And they will quieten the bike down?

Are the ones on the bike now original Yamaha cans?

What was your question Scott?

[Mr OCD]

Sorry guys. I decided I would just make my own bloody mind up for once.

Question was about Leo Vince exhausts. i.e. whether they are any good and how they compare to Akras / Arrows.

[Fleegle]

I think you should go for Graves

I still have a Leo Vince off my Fireblade and can say they are not in the same league as Akras.

Would have loved them. Sourcing in the UK is next to impossible, so they have to come from the US which with import is around £1500 ... I cannot justify that kind of money for a couple of end cans.

A few people have had them on the crossplane R1 ... apparently sound better than the Akras, but regardless at the end of the day they are all hollow tubes so I think it's a case of pick what you think looks the best as they will all perform similar.

My main concern is reducing the noise for track days.

The existing leo vince decat and standard cans with A&R baffle kit are too loud, hence the change.

Quality wise I'd probably agree although haven't seen Leo's myself, but the Akra's are over double the price so struggling to justify for my need which being honest is to reduce noise levels with baffles fitted and look pretty.

Akras pass noise testing with a de cat and baffles fitted.

You had the chance of a mint pair last year that used to belong to me. You should have snapped Paul's hand off you tight git.

Didn’t have the money spare at the time. I’d just bought the bike which wiped me out due to the bks with the Fireblade.

Or there's Microns with Ti headers

What kind of baffles?

It looks to me like manufacturers use the catalyser in place of baffling the exhausts now so a decat ups the noise massively. And the end cap/baffle that a lot of aftermarket cans come with usually screws the performance because it's like sticking a cork in the end. The inverted cone type two-part baffle I had in a Yoshimura that fitted pre-can didn't cripple the performance but didn't make it much quieter either.

Headers are Ti as standard.

My 04 and 09 R1 Akrapovic cans came with removable baffles, my o4 R1 never needed them for track but the 09 wouldn't pass without baffles. Both bikes had de cats,

MHP Exhausts or Seton tuning.

Agreed... no way in hell is my R1 passing noise testing as it sits...

Gavia would moan like an old woman about the noise the R1 makes at the moment

Anyway I've ordered Leo Vince EVO's, hence the post delete as I decided I'd find out for myself. They will be here Monday. Ordered from Moto GB who have been absolutely superb answering all my questions and provided excellent customer support.

I suggested Pipewerx last time. They’re local and do very good pipes that don’t need baffles even on a decat to get through noise testing. I’ve got one fitted on my old trackbike, as I’d rather know I’m getting on than pissing about with baffles at a track.

Blimey, is Mark Hill still welding bends up ?

Wheres he based now ? He built me a great 4-2-1 for my GSXR motoreed EFE streetfighter many years ago.....

I know mate, but they look dreadful on the R1... I did look at them.

No they don't!
