Just bought an 07 S4Rs. It has a Trermi system already installed with the updated ecu and air filter. The thing is I would like to get rid of the cat and I was wondering if I installed the midpipe (979A00103) would I have to upgrade to a different ecu or could I have the existing one remapped?

You will probably have a "check engine" light issue if the midpipe eliminates the O2 sensor....John

If you have the DP ECU you do not need the o2 sensor. I installed this and left the o2 sensor in anyway. Worked perfect.

Thanks for the link. The midpipe available through Monster parts looks good and its alot chaper than the Ducati performance one.

Let us know how they work out if you pull the trigger. Its not a full 52mm system which would require either a new full-termi ecu or a PC. An inexpensive way to eliminate the udder to clean the look ups.

Also ask what type of material, steel or SS. If they're steel expect to spend time cleaning off the rust.
