Motorcycle Race Cans
Discussion
There now follows a gratuitous plug for a new kid on block.
My only connection with the company is that I supply them with a few of their fixings, but I have known the guy behind it personally for a few years and know that when any company is in its infancy they need all the help they can get to establish themselves. Once they are up, running, and turning a profit they must stand on their own feet but hopefully Ted will allow this one.
Barabbas Exhausts are a brand new company making slip on race cans and I can honestly say the quality of the product is beyond question. John Campbell who has set is up has been around motorcycle products for a good 40 years he lives and breaths bikes but has been plagued over the years with "bad luck" in business. I have personally seen photographs of some of his old developments that included magnesium alloy wheels from the early seventies before any major manufacturer had even thought of them, and a product from the same era that can only be described as a spitting image of an EXUP valve long before it got snapped up and patented by Yamaha. The guy is an engineering genius when it comes to bikes and I would not hesitate for a second to say his cans are the best you get, they may not have an Acropovic name on the side (but then TVR's don't have a Porsche badge) Rest assured I personnaly would stake my credibility on this recommend any one that buys a Barrabas exhaust will be getting the best UK manufactured quality and engineering possible.

Ted sorry if this causes offence it's not intended to and I know it's effectively an advert for a company which aren't paying for the privilege but as I said they are brand new, hard up and need a helping hand. They originally set themselves up in the Isle of Man last spring with the idea of launching at the TT, Foot and Mouth then resulted in the TT being cancelled and very nearly bankrupted them. As a result John had to accept that business on the Island would not be enough alone to support the company (with no TT) and has had to move back to the mainland. Thats the level of bad luck the guy has.

What's the construction? The packing in my lovely set of Art cans went off in less than a year and they lost their deep note.
I got them because of a review that said they sounded good, very resistant to corrosion and might just get away with a track day.
Three years on they are too harsh, much louder and I've put the manufacturers cans back on.

The problem with ART cans is they are rivetted togeather and of v thin wall thickness st/st (but they are cheap) Barabbas are of a bolted construction so they can be taken apart and repacked. I'm sure John would either supply the wadding so you can do it yourself or offer a repack service.
Packing is important as you will actually lose power as it breaks down, you'll also find that a quality can has st/st wire wool wrapped around the perforated tube before the actual wadding to protect it a bit and increase life span. But obviously this costs and is missed out on cheaper cans.

Stupid question - Why doesn't anyone appear to be selling a race can which does not require periodic repacking ?
Would a double skinned pipe with baffles between the two skins work in a similar way to using packing between the two skins ? Presumably not or someone would have done it by now....

They do and its called original equipment.
Race cans are free flowing hence put simple all you have is a perforated tube through a sleeve with the void filled with a absorbing packing material. The idea is to get the exhaust gases away from the engine as quickly and smoothly as possible hence giving better performance, if you put in baffles etc you inhibit this process and decrease performance OE equipment is a compromise between sound absorbtion, emmisions, and longivity. Race cans are focused on performance only. The density of the packing is important because by giving a denser surround the gases flow easier but in all cases over time this packing will break down due to the level of resonance created, (the worst cases being in the big v twins that can destroy cheap end cans in a thousand miles)

I ordered a can off the carbon can co. and it arrived thursday got my bike back today 
have just gone to fit it and the f**king thing dont fit plus no bolts to fit it with 
anyone else used them cos if they are this bad i'll get a refund and go elsewhere .Mel can you reccommend anyone ? 
Carbon can co. you have an angry call coming wendsday morning

I brought A Quill Powerflow road legal can last year and its still ok so far with one winter out of the way.
It sounds pretty quiet on tick over but once you open it up it sounds pretty good(but not quite race can burble).
I have had quit a few comments on how it sounds and some people have thought it wasnt a road legal buy the noise it was putting out.
And apparently gives a couple of more hp but i havnt noticed it that much i think youd have to be a racer to feel that.
Went for a road legal as dont need them points on me licence as i need it for a living and the ins cost a bad enough without points

I didn't mean baffles across the pipe
What I meant was - if you were to replace the packing with something that does not degrade with use; wouldn't this be better for the biker and a selling point for the pipe?
Mentioning baffles wasn't such a hot idea though, sorry for the confusion.

I'll have a look at these - Cheers

How often do they need re-packing? My Ducati hasn't managed to destroy it's Termi's yet after about 7000 miles and they still seem OK (mind you they weren't what you'd call "cheap"!) Although the whole clutch assembly "shot" out thru' the cover and chewed up the fairing on Friday - seems the retaining nut came undone - Bugger!

...has anyone actually been done for a noisey can? what happens? what if you put it back on again?
Carl
Yes, Fine and told to put it right ( £20 at least it was a few years ago - probably 5yrs porridge by now!)but Plod didn't actually check if it had been put right.
AFAIK if you put it back on it's the same penalty again
