Best Aftermarket exhaust for TTR250
Permalink  
 

I just bought a very nice 2002 TTR250 in great shape and I was wondering if an aftermarket pipe would really help, or should I just open up the stock pipe?  I don't mind spending a little money if it truly makes a difference, but I don't care about the weight reduction and appearance, etc.  I would only want it for performance, and if it is not too painfully loud.  I appreciate all replies.  Thanks!

I have a barrett exhaust. I definitely reccomend opening them up and getting rid of the restrictor in the header pipe. They rev alot more freely and the weight difference would be prob 5 kg.

The holy grail for me.

Motad went bust and Roy at OSS made me a great prototype only to mess up the 6 he manufactured for me and I had to send them back!

Would appreciate some photos of your aftermarket exhaust and how easily they fitted to the header pipe and most importantly how loud / quite are they?

Easy to put a DB reading app on your phone and hold .5m away at a 45% angle from the business end of the exhaust.

May be better for me to talk to another manufacturer, rather than having my own made up.

Steve

Real shame about Motad as their silencers were beautifully made, totally stainless steel, much lighter than the standard box and not too loud. A hard act to follow and you will do well to find a match.....

 I have a Staintune as well, fitted a different baffle from Staintune & it's better, I do get better power & use less fuel than my mate with a DG pipe

FMF Powercore on mine is really light and looks great but is much, much too loud as stock so I have had to make a long baffle to fit, which probably negates any gains from being free breathing to start with. Real shame about Motad going out of business, great products and service.

Steve.my tk has a note to it but not obnoxious.
It is well built and fit was perfect.
15min fit.
I dont think it was much lighter.but looks like it will take a hits no probs.
I think it has a 94db stamp on it.

I've got a Pro Circuit T4 slip on on my 2002, with the down-angled "silencer" which makes it less than ear splitting. Assuming you have a US model we have the same bikes. I'd buy it again, runs smoother, good and loud but not bad.

Stupid question but I haven't found time to figure this out: does the US model include the restrictor in the header pipe? So far as I can tell the US version does not have the restrictor, but I'm easily confused.

I would like to know if there is a restrictor plate in the header pipe too. Obviously that would make a big difference. I opened the air box, and drilled holes in the rear baffle of my stock pipe last night. It is louder, but not too bad. I'm sure I doubled the air intake and exhaust ports and hopefully it will help. I will test it today. I may need to make it a little richer with more air coming in. Hopefully, there's a couple of needle clips available to adjust. Thanks everyone for the replies!

See http://www.ttr250.com/#exhaust and http://www.ttr250.com/detail+of+restrictor.jpg 

The general opinion is that the US TTRs don't have the restrictor but it only takes a couple of minutes to whip off the silencer to check wink

Thanks Brian that was my conclusion when I tried to figure it out a few years ago, I'll find some time to unslip the slipon and see what's in there.

JCW opening the air intake is key from my experience, yes on the needle clips, and with the opened box and slip on I'm good at the stock needle setting (middle).

Just picked up a 2005 and wondering, where is this restrictor located? At the end of the header pipe in front of slip on? Thanks.

The factory restritor is in the back end of the engine pipe . In Ozzy bikes the USA may not have had them 

There is a good gain cleaning up the weld on the front of the header as well. The weld is about 1mm high all round and rough
