300EX EXHAUST ?

300EXRACER · May 14, 2006, 06:12:34 PM

i have a stock muffler on my 300ex but sadly it has a large whole from rust on the end and back fires pretty bad so all im looking to do is buy another stock exhaust

so i went on ebay motors and found a 250EX muffler practically new for cheap but will this fit and correspond with my 300ex head pipe and engine?

let me know if you know anything about the subject

thanks a bunch

Honestly its not worth the money for a new one, just buy a cheap slip-on...

As for your question I do not know if it will fit...

get a dg slip on, cheap, and sounds nice if attached correctly, dont bother buying stock. If moneys not an issues get a curtis sparks

well moneys a huge issue.
i dont have the money for an aftermarket and this pipe is super cheap i just need to know if it will fit.
trust me i would go drop the money on a curtis sparks pipe if i had it.

well since a 300 ex is basically a 250 ex with a different cam, and bore kit, i guess it will fit, but i dont want to give you fasle info and break your new quad so dont go by what i say, find the facts!

i wouldnt think that a 250ex pipe would fit on a 300ex the header is very tiny on the 250, the diameter of the pipe is probly too small

Call a dealer and have them check part numbers for both quads. Then there will be no question.

no i belive that the 300ex engine is actualy a 250X engine with a longer stroke

Correct...

if u went on ebay for a stock muffler, find a used aftermarket pipe for cheap on ebay, it will sound good, look and perform better than the stock pipe

svtbolt04 · May 15, 2006, 09:46:06 PM

The 250ex is a recon motor. The 300ex is not.

svtbolt04 · May 15, 2006, 09:50:52 PM

18310-HM3-000 (300ex muffler)
18300-HN6-000 (250ex muffler)

They are both different. The 300ex has one mounting bracket. The 250ex has two.

250ex wont work.

300EXRACER · May 16, 2006, 03:00:27 AM

aright thanks svtbolt..
that helped a whole bunch.

svtbolt04 · May 16, 2006, 05:07:57 AM

It actually depends on the year of your bike. The ones I had posted were for a 2005.

I think the previous years were one mount, but they arent bent right for a 250ex.

300EXRACER · May 16, 2006, 07:13:41 PM

thats exactly right..the guy at honda said the same thing

300EXRACER · May 17, 2006, 12:08:15 AM

anyone know anyone thats selling a pipe for a 300ex cheap?

svtbolt04 · May 17, 2006, 12:54:38 AM

What do you consider cheap? You can find pipes that people have taken off of their bikes to put on full exhausts.

I would keep checking ebay because I dont think many people here have 300ex's

300EXRACER · May 17, 2006, 01:28:39 AM

yeaa i know.
thats what ive been doing.
i have close to no money.
im looking to spend like 50 bucks on a stock pipe so atleast i can go riding this weekend.

alot of stock pipes on ebay sell for like 20-30$, just keep lookin and u will probly find one, stock pipes sell for cheap, unless u go to the dealer and then they want more than a new aftermarket lol
