GT550 pipes, especially the outer RH one.

They are like rocking horse sh!t and are made from unobtainium unless you are VERY VERY lucky - and/or rich/stupid.

They are the ones that there has been several posts about recently, and although I managed to buy an early left hand outer BNIB recently, the RH outer is very rare. I have never seen a new one in the last 4 years at less than about £800 and that isn't even funny, some wazzock may have bought it though, I care not.
In my opinion, if someone did, then he should be beaten with it until it looks like a Velocette silencer.
(Google it if you don't know.)

That's the one that gets all the crap and weather when the PO eventually gets tired of the bike, decides he will sort it 'soon' and parks it up on the side stand against a house/barn/shed/whatever so that the top RH pipe gets any weather/snow/crap that the environment decides to send our way before eventually selling the bike on with 'one careful owner' and 'low mileage' bilge that we see so often.
More like one careful owner and several dipsticks. Or just one dipstick owner seemingly from planet Zog.

Unless you are either very lucky or sheer bloody minded as regards originality, then I reckon the best way, is to just buy a set of chambers. It's not as if we are going for top performance out of a 40+ year old bike is it? Is it???
Commercial chamber makers aren't likely to make something that the average joe can't fit to a standard bike and then forget without lots of timing/carb issues are they? No.
They sound good, weigh less than the standard exhausts (which are cloned from a small planet) and cost far less.
That means they will give better performance due to the weight saving, cost less and look good - especially the SS ones which don't rust. Did I mention they cost less? Win, win, win.
My personal preference is that some chambers' down pipes don't look pretty with angles rather than smooth 'swoops' as the original exhausts. You're different? Well, that may or may not make you a bad person - you decide.
I like 'swoops'. This means I may have to have some made to my spec. Still a major cost saving over OEM 3-4.

Oh, by the way, anyone want some standard exhausts with a few dings? Late or early?

3-1 going on the A. don't care if it doesn't perform well at the top end.
I don't spank a 40+ year old as they tend to complain anyway............
Much better than a younger model - they always want bling or 'something' to keep them happy.
You know what I mean.

Yeh, right.
Keep smiling, it beats scowling all the time. :roll: :wink: :lol:

Enjoy the Piper, Alan - I had one on my 380 for a year or so, and a memory springs to mind.

Just after I'd fitted it, I went up the Cat & Fiddle on a lovely spring Sunday. I had yet to pack the baffle properly and it was LOUD.

I stopped at the Cat pub on the way home and it was fairly quiet, not many bikes as it was still a bit early. But shortly after I arrived, a load of bikes came in and parked up - Dukes, Fireblades, you name it. I finished my coffee, walked over to the bike, and kicked it using just a bit more throttle than usual. It lit up first time and I swear EVERYONE in the car park did a startled jump and turned to look in my direction :twisted:

So when you fit it, pack the baffle REALLY tightly because much as I love the sound, it can't half give you a headache after an hour or so :wink:

eBay (US) is covered with decent used stock RH pipes. Most seem to be early models. . It's the left that is hard to find. That's why I patched my current set. True, all the weather hits on the right, but it all ends up dripping and oozing off the left. So the left is wet a lot longer. Hence I have some rust on my left fork and just patched a golf ball size rust hole on the left outer pipe.
On eBay, right hand mufflers are 5 times more common than the lefts. I have been looking every week to replace my outer left, but all I find are early ones.

I managed to get a BNIB LH outer pipe last year. I's in the attic waiting for the rest of the set!

Just managed to get a decent RH outer with slightly loose baffle plates. I intend trying some Belzona or similar to get a decent rattle free zone. We shall see.
I think I will end up with a set of 3-3 spannies, the 3-1 and some standard pipes on the 3 x 550s that I'm doing. Unless I do the oddball 72/3/4/5/6 and put some late separates on that one.
