Hmm I got one similar to that in my shed. Hang on I better go check if it's still there.

Oh it's got a rack. DOH !!!
 
That would be with an appropriate air filter as well. Thats 10 of the ponies.
Yes the dyno sheet says K/N pods. The Dyno sheet is from Bats bike I think. The photos are my bike, I have Ramair and 2 inch baffle. All the CES mufflers now have 2-1/4 baffle and make 4 or 5 more horsepower than mine.
 
Immortalised mate. Well done. Mine continues to attract attention daily at the bike shop. What a great thing these headers are!

@bruce aussie, I am about to order a full system that resembles your exact combo. 2" baffles and long muffler, to be silent enough to survive a cop's glance in Europe.
Since you have been using them for a pretty long time already, would you still advise to choose the 2" baffles? Are they audibly silenter, and do you feel there is a perceptible power loss over the 2-1/4?
In other words: Is it worth it, or should I just forget about it and order the 2-1/4s?
I have Ramair already and will have a custom tune done, after fitting the CES system. Thx for advice...
 
The 2 inch is a fair bit quieter than the 2-1/4 and only gives up 4 to 5 hp and they both produce similar torque numbers. Unless you have to win the horsepower wank competition I'd go with the 2 inch. If I was getting a new pipe I'd get the 2 inch again.

Mine got the most attention so far at the Leyburn Sprints. Them old car blokes really appreciate fine craftsman ship and extracting hp from engines.
