Hello! Since so many experts are busy here and I didn’t get really satisfactory results via the search function, I ask the question here: Does it really bring something, if I would change the rear silencer with my CTR? A better sound would be certain to achieve with it, only it does something like that? The manufacturers specify the greatest values, e.g. performance increase of 5% with Sebring ESD! Or does it only make sense to replace the complete system? Which ESD, or which system would you recommend to me? Should of course also be eligible, or with ABE. Does anyone of you even have a system or an ESD that he would sell? Hope for your help!
