The caveat being that you don't live in a state or province that requires a test as to the performance of the exhaust system. Here in Canada its BC and Ontario. Throughout the US, it varies. I'm sure you know what is required for your area.
Even here in Manitoba, though no testing is required, it is illegal to tamper with or modify anything in the emission control system...
