[ribeye998]

I'm thinking about buying some second hand termi silencers for my 2003 998. Will I need to replace the ECU or make any other changes if I replace my standard silencers with a pair of 45mm termis? Also do they pass a trackday noise test or would I have to replace with the originals on those occasions I venture on to the track?

Just to confirm that yes you will have to change the ECU if you fit the Termis, we had to replace the link pipe on ours as well. I think that you will find that the correct Termis for a 998bip are 50mm - I can check ours if you want.

Our bike is borderline for Brands Hatch, but decibel eaters sort that out.

If you want to get the best, performancewise out of the bike from fitting termis then you will need to do something, reflashed ECU, powercommander, I'm not sure if there is an official ECU option for termis for a 998 BIP.

I made a few mods to my 998 without and change of ECU, did away with the intake mesh, cams dialled etc then had the Air fuel ratios (AFRs) checked on a dyno, they came out as economically lean , so no need to do anything unless unless I wanted the last few BHP/lb ft of torque.

The noise limit at the trackdays you want to do will determine if the bike is too lound with termis.

You should be OK at any 105db day, my 998 is well under that with 50mm termis.

Any noise limit under 105db could be a problem depending if/how they test the bike.

Various tracks have different limits, check with the organisers of the days you are thinking of.

Thanks for your help - where can I get the new ECU ? are they generally available from a Ducati dealer or only from a more specialist supplier?

You can have your current ECU reprogrammed, far cheaper than buying New
Or if you want to keep your original as is then you can get a reprogrammed used unit
Antony or ChrisW can do it for you
As could I if I had the spare time
