this kit is the non-res race
I've heard the non-res standard kit and it's almost too quiet
adding the resonator would make the kit sound like stock
Thermal is a great kit, always will be for a 3" kit with no drone. My current set up with the whoosh V2 catless and this non-resonated race kit is the best sound to ever come from my orange car. Sound clip is posted on my facebook page
I've installed a Milltek, Cobra, and Thermal in the past few weeks. Have to say the Cobra gets my vote for best fit and finish
The Milltek and Thermal both fit well with no issues. I just prefer flanges to bolt exhaust together vs the slip fit of the Milltek and sleeve clamps of the Thermal.
Milltek wins for options as they have the race or standard muffler, with or without resonator, and 4 tip styles
polished, true titanium, cerakote black, and carbon fiber
