Bit of an update.
Had the intake cam repalced due to it causing excess and uneven wear on the cam follower. We found it already had a B cam in it.
Also had a new exhaust fitted. Previously had a 2.75 milltek all the way, now have a 3" APR RSC full system, currently with a sports cat, but that might go soon!
This exhaust sounds very different than the milltek, similar at WOT, but low revs it sounds much more straight through and gives some subtle popping and occasional bang.
Very quite on motorway driving which is nice, as I currently have the rear seats removed.
I much prefer the tips on these rather than the old milltek, and they are easier to clean!
