Woudl i be right in thinking that 99% of the time a cat-back system has a straight through centre section.
Would i also be right in thinking that powerflows systems are made from SS, and that SS does not rust.
My m8 when to AB Motorsport in Leamingtoon a few months back and had a full cat-back powerflow system fitted, cost him £300. He rang up tp ask about them making it louder and they said somethign about removing an expansion chamber, so he got me to have a look at it. As far as i can tell wihtout touching it as it was bloody hot, the system is beginning to rust and hence is not SS, and looking at it it looks like they havent even touched the centre section, also the back box is rusting around the bracket mounting point and around the welds to the tail pipe.
Does he have a case for complaining?
