Borla currently offers 2 Raptor aftermarket exhausts: 1. ATAK - their loudest, most "aggressive sound" https://www.borla.com/products/f150_raptor_xpipe_wmid_pipes_part__60638.html 2. S-Type - is not as loud as their ATAK (pronounced "attack") system https://www.borla.com/products/f150_raptor_xpipe_wmid_pipes_part__60637.html The 3rd one is coming soon - it's the Borla Touring Exhaust which will put out less aggressive sound than their S-Type Exhaust but it's expected to be more aggressively tuned than the Ford Performance exhaust which is designed by Ford and made by Borla to their specifications. Note that this Borla Touring exhaust is not the same as the Ford Performance Touring exhaust...
