Bought a set of oval Delkevic exhausts for my XtX about aa month ago. As soon as I put them on they were way too loud with the baffles in. I've ran them for a couple of hundred miles but they're too noisy. I did email Delkevic to ask whether they had any other baffles for less noise but they never responded to any of my emails.

I've now took them off and I'm using the standard pipes again. Anyone else found them overly loud?
