So, in summing up, 'Y' piece plus standard can the way to go ?

[Kenny]

I'm new to these modern bikes
I have a 2004 single spark R1150R and have given her a jolly good servicing ( hate the
servo brakes though ). All sorted except silencer set-up etc. Currently has the standard silencer on and an unknown 'Y' but this set-up pops and farts occasionally on the over run etc but runs lovely. Now before I take it off and re-fit with exhaust paste etc...do they all pop and fart anyway as a matter of course ?
I have a new OE CAT so could easily go back to the set up as the R1150R left the factory, standard everything.........just need a few pointers before I operate on the beast over the weekend ( I haven't got a stubby etc )...did a search and lot's of variations from the good old days came up
Just asking like

OEM headers + a Stubby (available on eBay) is the way forward. Ran my 1150 like that for seven years; no issues.

Did the Standard cat and silencer, y piece and Remus can and y piece and standard can thing on my r1150gs, best compromise is the y piece and standard can and yes they all pop and fart on , a lot more than the standard set up and a lot less than the Y piece and race can

After running 1150GSs for 18 yrs I've tried everything and settled on using the CAT with a stubby.

Great sound with no popping at all, more grunt and no silencer to clean etc. etc. etc.

nother vote for cat and stubby.



and when you feel the weight of the silencer you will know why

Re fitted cat. Just as sweet and no popping.

With John the Greek's bespoke performance chip - about a hundred snoojits or less - and by losing the 15kg weight of the OEM catalysator in favour of the Y-piece, using the standard end-can, you'll have the most noticeable increase in mid-range power, a tiny increase in fuel consumption but more reliable and smoother running all across the rev range that you could wish for, with no overrun unburnt fuel-popping at all.

Even with the untouched OEM chip inside the ECU, the combination of the y-piece and the standard end-can is an improvement in grunt, albeit with a certain amount of unburnt fuel passing through into the hot end-can, causing the popping that some people object to on the overrun. Doesn't bother me on my Rockster though.
AL in s.e. Spain

Thanks guys, all replies appreciated; probably going to re-fit the CAT and sell on the ( genuine Remus ) Y piece...should get about £120
