After Market Exhaust Questions

TeeDubs · Dec 31, 2011

I've seen alot of guys here using a TTR225 Header and FMF Powercore Turbine 2 mufflers.

Hoping someone that's done this can offer up some advice.

Do you buy this as a complete exhaust system or purchase the TTR Header and a universal slip on seperatley?

Will any TTR exhaust system fit our TW's?

....AND does anyone know where to buy these parts? I've searched the web, ebay, amazon and haven't found what I'm looking for (the nice stainless TTR header with the head guards) PLEASE HELP!!

Thanks,

TEEDUBS

Most of the exhaust mods are the TW specific FMF powercore 4 and the TW specific DG round or oval series for the TW. The FMF Turbine 2 is not TW specific, but some have used it. To date, I do not believe anyone sells a complete aftermarket exhuast for the TW. It also depends on the year of your TW. See the info below for fitment.

The 2007 XT225 is the last year with a stainless header. The OEM part number is the same for the TTR and XT225. It will bolt up to the TW but is a little longer at the section where it attaches to the muffler. It can be purchased new at boats.net or stadium yamaha.

So, to recap:

1. OEM header and TW specific FMF muffler=bolt on. (2003 and beyond)

2. OEM header and TW specific DG muffler=bolt on. (2003 and beyond)

3. TTR 225 stainless header and FMF muffler=bolt on (2003 and beyond)

4. TTR 225 stainless header and DG muffler= cut the header (or add spacers to front and rear) and then bolt on. (2003 and beyond)

5. 2002 and prior bikes: The 2002 and prior bikes have a slightly shorter mounting tab on the frame and a slightly shorter distance between the two mounting points on the muffler. A short spacer is needed to link a 2002 or older OEM header to a FMF or DG muffler made for the TW "all years".

OEM muffler part numbers:

2JX-14711-00-00 1987-2002

2JX-14711-10-00 2003-2012

is there any real gain to using a xt or ttr 225 header pipe on a tw200? is there any noticeable power gain when using an aftermarket exhaust and have a jetted carb and shimmed needle with 225 pipe? does it make the exhaust louder? if you have a 2011 tdub should you get a 225 header from the same year?

lizrdbrth · Dec 31, 2011

It's stainless. Otherwise it's exactly the same as your stock headpipe.

TeeDubs · Dec 31, 2011

Thanks dusty,

My TW is a 1995 and is completely stock right now.

Let me know if this is correct, I should buy the stainless header from a dealership for a TTR or XT225 (years 03-07) then find a slip on muffler that I like?

I've also seen some complete systems for the TTR... would those fit my TW? I'm not afraid of modifying some mounting brackets but I don't have the resources to bend pipes.

here's a pic of my blue beast

Some have reported that they needed to trim an inch or so from the end of the TTR pipe. Ours fit without trimming.

Order the heat shield for the TTR pipe if you care about such things. Your TW shield won't fit. The TTR pipe uses a longer shield with 3 bolts and the spacing is different.

Here are some cheapies

I am not sure re power gain buy but I am sure it makes noise

which the real point

TeeDubs · Jan 1, 2012

I think i got it, here's the schematic from an 01 TT-R225 exhaust

The header (1) sells for $125-180 alone! I'm going to shop around and see if i can find one second hand or something

the part number for the header is 3RW-14611-00-00

I want a shiny one like that Lzrdbrth!

rm_hm · Jan 1, 2012

I kept my eye open and scored one on ebay for 25.00 shipping included last year (2010). Took about a month to find it.

Stainless is sure purdy

Zero power gain, more noisy, sounds like a loud lawn mower (not good). I have installed after market exhaust on all of my motorcycles, but the TW just doesn't need or benefit from exhaust changes, Yamaha did a good job. a jetted carb helps a ton with stock exhaust.

TeeDubs · Jan 3, 2012

Is it really the header or the muffler you put on it though?

1. The TTR full systems will require modifications. How much depends on the 2002 and older or 2003 and newer isuues. To the best of my knowledge, it should only require making spacers, but I do not have 1st hand experience with complete TTR exhausts on the TW. betopimienta mounted a TTR 225 evo on his: http://tw200forum.com/index.php?/topic/256-best-sources-for-exhaust-upgrades/page__st__30

2. Yes you can order the XT225 07 my header (stainless steel) and it will bolt to your tw. It is a little bit longer, and you may or may not need to hacksaw a little off the end depending on which muffler you go with. Go with the stock muffler and you will likely bolt on. Any other exhaust will require spacers/ a little work, but no pipe bending.

3. A third option: Ceramic coating you current exhaust--if it is structurally sound. You can get black or chrome finishes. It will be less expensive than the new header alone! not to mention the heat shield, screws, washers, muffler, jetting, ect. Just a thought. Here is a picture of mine ceramic coated in chrome finish. It actually looks more like steel/aluminum than the color in the pic. Cost was about $60.00. I'm sure it's not going to last as long as an actual stainless part, but it may be a good choice for the cost.

Has anyone just cut out the pea shooter tube ?

Or removed the end a rode around like that and/or dyno?

How about flowing the head ?

lizrdbrth · Jan 4, 2012

There's not much to flow, and you have valves the size of nickels with no room between them to increase their size.

If you wanna make noise drill out the nosecone inside your stocker, rejet the bike and leave the spark arrestor alone.

If you wanna make noise and look pretty go aftermarket.

If you wanna make noise, look pretty and go faster, you need deep pockets, a bunch of time, or another bike. You won't get there by making more noise.

TeeDubs · Jan 5, 2012

Nice, good info dusty! I just got an 04 TTR header on eBay for $15 + s&h it's dirty and rusty but its all there and even has the heat guards

I'll post some before and after pics once I get it and clean it up

rm_hm · Jan 28, 2012

I was wondering if anyone has repacked their powercore 4's yet, and if so which of the many packings did you use?

i have a pretty good exhaust leak where the 2 pipes meet on my stock exhaust...i may just replace whatever is messed up with new stock stuff if the aftermarket stuff is going to be a pain...who knows, maybe i'm just missing a gasket or something

HercJerk · Jan 8, 2013

I just bid on a powercore 4 on eBay. It didn't have an exact model number. Will any powercore 4 work on the tw?

Item 15. It's a thick composite sleeve that acts as a gasket and takes up the space between the two.
