Thanks John but the AR pipes already have the 90° bend terminating in neat diffuser tailpipes integral with silencer. The old system came off with relative ease this afternoon and was already offering up an AR pipe on one side as a test fit when the sky turned very black. Slightly uphill for the few yards to garage entrance so bit the bullet and fired up with the cats only! Very loud but maybe not as bad as expected, and just beat the rain
I will probably wait now until the stainless bobbins I have on order from SiFab arrive at end of week.
