This system has a lifetime guarantee. There is no reason why the dealer should have an issue with it, its a better quality part than the original and you are not removing the cat.
It is a beautiful sounding system. I have sold some with rolled edge tails, some with straight cut tails and just had a request for single exit 100mm round tail, we can do that too.
Has anyone fitted one of these exhaust systems to a 'normal' punto (i.e. not an Abarth) as im sure my bumper doesnt have a cut out/space like the Abarth bumper does?
