Just joined today (02/21/2022) I really like my stock exhaust on my 2018 Cadillac CTS but the two Billy Boat exhaust systems really sound aggressive. Depending on how loud and aggressive you want you CTS to sound, I would go with either Billy Boat system.
Hands down the Borla touring exhaust.
Nothing else comes close.
ZERO resonance at any cruising speed. Quiet as stock at idle but get on it and it’s a super sports car
I like my 2014 CTS Lux 4wd 3.6 exhausts sound but I’d like it a little louder. But I find it hard to believe that I have yet to find any way to do this for less than $500. Any ideas?
I’m running a Flowmaster setup, and it’s got that classic muscle car tone. Not too obnoxious but definitely turns heads when hit the gas. Great for the price too!
