The welds are decent quality but prepare for cutting, adjusting and re-welding, it won't be a straight bolt on. It doesn't sit right through the subframe and they have taken into account the quattro so it fouls the chassis on an LCR. Also as Dan says you need a flange on the back of the decat for LCR

I have this, I would say it is still worth getting if you are handy with a welder or know someone. I had a sports cat welded into it before I installed it.
