Seriously thinking of just doing decat leaving the stock pipe. Might try to get the Akra map added too. Question is, will it void the warranty? I mean, they're akra evo exhaust deletes the cat too.
Not looking for a performance boost... just the most economical way to add more rumble. Plus, maybe the akro map can help with some of the low speed stumbling.Here's the thing. The Akra Evo and Map are stated as RACING USE ONLY (here).
I don't know in the USA - but here TRACK USE of a road vehicle would invalidate any road use warranty right away.
USING TRACK ONLY products on the road is probably an invalidation clause too.
Also - and again this may differ in the USA -
But KTM have openly stated that the R8c was designed from the get go to run with a Cat.
Whereas other engines were not and subsequently modified to do so.
I guess if it blows up - you could quickly refit that cat and try your luck.
But IIRC all engine warranty requires direct AUSTRIAN factory (and reputably COOBER) involvement.
They'll know if the engine was running WRONG.
To date I have not read of any real reason to decat.
That's just my take - and I am not adverse to decatting where it makes a difference - On the big Triumph I gained 30% RWHP. And masses of midrange. But it was/is a big low stressed engine in standard tune.
Would it make much difference on a 790 or 890. My gut says nope.
I'll check with my dealer next time I'm down there. Very disappointing if that's the case. I was hoping to avoid the Power Commander as I really didn't want a "patch" solution.Due to EPA rules, in the U.S. the Akra map update is no longer offered as an option... at all
IF the Apriia sold there is the same as the one sold in the EU (engine and management - wise) then it is going to be locked down. Aprilia USA may decide to assist, but Aprillia won't.The RS660 looks sweet and Aprilia will support the product for the enthusiast community - great dealer support, too.
Dude, we approach this from 2 different ends of the spectrum and that's perfectly OK.Sadly the writing is out there on the wall. I am happy to have lived though a time when modification was possible, and will continue to do so on suitable platforms.
Lest we Forget - Not all Guzzi owners are slow.No offense to your guzzi friend, but performance for that crowd is a rear tire that lasts 20k miles. I am on the opposite end of the spectrum, I only ride on a track and I RIDE (with a little in reserve to make sure I can push my bike into the trailer, not shovel it)
