OTR Headers
 
Hello

I am very tempted to get a set of OTR headers

Will i see any power gains from them?

Bike allready has akrapovic end cans. K&n stage 1. Dna stage 2. Pc3 so will get a setup to suit.

Thanks

Well i bit the bullet and ordered a set. But i must say i am pretty disappointed with the finish.

The welds look crap. The internals are not smooth. The brackets look crap. And section from where it connects to the cylinder to the first flat section are 2 different diameters.

i can return them for a refund so it will cost me the postage i paid originally plus what itll cost me to send it back and the fee my bank charged me for making the payment in euros.

I am a bit angry and annoyed with off-the-road

also randon spots of welds left over it
And the flat tubes are not even flat, i can feel many bumps over them.

Dont blame you. Those welds are awful

They look like they were made on a Friday afternoon. Sorry to hear of the disappointment mate.

smf12 20-06-15 03:07

I wish mtc had made theres allready :(

I can fully understand why you�d be pi55ed off. Everything about them doesn�t inspire confidence.

TBH, aside of the poor workmanship, I cannot see how these are going to give you any performance gain at all? The weld inside the port end is narrowing the cross sectional area and it�s is far from smooth which will restrict flow, then you�ve got the fact it goes from there to 4mm wider pipe back to narrower pipe where it joins the silencer. Unless it�s all wider it ain�t going to make a lot of difference. In any case, a wider diameter header pipe (more flow) will only ever make a positive difference at absolute peak revs when pumping losses are at their greatest.

The OTR blurb on the web site doesn�t make sense either?

�Power headpipe made from stainless-steel with 4mm more section compared to the original. CNC-bent and well constructed headpipe (1) with widened section for better acceleration and top-speed (2). The better gas flow improves noticeably the power and torque (3) compared to the original headpipes. This improves the throttle response as well as the power and torque, especially at the lower rev range (4).
Also the thermal strain of the single cylinder engine is reduced significantly due to the better heat removal and higher gas flow leverl (5).
Fits original and all aftermarket silencers!
About 0.9 kg less than stock headpipe!�


(1) Clearly not!
(2) Unlikely (unless you�re bouncing off the rev limiter all the time!)
(3) Not necessarily as increased gas flow means less exhaust gas velocity (EGV). EGV is more important than peak flow in exhaust tuning. There is a fine balance between the two � get it wrong and you loose power where you need it most.
(4) Wider diameter pipework significantly reduces the torque available at the lower end of the rev range due to reduced EGV.
(5) Heat removal will be worse with lower EGV, because the exhaust gases hang around longer at the exhaust port at all but the highest rpm.

A properly designed and tested header system can make a difference. What I see in your photos doesn�t inspire any confidence that the OTR headers have either been designed or tested properly.

That finish is just pure bull****...
don't they have TIG welders over there..

I wouldn't to impressed either...

Pack them up and send e'm back and take the financial hit and put it down to experience,I've no idea how old you are or how long you have been biking but if this is your first taste of such it most certainly won't be your last at some time or other we have all been there I keep things hanging on the garage wall just to remind me that all that glitters ain't gold.

On a more basic outlook you buy pipes and exhaust's from people who make them not from folk who sell e'm and why I always treat Wunderlich with great suspicion because they don't actually make anything either.

Wow, that is awfull quality. What was their response? I dant imagine they take pride in such a product!

Gas_Up_Lets_Go 20-06-15 16:31

They look like they've been assembled by a week 2 apprentice!! I showed these to my dad (he server his time building rockets), he wasn't very complimentary, mentioned something about having tidier toilet deposits....

I'm not sure it will. I've rejected products from Germany before, and they have always sent me a returns label and picked up the carrier costs. I suspect Germany has improved distance buyer protection.

Contact them, tell them you aren't happy at all with the product, workmanship or performance claims (use Petes very thorough explanation). Tell them you want them to pay for a return and you want a full refund including postage.

However, I have always form OTR good to deal with, but I am in a minority and there are many on here who wouldn't advocate buying from them. Be prepared for a bit of a scrap over your ����. Stand your ground and see what you can get from them

Has OTR responded? Was looking at getting a OTR 2into 1 system.

Thankyou,
 
I was planning to get those to, with the thoughts it may get some extra hp and maybe some sound.
I see it now as a safe for me, thanks for your feedback mate ima keep these headers OG.

ORT 2in1 + touratech pannier rack
 
Hi All,

just bought a 2013 XTR and one of the modification I will do is also the 2in1 OTR exhaust system. I have read some bad reviews here, unfortunately only after I placed and paid the order, though it has been 2 years since then so I hope things have improved.

My main question in the size of the muffer. I wanna get the touratech pannier rack and mouth my mosko backcountry panniers and was wondering, if the size of the muffer will not come in the way of the rack. Or is it the same size as the original muffer?

Many thanks!
Vlad
