Got this on at the weekend, although the cars filthy, so didn't bother taking pics.
Sounds nice, deep burble on idle, but not overly loud. Only noticably louder then stock from 3.5k rpm upwards. Most importantly, theres no drone that can be heard through the cabin.
As a DIY job, providing you have a proper lift or a pit, it really wasn't that difficult.
I struggled for about 2-3 hours using jacks and axle stands before admitting defeat, that I couldn't get the height to drop the front of the centre section to feed it over the rear beam.
Took it over to the pit at my uncles, and was a 20 minute job!
Thanks again Damian!
