 4-stroke with a standard pipe. I think but I am not sure its around 94DB now in the UK for enduro events ?. I was looking at the FMF Q4 system and the megabomb header (it says the megabomb can reduce by upto 1.5DB). I myself thought the 2006 yzf450 was quiet in stock form ! Ovuisly it isn't quiet enough ! anyhelp appreciated guys

The LeoVince X3 Enduro exhaust for the WR is suppose to be 94db. It should also fit the YZ, but you will need to check with them to see what year to buy since the YZ and WR frames were different in 06.

+1 for the Leo Vince X3. I have one on my '06 YZ. Well built and comes with differerent inserts for sound and a spark arrestor. Also comes with a nice carbon fiber header guard. Performance is :confused:

Right so the wr450f 2006 leovince x3 enduro pipe is definately 94db and will fit straight onto my 2006 yzf450 ? need to know guys as in the UK our enduro limit is 94DB and they test bikes at every meeting...they won't even allow you to compete on a standard 4-stroke mx bike (i.e. standard pipe) anymore. Just want to make sure as I don't want to have to sell this bike as I really get on with it alot more than I did my 250 smoker. cheers again fellas

In 2006 the WR450F still had the steel frame, so no it won't cross over. Most likely you will need the 07 or 08 WR450F LeoVince X3 Enduro pipe to fit on your 06 YZ450F. The pipe comes with a 94db high-flow insert. I would email LeoVince and ask them which X3 Enduro pipe will fit and also ask them about your sound level concerns.

To tell you the truth, I'm not sure which one mine is as I bought it from a guy off the TT classifieds...but I know that he had it on an '06 YZ. I think they make both an MX version and an offroad version for the YZ.

My buddy has an '08 with the X3 system on it and his header guard is much shorter than mine so maybe mine is the offroad version and his is the MX version :confused:

I say contact Leo Vince. ..they will know for sure!

Ive asked them which year WR Leovince X3 pipe I need to buy to fit my 2006 yzf450.
