What I am saying is that these bikes are notoriously lean from the factory. As a qualifier, I do not have a TV (I do want one) and I am not as familiar with its engine management as I am with the first gen MVs. That being said, freeing up air flow through your machine to the extent this appear to will lean out your A/F ratio more and may be detrimental to your engine in the form of higher cylinder temps. Aftermarket exhaust system developed by companies have a liability to the consumer to have done some sort of research to ensure destruction of their machine doesn't occur.

This is seat-of-the-pants. I applaud that; BUT, I would have my A/F ratio checked before embarking on any extended run with this mod. I'm a conservative bastard when it comes to the possibility of buggering up an expensive engine.

See how it performs and then decide on the tuning. May not need anything. Not sure who designed the stock exhaust but that is the most ridiculous design I have ever seen. A flat plate with 2 holes!!??

My experience with after market exhaust systems is; they are designed to sell, with little regard to performance beyond making more noise.
In other words "caveat emptor."

Most reputation aftermarket exhaust companies do hours of research and testing to ensure maximum performance is gained or else they won't be in business very long. Arrow and Termignoni are 2 that come to mind but even those systems will benefit from some tuning on the dyno once installed on a bike since every bike is different

I have yet to see a dyno sheet making a claim of increase by any manufacturer; however I have not looked real hard for them either. So they may be out there.

The whole purpose of doing this mod was to free up up the sound of that lovely triple as the standard pipe really does kill the sound unless you are on full chat .. I was not after any performance gains as I am quite happy how the tv goes but part of me couldn't justify shedding out £1k just to have a nicer sound .. It does worry me that it could make it run too lean . I have had many bikes over the past 30 years and have swapped out standard cans for performance pipes and have never once had any of my bikes re mapped ...
I am also into air cooled 2 stroke scooters and do have a few tuned ones and so I do realise of the importance of having the a/f mixture right especially on these as they are quite prone to blowing up .
May I ask how many people who run the mv triple engine have had their bikes remapped after fitting a non standard exhausts ?..would be interesting to know ??

Understood, you and I ARE on the same page, with regard to opening the can and removing (reconfiguring) its innards.
I would do the same thing, if I can get a hold of a stock can (in good shape) for a cheap price.

I did a similar muffler mod on my last bike.
Which resulted in desirable sound pressure and tone.
But at the expense of low to mid range torque.

There just seems to be no 2nd hand stock exhausts anywhere !!..I did buy a stock virtually brand new dragster rr exhaust for a bargain but it is slightly different in a few ways ..what a waste ..so I took the plunge I cut up my own

I don't like to make mods to my bike that can't be reversed... just in case.
Also, IMO, it helps when selling the bike for it to be 100% stock.

Exhaust now painted and back on bike .. I have been for a quick spin and I'm well pleased ..It's not too noisy ,just a bit deeper on tick over ,it has a nice little burble on over run and on full throttle it only marginally louder than normal .. I am pleased as I was worried it was going to be too loud...so all good .. Next time I'm out I will strap my camera to my bike for a sound sample as today I only dived out in between the showers !!
