Need Advise On Ti Exhaust

[billyt]

What is the general consensus on the best Titanium exhaust (header & silencer) for the 2014 Repsol?

What are the pros & cons on Mitani Vs Termaggon (spelling)?

How much weight savings could be expected?

Thanks guys.

If you're worried about weight perhaps you bought the wrong bike & should have bought a GasGas

I think the shaving of a few grams here & there is a bit pointless as you can't change the huge frame & it's geometry

Back to exhausts - more importantly will they give you any performance gain ????

The Termignoni silencer weighs 35% less than the standard, the Mitani silencer I'm told weighs 50% less

The Termignoni silencer costs 1100 euro, the Mitani silencer about 500 euro

A guy at our club told me he could feel a definite advantage with the Mitani in comparison to the standard (this is on the previous 250cc 4RT model)

Standard, Mitani or Termignoni ? A definitive answer is coming very soon ;0)

Update and edited today:

Weighted all setups (friends Mitani setup, my standard setup and my Termignoni setup). The figures are not 100%, as I'm using a digital kitchen scale! but they all were weighted with the same scale! same location and one after the other. Shock horror, the Termignoni is actually the lightest, 1.486 kg, the Mitani is next at 1.612 kg and the standard Repsol setup 2.509 kg. That includes all fittings. So as you can see, the Termi is 1.023 kg lighter and the Mitani is 897 g lighter than a standard Repsol setup. (Standard bike (not Repsol) setup, with steel header, steel cover, silencer and plastic cover is 2.553 kg, so 1.067 kg heavier).

I think I can help, as I own a 2014 Repsol and I have owned a Mitani system and now the Termignoni system (although just got the Termi, not ridden with it yet, roll on Sunday). The Mitani is one of the lightest setup and you can choose to run either the standard header, or one of many different size Mitani Titanium headers. It's a good system, sounds nice and depending on which size header and which carbon rear cover you buy (their is 2 options), your looking at about 897 grams weight saving on standard system. Pro's are it's cheaper than a Termi (but it's not much cheaper now the price has recently gone up), the rear carbon cover can be replaced if damaged and you can choose which header you want to use. Con's are it's not as nice looking, especially on the back of the silencer and this is more noticeable on the new 2014 bikes, with their narrower and higher rear mudguards.

The Termignoni is the lightest if you have the Ti header, the complete system is very nice, more stylish (more thought gone into its design), looks like it could of been an original Montesa Honda part. Choice of either Ti header or stainless header, rear silencer has Ti internals and an all carbon outer. 1,023 grams lighter than the standard system if you get the Ti header. Pro's are it's really nice looking, well integrated, lighter than the Mitani and standard systems and sounds lovely, but not loud with the DBk fitted. Con's are it's more vulnerable to damage, as you don't get a separate carbon rear cover (although this can be bought from Mitani as an after market accessory, but adds further to cost and adds 135 g). More expensive than Mitani (but their are deals to be had, if you can buy in bulk, i.e group buy).

Both should give a slight performance increase, although I wouldn't know exactly what. I do know that the bikes that the likes of Laia Sanz and Jonathan Richardson's factory supplied bikes, used the Termignoni, so it might give a worthwhile performance increase (definitely not needed by me ;-)

Billy hope that answers your questions.
