Haven't updated this in while. Mrs turned full chav and wanted rid of the stainless Monza so that was sold and a new exhaust was purchased. 20mm spacers are back on as we had a problem with them so the car looked like it was driving round on 4 space savers for a while until Eibach sorted the issue out. Just fitted new front splitter too and had its 2nd service at 18k and needed the front brakes replacing after 20k. Also gave it a machine polish to get rid of most of the swirls from its winter abuse.
New exhaust again, sounds great. No drone, can't hear it on the motorway or at similar speeds but under full throttle it sounds fantastic, some of the cracks and bangs it knocks out are great.
Front splitter from an Australian company.
