I'd like to modify my 2009 MazdaSpeed 3 stock exhaust but I'm going to be moving to VA next year and I don't want to do something that will prevent me from passing inspection. I was wondering if some of the VA guys could give me advice as to how much I can do with my exhaust and still pass inspection. I'd like to replace the stock DP and leave the stock CBE. As of right now the only mods I have are a RMM and SRI.
Thanks in advance!
