04 RT replaced muffler - popping on deceleration - not convinced I did a good job

[colesyboy]

R1150rt 2004 - rotten old muffler change - as its integrated into the cat, that had to go also - so no cat anymore, so all a bit lighter, but still a fat old machine. Bought a dominator muffler https://dominator.pl/en_GB/p/R1150RT-Exhaust-Silencer-ROUND/536

I had to clip off the oxygen sensor on the rotten old exhaust as it was welded to it with rust. I'll get a new sensor in good time, but after taking it out for a spin I get lots of farty popping when decelerating. Feels also a bit more sluggish in accelerating.

Does the removed cat & sensor have any bearing on this? Aside from the fact that I might have done a crappy job on replacing the exhaust? I used the exhaust putty and cant feel any air escaping from the joins...

help!

My '98 R1100GS has no cat and a Remus can... pops and bangs a bit on the overrun. I'm happy with the fit of the exhaust, so I think it could be a case of 'they all do that sir'

It needs the O2 sensor to work correctly but still may pop after that is fitted with removing the cat.

After you have the O2 sensor back in place, have a read of this thread https://www.ukgser.com/forums/showthread.php/503427-Steptoe-cat-code-plug
