Hi, I've read lots of previous posts on fitting a ypiece replacement for the catalytic converter and am 99% sure i'm going to get a remus y piece from motorworks. Just before i do.....are there anydownsides to this I should be aware of? I understand i don't have to alter any mapping and that it should reduce vibrations, sound a bit more throaty and and help pick up on mid range. I read on one posting though that the cat actually creates a certain ammount of back pressure that is required for maximum power. Is that all tosh? does fuel economy drop much?

I will be keeping the standard cans on my 1100ss. The rest of the bike is standard although i have considered the K&N option but fear this will require some form of remapping. again, any thoughts?

thanks chaps

Just do it mate, there isn't any downsides.

It'll sound better even with standard cans. There isn't any need to modify the fuelling on the bike, providing you don't change end cans, or increase inflow. When I changed mine I did notice the power was spread differently. However it was keener to rev.

Backfires but that adds to the comic value of a sporty Bemmer.
Enjoy!

I fitted a remus y piece from motorworks last weekend. Its a very straightforward job make sure you have a 22mm spanner for the 02 sensor, and read the instructions posted on the site.

I've kept the standard cans the exhaust note is a bit deeper sounds nicer. Mid range seems stronger and the bike seems to run a bit smoother. Fuel consumption seems about he same.

Go for it
