sounds like bull***t to me. He wants to sell you another exhaust.Originally Posted by Sabooo
Replacing the resonator with a straight through pipe IS an aftermarket part.
Resonators are ONLY to get rid of drone because of the length of the exhaust, they don't really make it "louder" or softer.. that's the muffler's job.
They have nothing to do with emissions, other than noise emissions. After markets system may or may not have resonators.
Your state is probably just using OBD to inspect cars after 1996 anyway, so if it passes the computer check, then it passes.
The only thing I could find at
is that the exhaust cannot be modified to be louder than the standards set in noise section.
