Larry, they went to a place in Shotts, North Lanarkshire, called Complete Auto Solutions. They had been recommended by a few other folk that they both know. This was the first time the company had fitted them to Mk 3.5s so asked them to leave the cars with them for a few hours. Lifetime guarantee too.
Both Donald and Iain are really happy with the service they received as well as the exhausts
The company say they'll do mine at same price if I ever want it done. But I now know of 2 Mazda back boxes going spare for my car, so in no rush
