I just got the Borla S-Type axle-back. Send a PM to ApexChase on this site - awesome vendor he will answer all your questions honestly.
Love mine. It's the way an SS/RS V8 should sound. Nice rumble/tone, no drone and you can still one another talk inside the cabin. The ATAK was too loud for my daily driver it's the type that "will wake the neighbors"..
Good Luck..
