JONNYBOY,I have installed the Supersprint cat back today.Looks great,sounds great at idle but due to the sound proofing not as loud as I would like.Perhaps there is an improvement in performance but I can't honestly tell.It doesn't "drone" but I would recommend getting the twin cats from Lambros in Australia,I can help organise it for you and he is a really decent person to deal with.That is where you will find the difference.The Supersprint system looks much better etc,but you need both,and if I had a choice of one of them it would be the twin cats every time,they are amazing.The cats improve both sound and above all performance(13KW and at least 15% more torque(well that is what I estimate as the torque wasn't tested but the power was.
