TEC 2-1 exhaust on a scram

I didn't find any of this info before I bought them, so here is my first write-up to you guys.

the following represents the extra 600 bucks in quality assurance research you would be paying Arrow that I have done for you.

first off, the scrambler frame does not take that bonnie bolt at the frame for the mid-section (at least on my 2010) as TEC will tell you. The hole is tapped larger and the bolt needs to be longer. i took the one out of the frame and went to home depot and it matched up- sorry, forget which m size. some day i want to get a stainless one from probolts or somebody, so if anyone does that please tell me about it.
the frame is further in on the scram compared to the bonnie, so you need to get the longest one they sell if you go this route. you can still use the bushings from the bonnie or off of the rear TOR bracket.
that also means you have to bend the pipe in a little to accept it and keep constant force on it while you wrench on it. I used a stack of magazines and a rubber mallet to get the proper height, then leaned on it with my body.

the other major thing that nobody knew apparently, is that on the scram; the piston for the rear brake pedal off the master cylinder rests right on top of the pipes. if you aren't paying attention, you will burn through a stainless line like I did, and end up not only replacing the line, but I had to take a dremel to it to slot both the bolt in points up about half an inch. apparently, brake fluid boils at 100 degrees as my locals tell me- and that's a bad thing(tm).

another solution that we were thinking of was taking a bracket to the rear attachment and dropping the silencer an inch or two...

you will have to swap the rear foot pegs, the right hand side one is dropped an inch or two to get below the TORS, which makes these not fit at all. if you have a centerstand, this will annoy you because those inches are right where your foot goes to drop the stand.

you will also have to come up with some kind of bushing or washer combination to keep the silencer on the back of the rear foot peg. i had to put it peg, frame, bushing, silencer, extra lock wash, extra wash, locknut. i am not sure if this is the arrangement on bonnies as I feel like you might put the peg, then the silencer, then the frame, bushing, washer, lock for those bikes. idk /shrug
note, this is all cuz because of the mid section bolt brings the pipes closer to the frame than i feel it should be.

oh ya, and I had to extend the exhaust sensor by 8 inches or so in order to route around the headers down through the oil cooler. it will save you a half hour if you properly label the wires before you cut because triumph in their infinite wisdom used 2 of the same color wire out of the 4.

if i had known what to do i imagine the whole job would have taken 3 or 4 hours to do properly. i had no idea so it took a few days.

all in all, i highly suggest these pipes. they sound great, they give great mid range boost which i can tell by the seat of my pants. no top end gain really, you just get to the top end a little quicker.
fyi i mapped the factory arrow 2-1 map for this.

anywho, enjoy-

doesn't she look so sexy?







Cheers,
-Nate

Thanks for the write up - sounds like a job best left avoided for anyone else, as the system is clearly not designed for the Scrambler. A quick search through the website would have told you that the rear master cylinder arrangement on Scramblers is different from the Bonnie - a lot of people have asked in the past whether Bonnie headers can be put on the Scrambler. The answer is yes, but with a lot of work and it's not realy worth it.

To be frank, the idea of having to jam on an exhaust, with far too much pressure, bending it to get it on and then buggeríng around with the brakes to make it fit? Sounds very dodgy to me and I'd be concerned with the safety of the bike. Shifting footpegs and shimming and then finding out that the centrestand is fouling and the pegs are sitting on the exhaust? Personally I'd take it off, try to sell it in the classifieds here and get something that was designed to fit the bike.

When you bought it, did you ask if it would fit on the Scrambler? If so, what answer did you get from the guy who made it. If he said yes, and it was my hard earned, he'd be getting some return post. If you didn't ask, well fair enough, but I would not leave them on my bike no matter what ot looks like.

Just a quick question - when you keep talking about TORs, do you mean the stock exhaust or the new one you put on?

I asked TEC about the master cylinder clearance as I knew it would be close & as no one had done it I am going for the Staintune at a lot more $$$$

Cheers for the heads up, Terry

You did a great job overcoming the obstacles to adapting those pipes onto your Scrambler. They look good. The more I see this system, the more I like it. I'll probably get a set soon.

@bobbo- perhaps you fail to realize- these pipes are 600 bucks cheaper than the alternative. There is no low pipe "made for the scrambler" the scrambler was made to have high pipes
anything else is an aftermarket jury rig to begin with, which from my experience, will always take a little bit of shifting and dodging.

the Triumph Off Roads is what I thought they called the stock pipes that came on the scram

@TerryK- which staintunes? the only other 2-1 low options afaik are zards or arrows.

@Easy13- thanks man- that's exactly how I felt

Nate, I know that those pipes are cheap - there's been a few threads about TEC stuff and how much cheaper they are than the Arrows stuff that they copy. I also know that there are a few 2-1 systems for Scrams. Zard (Cross and Low), Arrows, Shark, D&D do a 2-2, although I thought the Staintunes were just high pipes. So clearly, there is stuff on the market out there and they don't all need buggering about with, but you've done it, you're happy and that's great. I'm not exactly new to the Scrambler you know.



Here's the Shark btw. €531 + VAT, according to their website. Which I grant you is still more than the €250 that the TEC costs, but it is at least legal (big problem here in Germany), half the price of Arrows or Zard and comes from a proper exhaust manufacturer.

The Staintunes are a copy of the OEM pipes & legal here in Australia but @ $1200 au not cheap, the TEC is $300 for the 2-1 & $400 for the 2-2
I have Staintunes on the Thruxton & the sound is just right..not loud but a nice grunty roar.

Nate - thanks for the detailed account of your experience with the TEC setup; a cautionary tale for sure! And VERY relevant to me, as I'm currently researching low pipe options for the Scrambler and discovered the TEC website by chance today.

As far as I can tell (and please anyone with any additional info feel free to correct me) the only low systems specifically designed for the Scrambler are the two Zard 2-1 options and the D&D 2-2 system. It looks like all of the other options discussed in this thread need to be "adapted" to fit the Scrambler.

I have been unable to get a definitive answer about the Arrow low 2-1 system, but it seems that the RH footpeg, brake lever and master cylinder clearance issues Nate encountered with the TEC pipes would also be a problem with the Arrow 2-1 low pipe. I say this because the TEC appears to be a very faithful copy of the Arrow in every respect, so any fitment problems with the TEC would also apply to the Arrow (again, if anyone has good information to the contrary, I'd love to hear it).

As for the Shark system - which looks great to me BTW - its really designed for the Bonneville. In fact, the photo that Bobbo attached shows the Shark system on a Bonneville (don't be fooled by the "Scrambler 900" decal!). To work with the Scrambler, an extender piece needs to be added to the collector pipe as well as a longer bracket for attachment to the rear footpeg. With these adapters in place, the Shark pipe will fit a Scrambler but - IMHO -the look of the system is compromised... The muffler is pushed back and outwards, making it look somewhat awkward.

Aren't TEC suppose to come up with a 'new' high pipe exhaust for the Scram?
