Finally I got the mufflers today and have just finished fitting them and just came back from taking it for a test drive up the road.
Its nice as its not droning down low and just a nice soft note. When you boot it sounds weird,(may need time to get used to it) probably sounds better outside of the car though.
The only thing that shocked me when I opened the box was how big the tips were, I didnt think they were that big, so I hope it doesnt make me look like a knob. Apart from that pretty easy as these were the easiest mufflers I have ever had to replace.
