When you guys talk about resonators, are they the short swelled area of pipe just ahead of the factory mufflers? If so, is it possible my previous early build 2010 SS didn't have these resonators from the factory?
The reason I ask is on that car I put JBA catless mid pipes on it with a SCTx3 tune to turn off the rear O2 sensors and the car sounded wicked, even with completely stock mufflers. I just did the exact same thing on a 2013 SS, the only difference being I used an SCTx4 tuner instead. Both tuners out of the box with no custom loaded tune. The 2013 is much quieter than my 2010 was, and also has way less crackle and decel pop. Still has some, but way less than my 2010 did.
I noticed the 13 has resonators ahead of the mufflers and can't honestly say I recall seeing them on my 2010. It's the only thing I can think of that would make the 13 quieter than the 10. Both cars were bone stock M6's.
