I have a 2005 TA200 Phantom and would like to get some custom parts, starting with a nice sounding exhaust. Does anyone know where to buy these bits ion Thailand, I am in the North East but could order or maybe travel.

Or maybe my existing box could be modified, so an expert in that field perhaps?

Thanks

I was searching around on google ai saw several sites here in Thailand try googleing honda pahntom accessories.

Moe,

Just curious have you tried ridding around instead of googling around?

Yes and no, I couldn't find anything. There are a few car exhaust companies here who I thought may do a mod, but back pressure it quite important on small engines and thought they may screw up the already meagre performance.

My down pipe is looking a bit sorry so may experiment with this exhaust.

By the way what is "Ridding" as opposed to Googling, or was that a misspell by your mate?

A word of warning, a new exhaust for the Phantom is 12,000 Baht. My down pipe went brown and sorry looking, I brought it back by using well worn scotchbrite nicked from the kitchen, WD40 and about 40 minutes worth of elbow grease. It needs a quick 5 minute rub down about once a month or so to keep it looking decent.

No, the backpressure is only important on 2-stroke bikes/engines.

Must be why SuperTrapp make tuneable mufflers for 4-stroke bikes

Please provide a link/source, where "SuperTrapp" (?) seriously explains the importance of "back-pressure" for 4-stroke bikes/exhausts....

4-stroke engines need everything, but never a "back-pressure effect", it's just a myth.

Very good 4-stroke exhausts are designed to create a "suction-effect".

Please read this

The article you quote is flawed in a way because it states that "Back pressure in it's most extreme form can lead to reversion of the exhaust stream - that is to say the exhaust flows backwards, which is not good"

If exhaust reversion is not good how do you propose to create a "suction-effect" ? So by providing a link, if you read it, you are agreeing that 4-stroke exhausts need back pressure.

Since you are the one suggesting that "back pressure" is important for 2-stokes (to quote your comment) please provide a link/source that explains the importance of "back-pressure" for 2-stroke bikes/exhausts....Very good 2-stroke exhausts are designed to create a "suction-effect" like your liked article good exhausts are designed to create a return pulse. A by product of which is back pressure designed into the system. let us also not forget that the bike in question is a single cylinder bike.

I am not sure how many 2-stroke exhausts you have bought but as an ex-kart racer I have bought many both short track and long track ones.

Should the previous statement lead you to think that I have only been involved with high performance two-strokes, I have previously built a few 4-stroke race engines but to provide such links would invalidate my nomme de plume which after all is part of the fun on having one.

If back pressure or a returning wave is not important for 4-stroke engines why did Red Bull fit a Helmholtz resonator to its F1 exhaust emulating many other F1 teams. These have become all the rage recently for single cylinder dirt bike exhausts. Of course they only work at a certain RPM and not across the whole rev range. (Added because I sell exhausts which do not have them )

Everything to do with exhaust design is a compromise if you wish to run your single cylinder 4-stroke bike with an open pipe please feel free to do so but it will suffer a drop in low speed torque. Large North American V twins get away with this because it doesn't matter if they give away a little low end as that is what they are primarily designed for.

If you would like to borrow Roy Bacon's book on 2-stroke exhausts I will be happy to loan it to you and if you wish Cesare Bossaglia's book on 2-stroke high performance engine design although this is more an expose rather than a practical manual. I offer these as often it is not possible to glean everything from the internet.

I do not wish to enter into a protracted discussion as that would break one of my personal rules see signature below.

Nice animated gif, which shows the "back-pressure" effect on a 2-stroke engine

Moe,

Yes Neal on rare ocassions when everything is perfect I will go for a put.
