Not concerned about noise...............

Procircuit baby!!!!!! Very aggressive and adds a crap load of power everywhere.

I got the Ti GP lowboy system so bottom and mid are stronger than top.

White bro's carbon pro II supposed to be awesome too, but have to keep on top of keeping the packing good. A very reputable shop told me that carbon pro II made more power than Aluminium pro II. I thought they were the same?

The PC T4 is flat out OBNOXIOUSLY loud. Works well but stupidly loud. I vote for the YOSH so you can toss in the TEC and quiet it down when needed.

The Q2 and power bomb arent all that bad for a quiet system. :applause:

Only for other people, the noise is behind you!

The noise does get to you a bit after a while (once the novelty of tripling your horsepower wears off :applause:), but you can get different inserts for the endcap to tone it down a few dB. I brought mine for power, not to be quiet.

I would like to see FMF bring out a twin piper for yamaha soon, I have read great things about them on CRF450R and RMZ450, like more hp than their single systems and just a bit louder than stock. You will need a fat wallet though!

I put a yosh full system on mine and there is not one complaint i have about it! It is extremely well designed, it can be loud if you want or just pop in the insert and bring the db's down.

With the jetting right and all the mods done, my bike just bloody rips@!!!

My Yamaha mechaic who is also a test rider recommended FMF 4.1 Complete System and I am purchasing for under $700. He prefers FMF over the YOSH because it does not flatten out at either medium or high range acceleration. YOSH pulls better in the low range, but frankly, my style of riding is desert high speed .

Go FMF!

Do you ride public roads with these pipes? Or deserts? :applause:

I think my FMF q is too loud without the insert, for road riding.. It`s cool to ride though..

What??? you definately wouldn't want one of these babies!

I ride mine on the road, but it is just to get to the tracks or if I couldn't be bothered riding through the bush anymore.

It is not a daily commuter! That is just a waste of a bike.

That's my excuse :ride:

they are appearently allowed to because they didn't have mufflers back in the day. The new ones have to run mufflers, but they don't do squat. :applause:

I am all about respecting the noise restrictions to keep our riding areas open, but if people are worried about noise they need to look to the Harley's. They are just plain OBNOXIOUS!!!!!!!

Its not the people on the highway complaining about the noise its the hikers, horses and mtn. bikers in the woods. Keep them quiet and keep areas open.

I have a FMF Q with power bomb header great power and quiet.

You my friend are elgible for the Darwin Award.

Your in Cali and say you don't care about noise? If I ran across an idiot like you, I'd let my wife bioch slap you till your other testacle droped finally.

Your just plain stupid, and the root of our shrinking riding lands. Do us all a favor and huck it over a tripple without making it all the way......... :bonk:

I'm normally laid back, but chumps like you bring out the worst in me......... That's all I gotta say before............... :applause:
