Ok, My Calmini exhaust is all rusted out and I need a repalcement. I want stainless steel so I don't have to replace the exhaust every year. Should I go with a premade exhaust like Borla, and Gibbson or should I look at a custom job. I got a name of a good place that uses Flowmaster and Magnaflow systems.
