If you own one of these and are fitting anything other than an exhaust end-can you are completely wasting your money. Full systems may save a bit of weight, but they won’t do much else. You certainly won’t end up with any more power…
And this is the trait of the EURO 4 spec motorcycle. In this instance we were able to make the bike feel smoother with the PC5, and getting rid of the lambda and SAI interference helped it but in truth you could spend a bundle and end up with nothing to show for it. In fact, fit something a bit mass-market to a bike like the BMW S1000XR and you’ll lose power.
In truth leave well alone, or fit an end-can at best…
