R61 Performance Exhaust?

If its anything like the countryman, have the 2nd cat and res removed. Way cheaper then any bolton solution. The cheapest bolt on would be a megan cat-back, and even then it still involves some cutting\welding (depends how you want to install it). In reality there is no "bolton" without cutting.

the welds between the dp/flex pipe, flex pipe/2nd cat and 2nd cat/resonator are terrible
i have seen photos of them being as small as 1-7/8 id from the pipe size of 2-1/4 ... mine were right at 2 inch
i installed a milltek dp back system that eliminated everything from the dp back and picked up 5 car lengths over an identical all4 to mine in a 3rd gear rollon from 1500-4500 rpm
if you do not eliminate the restrictions of the oem welds all you will get is noise
