Remus and Y-piece

Chewie2112 · May 25, 2015

Ok, just throwing this out there.....

Just been told that it can damage your engine to run a Remus (or any aftermarket can) and a Y-Piece de-cat pipe without an ECU or power commander upgrade.

is this true?

was who ever told you this trying to sell you an ecu or power commander?!

Chewie2112 · May 25, 2015

Funnily enough, the guy who told me was told this by a BMW garage, who persuaded him to fork out for the PC!

No, 36k with Remus and Y-piece. I bought/fitted them when the bike was new and the BMW dealer said no upgrades to the ECU/fuelling were required. They also confirmed the warrenty, back then, would not be effected in anyway.

Well, I think you have your answer!

If you search back far enough in this section you'll find reference to burnt out valves and engines running lean and a warning around the use of Y-pieces and race cans. I'm guessing that's where your advice has come from. As per above, lots of people have fitted y-pieces and race cans and not had any problems but, funds permitting, getting a remap or installing a PC would certainly add further benefit and make the bike nicer to ride. Good luck :thumby:

My 1100 has done over 100,000 miles with a Remus and y-piece and I've never touched the engine - still goes great guns :thumby:

I have done over 50,000 miles with a Remus and Y. The OE parts were fitted once a year for the Austrian test during the time I lived there, otherwise they live in the boxes they came in when I collected the bike new from the dealers.

+1 Remus (baffle in) and Y, no cat with no problems (42k)

Have just fitted free flow filters (removed air box completely) but I've done this in conjunction with remap (still leaving baffles in remus for now).

How much difference do you think there is between the last 1150 and first 1200 engines?
