Y-Piece and fuel type question

[luga00]

Most of you chaps (and chapesses) seem to opt for the Y-Piece (No Cat) option when customising the exhaust system.

Do you still use unleaded fuel when it's available?

Also, is there a performance difference between using leaded and unleaded?

Please be kind - I'm new to biking :0)

I'm using unleaded real world performance increase well worth the 200 beer vouchers and hour or so's work.

I kept standard can and used the Remus Y.

In my car I can tell the difference between Shell Unleaded and Optimax Unleaded but not on my bike.

Always unleaded.....

.... I've never put leaded in (even by mistake). No point - wrong fuel & more expensive.

Hi,

couple of reason for getting rid of the cat.

On the practical side, it means you can use leaded fuel. This is often the only fuel available in developing countries. Whilst in Europe though, most of still use unleaded. Better for the engine...enviroment, etc, etc.

Getting rid of the cat and putting a Y-piece (1150) or connecting tube (1100) also allows engine gases to flow out more easily, for a better running engine. The bike also ends up sounded like a bike rather than a electric toothbrush.

With regard to performance on leaded or unleaded; I dont think is is much difference, as long as the Ron is the same in fuel. Most good UK fuel has a 97 Ron rating.

thanks

thanks for the replies - I may well go for the y-piece myself if I can get to grips with my conscience over spurting out those naughty emmissions which would have been dealt with by the cat.

My experience with getting rid of the cat was an increase in the tank range in the region of 25-30 miles. A better fuel consumption means lower pollution levels, so maybe that difference might ease your conscience. I certainly sleep soundly at night having dumped the cat on my GS

Dont worry about putting out emissions if you remove the cat. As the cat causes different emissions ... more sulphur for a start.
I believe Cats were forced on the market by governments as a money maker for the manufacturers.

Luga00:
Ditto comment above. Unleaded fuel has no lead so there are many benefits in terms of prevention of lead pollution. Unleaded fuel is, however, far more carcinogenic, containing Benzine amongst other things. Don't let your kids inhale the fumes as you fill your car with unleaded: there's an unproven but highly anecdotal link with leukemia!
Feel slightly appeased by the fact that harm to th ozone layer from automotive pollution is probably less than 0.5% compared to industrial pollution. Feel very very smug that we're squeeky clean compared to the USA!

Just a thought, a cat requires digging up several tons of South Africa, or wherever, to get the platinum, etc. - which I am sure cannot be good for their environment.
