I really (but not intentionally) gave Ken's the chance to prove they mean what they say about customer satisfaction. I bought a perfomance muffler for my Mk1 GTI. It was a tight fit. It took two return visits to eliminate the rubbings and vibrations, and in this case, another smaller muffler - the work done all on their own nickel. I have a nice solution now. They WILL make good on your installation! I will be coming back with my other cars.
