Thought I'd share my latest experience with you all. I bought and fitted (myself, 4 hours on my back) a Cybox exhaust, I only bought the 'cat back' bits as I've read from various places the de-cat makes it too noisy.
As far as fitting goes I had issues with all 3 hanger brackets, breaking out the blow torch on one bit to bend the bracket to make it fit. I wasnt impressed by this. The tailpipe sits slightly off centre coming out of the rear skirt, I am going to try to rectify this soon ( ive brought my range of hammers out of retirement just for this.
My biggest disappointment is the noise, its too loud! the one thing I didnt want and the reason I didnt 'de-cat' was the noise..... yet its really loud.
To end on a good point, I will say the quality is very good and have not been disappointed by this in any way.
