Core cans

[Duke Konan]

I've been looking around for options re after market cans but simply can't get over the fact that I really like the way the stock cans look on my S2R. The only others that I like are the Sil Moto Megapipes but can't justify spending the £500-600 when I like the look of my stock cans better. So, I figure - core the stock cans! Which leads to my questions directed at those more knowledgeable than myself!

1. Will coring the cans only make them louder or is it likely to have a beneficial effect on the flow of exhaust gases? Presumably more noise = less restrictions on air flow?

2. If I decide I want them cored, where can I have this done and how much should I expect to pay? I'm pretty handy myself but I don't have the tools to open up and seal the cans and given that it could impact the way the bike rides, isn't something I want to attempt myself in case I screw it up!

My S2R has cored cans, but as I didn't do it myself, I can only answer question 1.

They are very loud, and combined with a decat pipe and open airbox, it certainly makes a difference to the power.

Cheers Sazza. Where did you have em done?

You really dont need any specialist tools to do it yourself.
The only thing I'd recommend is a small 'dremel' style modellers drill as they have very small diameter cutting wheels, my drill was a cheapo one from woolworths but it was good enough to do what I wanted it to.
I used a hacksaw to cut through the insides of mine, I would now use an angle grinder if you can borrow one as it'll save a lot of time.

They are quite loud BTW.
Do you still have the cat on yours?, as getting rid of that actually frees up more power and sounds nice on its own.

I did mine on my 696 last week, very similar process. one bit of advise is the neater you cut the barrel and the least material you remove will make it easier for the welding. If you can remove the sleeve like you can from the 696 with out cutting anything then i would use a chop saw with a fine metal blade on it and cut each pipe twice or with and angle grinder with fine blade and hack saw for the internal tube; once at the exhaust end and then another just below the baffle. my baffles were tacked on from the out side so had to grind these away before tapping the baffles out.

I only took the baffles out and left the cat in so no need to insert an additional perforated tube and wadding for back pressure (correct me if i have got that wrong for these cans?). It took my fabricaters about 1.5-2 hours to weld both back together, 4 welds in all, i can weld a little but this was a bit past my skills and would leave this up to the proffs to get it straight and airtight.

yours are slightly different but hope this may help a little.

it's not technically difficult, but the best advice I can give based on my experience is give yourself lots of time & don't rush the job. The top can is the trickiest because you need to leave the strip of stainless steel inside to which the exhaust guard mounts. The Ducati up north guide is spot on.
