hey guys.. my bike is gettin a overhaul and im putting new exhaust system on it... goonna spend probs 1200 on exhaust would just like to know what ur thoughts are... what systems use have had and how good bad they are thanks

what bike?

kx250f..07



THIS IS NOT A 4 STROKE 2 STROKE BATTLE....

unless your a profssional racer i doubt youll be able to tell the difference between brands pro circuit, fmf etc. ive got pro circuit on my bike and have had no dramas with it....but what can go wrong its an exhaust¿

1200 bucks for an exaust? Are you buying 2 or 3 of them!

I have been told with dirties, the muffler is what makes the most diff. Most new bikes come with pretty sweet headers as is. Id change muffler first, then look into header later on if your still interested in it.

mate 1200 isnt much, you can pay over 2k for a good full system. as for kxf, id go fmf or drd

hit me up if u need a re-jet / tune when u get it

Bloody 4 stroke exhausts....lol. Mate the 250F'are already in a high stae of tune. Putting a aftermarket exhaust system on it might net you some hp up top, but prolly at the expense of midrange - where most of your rding will be done (unless your a pro)....

Si

i agree with fiddy. whatever exhaust you get make shure you get a re tune! also different exhaust systems make power at different rev ranges. so on a 250f i'd be chasing one with more top end power!

cheers for the advice....

If you are paying 2k for an exhaust for a 250 or 450 dirt bike you need to take a good look at yourself.

I doubt anyone on this forum requires to spend that much on their dirty.

For a road bike, 2k is a more acceptable amount.

^ what a idiot. each to there own stick to the nice smooth road fool


ive always been really happy wih FMF but just bought a T4 Procircut system for my yzf250 and im exited to ride it, paid $700 for the slip on so not that bad either.

Thanks for the advice blocparty. But Id like to see anyone on here require 2k for a dirt bike exhaust. The difference is minimal, besides exhaust note.

Some people have more dollars than sense. I would question your ability to reason having a 2k exhaust on a 9k dirtbike.

Man Id love to ride with some people on this forum, just to see if their words match their skill, then watch them flounder and pluck at any excuse possible for their 'apparent bad day'

^^^ haha anyways.. thanking u all again for ur input...think i might just stay stock exhaust till this 1 is shitted.... thought buyin a new exhaust sysytem would improve it a bit but yeaaa by the looks of it it doesnt really.. so thanks guys

i have a ti-4 and i would never get 1 agan looks good and works grate but just brakes maby a t-4

i agree, just get a t4, the weight saving is minimal, power output is the same plus the stainless is stronger than the titanium anyways. i have had 3 titanium pipes before and the next one i buy will be stainless

Get a t4 they are strong and good stay clear of any pipes made from ti.
Try a yank mob called www.btosports.com and you will save at least $400. I get all of my gear, pipes and helmets from them and save big, really fast turn around always within 7 days from the states to your door. Its a simple site to navigate and its all insured postage.

I don't buy anything and I mean anything (car parts bike parts) over $400 from Australia because you get ripped off!!!!!

you are right and wrong! the way i see it is, why do u want a 2k pipe on a road bike when the fucker already does warp speed stock? for the sound is all i would do it for, as for a dirt bike pipe, it depends alot on the bike, some bikes come with verry restrictive systems, and i dont think 4hp gains is minimal! for a bike that only started with like 32hp. for a C grade racer u are probably right, not nessesary, but sometimes yes, as they will give u valuable bottom end added power, wich makes it easier for the club rider to get around and over obsticles.
