Picked this up a couple of weeks ago...
First things first it needed an exhaust so 5 days later I bought a DC Sports cats back system.
For some reason reviews on DC exhaust were bad as people said it drones and has horrendous rasp around 2500-3k rpm so company discontinued it and prices dropped. So took a gamble as I had an e46 M3 which is just rasp everywhere and turns out DC exhaust isn't actually that loud, no drone at all and absolutely zero rasp and it is very good quality and pretty cheap. Only slight problem was a couple bolts could have been 10mm longer to make fitting easier and bolts supplied were made of chocolate so a couple stripped just normally tightening but DC exhaust was a good buy....decats to come I think.
