Will this mess up the power of my bike?

and do you reckon it'd fit?

I'm guessing that they're the same bore as the standard TRX headers. I'm just wondering, that's all

As the cylinders are the same then I'd say they are bound to fit.

But you'd have to make up some pipework to connect to ths can. TRX is 2 into 2 as standard, as you know.

Thanks. I might give it a try when pay day comes around Not the same as a 2-1 Akrapovic, I know but should still save a few kg off the bike

Kedo has a set for TDM wich are supposed to give +2hp at 5k something...

I assume that you've seen the advert from Philk?

Compared to a stock TDM that is. I also thought that I've read somewhere the "bigger" diameter TDM headers are the same as a TRX stock (38 mm). In other words, the standard headers of a TDM are even thinner than the ones from a TRX. But I'm not sure about this.

Yes, but £700 is a fair chunk more than £95...

Sandy Bike Spares also do a set...

Be interested what result you come up with Kayla.. Had a local manufacturer make up a set of big bore headers n 2 into 1 and found just on 87 horseees at the rear with the fcr's n bellmouths..

Sounds good Cobba....post a piccy Maybe in a more suitable forum or we may get in trouble by the powers that be for diverting off topic I would be interested to see however...

Whoa!!!!

TDM headers won't fit a TRX!

The TRX engine is canted slightly further forward in the frame compared to a TDM, so the headers are shaped (curved) differently.

I've got both bikes, and tried to swap the headers over "just to see" and take it from me, they are not interchangeable. If you fit the TDM headers to a TRX motor in the TRX frame, then the outlet of the headers (which is a single outlet on the TDM, not twin outlets like the TRX) is hard up against the starter motor behind the sump. TRX headers won't even go under a TDM, as they foul on everything under the engine, left pipe wants to be where the chain is, right side hits the frame....

dont touch the headers from sandybike spares
it took me 2 different sets to find ones that fitted and they are already rusty!
yes rusty, shite quality 'stainless' and they have cracked after a year on the bike
