I want to purchase a quality sweep exhaust pipe like the one pictured below for my Catalina Scrambler. I do not want the swept back version that is installed on Clubman bikes. It would be nice if the pipe had high quality chrome and the brackets were accurately positioned to fit the bike mounting points!

[img:center][/img]

I did some searching on this site and did find some bad reviews on Armours exhaust pipes in the UK, so they are definitely off the list. I also checked with Feked in the UK and they have the Clubmans pipe but not the Catalina pipe.

I saw some recommendations for Reband and Overlander in OZ, but neither has the desired pipe in their on line catalog.

Can anyone recommend a source?

Barry at Overlander confirmed earlier in the year that they don't have patterns for the off-road Gold Stars or Competition models, but will be quite happy to make some systems if somebody can supply a pattern.

You could try Paul Byrant at http://www.vikingexhaust.com/ This pipe isn't listed But you could ask, I have never heard a bad report about him

Paul does superb work and I was going to suggest him, but as far as I know he only makes pipes for bikes where he has at least a frame and motor (or at least cases, cylinder and head) to fit to.
He'd probably like the excuse to get hold of a Catalina as a business expense, but it may not be practical.

Oddly, I have a scrambles pipe. It's seen a lot of use (i.e. is not beaten up, but does;t have a lot of chrome left on it!), and I'm unsure about the brackets, but it's surplus to requirements. It's in England and I'm not, but will be in a week's time. I can get some photos and measurements if you are interested.

Kerry:

Thanks for your offer to provide photos and dimensions.
However, I think I will contact a Catalina owner I know who appears to have a new pipe on his restored bike and see where he purchased it.

My backup plan is to find a custom exhaust fabricator within a couple of hours drive that has a mandrel bender that can make one if I bring him the bike for fitment.

I have a jig that was made from an original Catalina pipe and my original pipe fits it perfectly. It's just finding the right skilled person that has the tools to make one up that won't cost a ton.
The pipe I got last year from Armours for my BB Gold Star is a very nice pipe but the front bracket was off a bit. I wonder if you could get an unchromed blank from them and have the brackets made up to fit.

No problem. Best to go with the known item.

It's available if anyone needs it! I'll get some photos and dimensions anyway while I'm there - I'll be back there, after next week, in mid August.

Kerry, is that a high pipe or low pipe? If it's a high pipe I would definitely be interested.

Barry at Overlander has confirmed that he can make them in stainless steel for around $A230 + postage if I can get him a sample.

I talked to Don Harrell who is a well known restorer of British motorcycles regarding the Catalina exhaust pipe. He entered a beautifully restored Gold Star Scrambler a little over a year ago in a show in San Luis Obispo, CA that had a very nice exhaust pipe.

He said he buys the pipe unchromed with loose brackets not welded to the pipe from Armour Motor Products in the UK. He then fits the pipe, welds on the brackets and has it chromed.
He said the last time he ordered 2 pipes. One pipe fit almost perfectly with minimal tweaking required. The other pipe required considerable trimming and bending to make it fit. This confirms Armour's reputation previously discussed within this forum.

It looks like I will also buy the Armour's unchromed pipe and do my own fitting and chroming.

Where do you get your chrome plating done?

JR:
The local business providing chroming and plating services has gone out of business due to environmental regulations. Another friend who restores bikes uses a plating service in Fresno, CA that has produced mixed results.

When I am ready to have plating done, it appears that I will have to do some networking with fellow restorers and find a new company that is currently providing good quality chroming services.

Having had the same experience here was what prompted the question.
If you find a place, I would appreciate a heads up.
I heard there was one in Kansas or Nebraska that caters to motorcycle folks, but I haven't found out who or where yet.

An update to the Catalina exhaust pipe saga:
My goal is to replicate as near as possible the following picture from the 1963 factory dealer brochure:

[img:center][/img]

Note that the exhaust pipe is the sweep type in front of the engine, (not swept back like the clubman exhaust). An optional factory megaphone is shown mounted at the welded on mounting tab on the frame. I am aware that the illustrations in the brochures often did not match the actual bikes in the showroom!

I ordered and received a BSA B34 Catalina exhaust pipe from Armour Motor Products, Dorset, UK. I was warned in other threads in this forum that the pipes from Armour's often needed some "fitting" before they could be installed... Because of this issue, I ordered the pipe unchromed so the chrome did not crack during the "fitting" process.

Here is a picture of the pipe temporarily mounted in position:

[img:center][/img]

The pipe will indeed require some "fitting"!

The pipe hit the frame downtube, not allowing the end of the pipe to enter the opening in the head.

[img:center][/img]

The end of the pipe at the head will have to be trimmed off "a bit" for the mounting bracket to fit to the mounting stud.

[img:center][/img]

It is not clear what this mounting tab is for, since there is not mounting point anywhere nearby. The only mounting point is the frame tab on the upper left of the picture, up about 2".

[img:center][/img]

In order for this pipe to be fitted it appears that the pipe at the head end will have to be trimmed off about 2" and reshaped to clear the frame tube. The mounting bracket at the engine might fit, but the lower bracket will have to be removed because it has no purpose. I am glad I did not waste any money having it chromed....

There is some good news..
I purchased an open megaphone from Trojan Classic Motorcycles in Australia. They list the item on e-bay for $50 AU. It will cost the same amount for shipping to the US. The workmanship on this piece is excellent and it's dimensions are very close to the original BSA optional megaphone. Here is a picture of it mounted to the pipe:

[img:center][/img]

It has a nice reverse cone and universal mounting bracket.

[img:center][/img]

[img:center][/img]


I do not like the universal mounting bracket and will probably remove it and weld on a custom bracket like the original shown below:

[img:center][/img]

So....it appears that a bit of work is needed to make this new exhaust system happen. I could return the pipe to Armours and demand my money back, but I don't know of anyone else that stocks this pipe. If I fit it, I know I will be happy with the results. Another pipe from someone else may have similar problems.
Ah, the joys of restoring a bike!

Bill,looking at the relative simplicity of the exhaust header pipe bend and offset, you may have done yourself a favour and looked for a pipe fabrication shop in your State, they could,I'm sure, do a far superior job than the junk produced by Armours.
Good luck trying to return the defective piece.

James.

Some Catalina's did not have the loop with the mounting boss but just the boss mounted to the frame which is close to where that back pipe bracket is.

The later Catalina frames, like yours, had the right "passenger footpeg loop" added back to the frame to provide a mounting point for the exhaust. As Bill said, earlier ones had a lug welded on just below where the upper loop joins the frame, i.e. between where your upper loop and "passenger loop" join your frame. It looks like Armours used one of those earlier frames as their model for placing that mounting tab where it is.

That mounting tab is about in the right place for an earlier frame if the portion that rises to the head weren't quite as tall and long. As yours is mounted now the bottom run is lower than it "should" be, and the pipe is a bit too far forward. Reducing the height of the rise would allow the bottom run to be parallel to the frame as well as high enough for the tab on it to reach the (missing) lug. Also, if the portion that enters the head were shorter the other tab would mate with the stud where it should mount which also would bring the rear tab closer to being where it should be to mate with the missing tab.

For what it's worth, 'Cycle World' had a road test of a Catalina of about the vintage of yours and it has the Clubman-style exhaust pipe, which has a mount on the pipe to mate with the lug in the "passenger loop."

We installed a pipe on my GS Catalina project this weekend. The pipe was bought from classicmotorcyclespares.com under part number 42-2835 for 59.99 GDP. It comes chromed. We managed to fit it with modification to the front brace. Other than that the pipe cleared the down tubes (you can pass a thin piece of cardboard between the pipe and the down tube) and attached to the rear mount just fine. The chrome did not crack. If you search the website for the part number it comes up.

Have a 1963 Catalina, came with the swept back pipe and megaphone. My Dads 1960 has the large radius straight pipe. I like what you are doing! My 1963 has what was called the Stepped racing headpipe. I didn't know it existed but more than a half dozen racers from the day pointed it out. Once I saw it, it became obvious. Not sure if it was a race option or all 63's came with that special headpipe.

The 1 7/8" pipe was usually used in conjunction with the GP Carb and GP head. I believe it was standard on the "Competition All Sport". I can't remember if your '63 had the GP or Monobloc Carb but with it's provenance it could have been setup that way from new.

'Back in the Day' many of us thought the 'competition' 1 7/8" head pipe in combo with either the matching OEM mega or straight pipe was the hot set up for our Goldie racers. As Boomer says, I too have only seen it OEM on the '62-'63 Competition models. We've used this set up on our vintage Goldie tracker, but noise regulations at most tracks won't allow unsilenced megas so we use the 1 3/4" silenced mega system.
