My Milltek is highly recommended chap. Mine is cat-back system with 4-motion style twin pipes out the back and the 4-motion style valance. The valance only costs about £40 and most places that do the exhaust will sort one out for u if u want some steel poking out the rear. The sound is nice gentle rumble not that loud at all in the car, esp when u lightly using your right foot! But when u sink your foot to the floor it sounds awesome, not a cheap boy-racer style rasp or anything, a nice deep growl, very nice!! Milltek is made from aircraft grade steel and comes with life time warranty so peace of mind assured, happy cruising!
