Exhaust mods for 2.5L

[barbagris]

E.G. I have traction control on my Gen 1 Rocket .... it's on the R/H handle bar

Paul - I feel you may be mixing terminology. My understanding is that particular item is called Sphincter Control.

Paul...sort out that big tin box under the bike so its m/t or with a crossover in there and then the tune guys can play...

Oh we can do that easy enough Tal Brother, we just have to know that the Tune Boys can play before we start.

I would assume Arrow would produce 1st set of pipes unless they have some kind of agreement with Triumph not to for the 1st 12 or 24 months. Acrapovic may come up with something given the popularity of the bikes.

The Italians (Arrow amongst them) may indeed produce a solution. BUT they will almost certainly say they are RACE ONLY and need a retune. The Slovenians(inc Akra) are also likely to try - but if so few will run without proper tuning. Much depends on HOW triumph designed the engine. Some of the new (designed from scratch for EU5) engines are proving to be VERY hard to mod. The Mfrs are under extreme pressure to make it so.

With all due respect to the R3 - it is a bit of a niche product compared to (as an example - just because I have one, so know)) the KTM LC8c engine bike family. They have been about for two years. Yes there are KTM LC8c tail pipes all over - But then the OEM tailpipe is basically an open pipe anyway. Yes there is a special factory "decat" map for the full Akra decat system - but the decat map is ONLY valid under near constant full throttle conditions. Run it through town and there is a chance of it destroying valves. A power commander WILL keep the engine light firmly ON. And iirc Richard at TTS says the same happens on the R3.

Think about it a bit - Who actually made a HOMOLOGATED R-III pipe? - Zard!. And iirc only Zard.
Most of us run "enthusiast" pipes. Even TORS are not road legal - on paper. And came with Factory tune.

There maybe a way to reflash the ECU with a new map - but so far on many EU5 vehicles this is destroyed/reset when the base map is updated at all. The Bosch ECU used on the KTM is an industry wide device - has been used on cars for years - but until very recently the only way in was to open it up and probe about. An Italian company says they have a way in - but 4K for the basic kit.

I'm not saying nobody will get there - but don't expect a reliable solution to be forthcoming SOON or CHEAP. There are AFR dongles out there - and some seem to work - but so far NOT long term as they can start to drift relative to each other. This may well be a Bosch ECU thing - but it behoves one to be well informed technically before risking 20K

This is the weirdest exhaust I've ever seen. I think will have to wait for some one to.make something good out of this
Just sounds like a sawing machine at the moment ((

I am a little intrigued as to what is inside. Has anybody taken one off to weigh yet? - Tsk! - Why on earth not?!.

Spoke to a manufacturer of custom exhausts in Sommerville.
They seem keen to have a look and perhaps make something for me.
I'll see how we go next few weeks if I'll be allowed to leave the house with this CoronaV sh..t
Perhaps a 3 into 2 to keep on right ride only and make things simple without power loss.

You should see about gutting the insides of the stock exhaust. A little cosmetic incisions on the backside & see what will come of it. From pics that I see you could open it & close it up and no one would be able to tell after a few km. Yet again your going to have to retune the beast. I like the look of these pipes. My ranting.

I wonder what the two welded on tangs are for?

I think they are just for looks to be honest.

IM going to do this to a friends GT this week

Hey Art, How did this turn out. Got some pictures and details for us ?

As I have been saying, these new Rockets don't have separate mufflers.

And don't forget ... it's easy enough to play with the Tin (steel bits) but you still have to tune it.
