Chinese Exhaust for CRF230f - Any parts interchangeable..???

[WERNER1]

Hey guys quick question(s)

On the Chinese exhaust systems that are on ebay for like 100 bucks (See link) ... are those parts interchangeable with any of the factory exhaust?....say like use the Chinese Header, but the factory muffler or something? Just curious as I can pick up a system pretty cheap and thought I'd try it out.

Also what is the sound of the Chinese set up vs. the factory "Un-corked" sound? (I like the uncorked sound )

One thing that concerns me is the lack of a head shield on the header pipe....are there any "good" aftermarket heat shield options out theres?

Thanks, and here's a link to what I'm referring to:

I would stay away from items from China as their materials and welding are usually not very good.

Stick with stock or go with ProCircuit or Yoshimura is what I would do.  Expect small changes to power and to lose 2 or 3 pounds at most.

Stock pipe with FMF head pipe (or Powroll) and EO PoweRing is very good but not cheap.  Better off with cam and piston and Procom CDI.

WERNER1..

The first answer I would give is that the Chinese exhaust is not compatible with other tubes .. But my memory would fail .. I could check to give you a correct answer ..

In my opinion the sound is too uncorked and noisy

Ok thanks for the replies guys! I think I'm going to pass on the exhaust for now,.. I like the sound of the Factory "Uncorked" set up and I'm sure it's probably flowing "decent"? ... not looking to build a race bike or anything.. ?

This is..

[WERNER1]

I really thought the sound of yours in your videos was nice and mellow,.. which I like actually.. It seems the older I get the quieter I like my exhaust, and I really like those Deep tones verses loud poppy and cracking stuff...

I worked to modify the Chinese exhaust ... which otherwise sounds too loud and without having a power that justifies the loud noise

[VortecCPI]

So total cost of Chinese system plus how many hours spent multiplied by your normal compensation rate multiplied by 2.5 = what?

(2.5 = the average of 2 and 3, which is what a consultant generally demands and what your personal time is worth compared to your paid time)

I know that but I was just wondering...  I did the cam and piston in a few hours...

A few hours struggling with great pleasure, no?

I used a Chinese header pipe on a 2004 CRF450R and it worked great. No problems with fit or quality of welds

[WERNER1]

Does that mean you used it in conjunction with the Stock muffler?

Why bother changing the head pipe ? I wouldn't unless you were doing a full exhaust , anyway.

Not currently using any chinese parts (knowingly) on my bike but here's the thing.... Many of these "Quality" parts we use are already outsourced to China. I think the issue is more likely that not all Chinese manufacturers live up to the same quality standards as the others.

Because Chuck has found during testing a larger head pipe adds TQ in low-mid area with stock exhaust, as have many CRF230 riders.

Quite a gamble with your time and money...  B&W moved from Mexico to China years ago...  Now back in Mexico...  Speaks volumes...

I would try the Chinese exhaust, although I doubt there is that much power improvement over an uncorked "straight through" OEM exhaust or even FMF etc.

China is where Japan was in the 1970s. In the 60s "made in Japan" was synonymous with junk. By the 80s they were the best. I've gotten some Chinese stuff that was excellent, and some that was junk. I love the design on this exhaust system.
