So where do I buy a big bore Jota exhaust system these days? Downpipes, collector and "silencers". Stainless or chromed steel.
 
Keihan is easy the best of the lot I've seen available in the UK, they very nearly fit, can still take a few hours and a bit of welding to get them to fit perfectly however.

Big bore? Small bore? Wild boar?

If they need "a bit of welding" the phrases "free from minor defects" and "fit for purpose" would come to mind and Keihan would receive a bill from my friendly local welder.....
 
It's sad but true H none of them seem to be a great fit. i've had to cut and weld mine to stop it straining the rear rubber mounts . Wolfgangs downpipes do not follow the originals smooth curve, rather a series of bends. Spoils the look IMHO. Also tried a set of downpipes from Ralph.... didn't fit sent them back. Had a set from Armours years ago. They looked really shit and I gave them away. soory wasn't much help was it ?      Tim
 
I have mine from OCT stainles , 40mm heders , open Jota pipes . Wery nice with minimum adjustment on heders , have to hummer one a bit becouse it was tuching frame .
 
You could go custom made.

Bro gets his bends made to order at OJZ then welds them up himself, have a look at the headers he knocked up for the Jag. (Thats OJZ not Simon)

Or try N. Parker, I believe he's doing a fair amount of business for the classic community now.

And if you need any tuning work done to the bike have a word with Dave at D&M next door, really nice guy.

Good info. I don't like the "series of bends" approach - I'd rather have the brutal two bends on the downpipes and stuff the curve in this particular case. Good info on the Armours too.

Hi
i think Keihan would be sending that bill straight back to you,if you are not happy with the fit you should send the item straight back,once you have welded and tweaked the system you would have no claim.
As Keith said Keihan are probably the best available for the money.

I think the set I got from Ralph where Keihan and they did look nice , the problem was the bend wasn't quite tight enoungh which drops the rear of the collector on the centre stand . With the 180 there isn't much margin for error if you want the zorst to miss the frame rail and the stand. Bending them was a no go without the kit and I didn't want to chop the flanges and reweld them. On a positive note i had some silencers from Armours and they were fine but that was back in 87 ish.

well Neale ,, being a UK bloke , can you visit Keihan on my behalf, and thump the counter, and ask if they could get the bloody jig correct , please !!
it's not right , or they're not playing enough attention.
i reckon the bottom elbow or mounting bracket on the left tailpipe is way out.
and unfortunately, i don't have Keith's skills and talent , but i'm good with a little help from me friends.
The standard Keihan system was under a 'bit' of preload and stress (not good), when i headed off to Phillip Island.
it got me back home with the help of a bit of fencing wire, and JD at Pipemasters spent a few hours to get it just right.

Thanks, i would appreciate it.
reckon it's a good system ,, but doesn't fit good enough.
cheers,  Mark
 
Bought my pipes here, I haven't tried them for fit yet as I don't have a bike as such but the photo on the site shows them fitted to a 1976 3CL and Gordon at Feked said in an email to me "The chap that fitted them did not say anything about modifying them in any way, so I must assume that they fitted OK."

Just noted the "big bore" requirement - these are 35mm id
 
Ralph has been on ebay for decades

he must have fat fingers as well as a fungus face
sorry Ralph you just became the four "F"s

Bought my set og stainless downpipes and collector from Gijs Van Dik in Holland. Needed some bending on a propper machine, and then fit jsut fine. (sfc1000). Nice and solid made.
If interested, just give him a call, as he is busy for emails usually. Very helpfull and fair price.

Cheers,
Jacques.
