Hello everyone am new here, I got a Panda HP and was wondering what would be the best exhaust system for it from the cat back. I was toying with the idea to get one custom made from a local exhaust specialist because 1. I can have it to a certain loudness 2. I was thinking of a Ragazzon Group N ( the exhaust doesn't put me off its just that the only place that seems to sell them are gazella racing and i've been told to stay away ..... if i go custom it would only be a cat-back, am I right saying that the cat- back is pretty much a centre pipe and a back-box?
