Best addition I have ever did. When I added the Cat Back exhaust I did get some drone at any steady rpm above 3,000 rpm. When I added the test pipes it is now quieter than the stock exhaust at cruising speed. No exhaust sound unless you down shift and get on the throttle. At idle it is much louder (sounds great) and when accelerating it sounds awesome. A must have for any modified exhaust. Now for smog no problems here in California. In my city they do not use the sniffer test, just the OBD11 test. Passed with no problem.
