Hi All

Wondered if anyone can help shed some light on a set of new TYGA stainless steel exhausts I would like to purchase for my NSR mc28. I know when making this modification the set up should change i.e air fuel spark etc but as these are a like for like part is there any need to adjust anything as the air flow in and air flow out should still be the same? Am I wrong. could somebody please explain?

The NSR is restricted through the PGM 4 card I believe. I don't think its been modified.

Thanks

Ian
