RantMachine Posted July 3, 2017 Share Posted July 3, 2017 A certain plonker has purchased a set of downpipes (Arrow) for his bike (Z1000SX) that end in the same diameter as his silencers (Scorpion) start. Misleading information on t' web is to blame, I'm told. Any suggestions for a good bodge before a local exhaust fabricator laughs all the way to the bank? My favourite idea so far involves a saw, a bit of steel tube, and a couple of exhaust gaskets and clamps. Perhaps not appropiate for a bike that costs twice as much as both mine put together Quote Link to comment Share on other sites More sharing options...
Westbeef Posted July 3, 2017 Share Posted July 3, 2017 Should the tubes fit inside each other or are they meant to be coupled? Quote Link to comment Share on other sites More sharing options...

Westbeef Posted July 3, 2017 Share Posted July 3, 2017 Is the difference quite large or minimal? If it's pretty close you might be able to get them in by taking some off with some wet & dry. Quote Link to comment Share on other sites More sharing options...
RantMachine Posted July 3, 2017 Author Share Posted July 3, 2017 The difference is the thickness of the pipe Quote Link to comment Share on other sites More sharing options...
JRH Posted July 3, 2017 Share Posted July 3, 2017 stuff a solid bar up the silencer inlet and roll it round the pipe with force and "swage" the pipe out. this should / may enlarge the entrance enough to force the down pipes in. if you can get it big enough cut a slot in the silences pipe and us an exhaust clamp and exhaust putty to finish off.Done this loads of times years ago on car exhausts, but they were generally mild steel not stainless.

RantMachine Posted July 3, 2017 Author Share Posted July 3, 2017 Nice, I'll suggest both options tonight and see if he likes the sound of either. Depends on the quote from the fabricator, I imagine Quote Link to comment Share on other sites More sharing options...
JRH Posted July 3, 2017 Share Posted July 3, 2017 Fabricated will look better. Quote Link to comment Share on other sites More sharing options...
Westbeef Posted July 3, 2017 Share Posted July 3, 2017 I seee, what's stopping him just clamping the two ends together with something to seal them without chopping them up, the mounting point for the silencer? Quote Link to comment Share on other sites More sharing options...
RantMachine Posted July 3, 2017 Author Share Posted July 3, 2017 That was my initial thought, but it puts too much distance between them and the silencers end up at a funny angle, stops the panniers mounting. Either needs some overlap or a bit less length in the mix! Quote Link to comment Share on other sites More sharing options...

JRH Posted July 3, 2017 Share Posted July 3, 2017 [mention]RantMachine[/mention] might need to trim the pipes though on reading your last post. Quote Link to comment Share on other sites More sharing options...

RantMachine Posted July 3, 2017 Author Share Posted July 3, 2017 Ooh, that's a cool gizmo. I'll forward that on too. Quote Link to comment Share on other sites More sharing options...
fastbob Posted July 3, 2017 Share Posted July 3, 2017 Some car exhaust fitters have a machine that bends and swages pipe. I'd probably swage the cheapest bit just in case. This place has such a machine.http://i.imgur.com/wgblTOB.png Quote Link to comment Share on other sites More sharing options...
