I'd have a word with Charlie at Pro Speed in Cardiff to see what they can offer

Out of the several phone calls to s/s exhaust suppliers I made, he was the only one to listen to what I wanted: single pipe 2 box V8 free flow system with a throaty rasp under acceleration but free from any motorway cruising speed boom. I also wanted the system tucked up and away from the speed bumps that plague my area.
For about the same cost of an off the peg system, he made a custom s/s system on the car to fit my existing tubular manifolds.
It was worth the drive from NW London all the way down to Cardiff and back again, a happy customer.
