MDifficult said: Cheers Ben - I know it would be amazing but it basically means very few chances to go on track. From what I understand.. no aftermarket V10 exhaust passes regular track noise limits. Yes, you can test in the paddock with the valves closed but if you run on track with them closed the additional back-pressure kills the engine. I'd be limited to anything that's no limits, which isn't much and, lets be honest, is where all the big boys play I think you are looking at this wrong…Put an exhaust on the R8. Then you can buy a light weight more track focussed car for track. More cars,

Okay, hands up, I admit it, I'm pretty sure I'm falling HARD for our little red MINI Cooper. Not only have we done hundreds of miles of fault-free and entertaining driving lessons, and not only does my daughter LOVE it, but I've borrowed it a few times myself now and it's fantastic. Some of my favourite things... 1. The little three-pot 1.5 makes a great little gruff noise, plenty of power and torque (but not too much), with a little turbo lag, making driving a joy2. With the window down, you can hear all sorts of wonderful turbo-spooling and whooshing noises. Yes, it's probably a failing bearing or something but it's so entertaining. 3. The gearbox is a little notchy but.. it has rev-matching on down shifts! First time I've driven a manual with auto-rev matching and while my petrolhead sensibilities were initially offended, it actually makes it so joyous to drive and SO much easier for a learner driver because it smoothes out all that coming-into-a-roundabout-downshifting and allows them to concentrate on the road. 4. Having now done a bunch of jobs on the car, you can see all that grown-up BMW engineering shining through5. It's bloody great fun to drive - especially with the little 'sport mode' engaged (weightier steering and a livelier throttle map).So enamoured am I, that it was time to start treating it to some upgrades. First up was tyres.. it had some absolutely shagged run-flats on the front and some brand new non-run flat Falcons on the rear. I debated replacing the lot for new run flats (as the car doesn't have a spare) but decided to just go for a matching pair of Falcons on the front. A can of tyre weld, AA membership and a much better ride is the right option. Next was the battery. Although the car would start okay, it was a wee bit laboured so I plugged in Bimmerlink and the battery was showing 60%. I stuck it on the Ctek 'regen' mode for a day but that didn't help, so decided to take all the covers off and have a look.. surprisingly it was still on th
