I have changed my central silencer for a bigger one since it was under warranty but the original one I noticed more strongly than now with this larger one I would have to put it the same as the original
on the exhaust pipe of my Seat Ibiza GTI 8valvulas engine AGG I put the specific of the car and after 4 months it broke sounded like sand and sheet metal then as it was in warranty they fixed me but not for the specific of the car since it is totally different a bigger belly I mean the central muffler of the exhaust pipe after the catalytic converter and from there like the Ibiza lost low
