I have a set of genuine 750SS exhaust cans. Thought they would fit my bike (had high hopes!). It would appear the 2 into 1 system fitted is a home made job. Phuck I say! Option would be to take the bike on a trailer to an exhaust shop and see if they can fit it. The header bolts are rusty, they dont look real good which brings the issue of them snapping if I locate an exhaust sytem. Any ideas?

SORRY, RE POSTED IN THE SPORT 750 SECTION

Oh, being a USA import the headers are smaller diameter than the rest of the world. So, finding a set in Aus wont fit... I can see why the bloke was keem to sell

If I had a choice I would def go for the bigger ones . I used to know a guy who ran a Ducati workshop and raced belt drive 2 valvers and he swore that the 1st thing to do was upsize the header dia and re-jet
Im understanding that the 2 into 1 is a bit naff . Do you have to fit some tested or certified exhaust to get the bike road legal or are you just looking to go back to original ?
Do you have a Mig welder ........its not that hard to make your own headers out of exhaust bends .
If the rusty studs you mention are the ones in the head it would pay to get them sorted before they break . Give them a good wire brush up and see just how rusty they really are . If none of the pitting is deeper than the bottom of the threads you may be ok ......but .....some peeps loose sleep over things like that.....not me

How sure are you about that Pete ? (Im not ) The flange is the same size and apart from that they are just slightly bigger dia . I would have thought that the biggest issue is that you would have to modify the ends to suit the rest of the system .
906 and 750 have different length stroke so the heads are further apart and the headers are not interchangeable .

Hey Mc tool, yep the road worthy needs a standard pipe. They take photos of it and send it to Vicroads Also vicroads want to inspect it to see if it needs a specific engineering certificate for Victoria its been done in QLD but.... PITA really. I'll get the bike back together and take it and the standard exhaust to a exhaust shop, they will be able to make it fit. When I get a RWC and club plates Ill think about a 2 into 2. Have to get it made.

This is what I have. Part number 57310221A
This slips into the header pipe. The header has an external dimension of 45mm

I have a fairly basic mocrometer and I'm reading 38mm I reckon if I go bigger they wont fit onto the cylinder head. I'm gonna jump the fence an see if the Paso lads know if their headers are 38mm. A paso system should fit
