So I have been thinking about this for while now and I just wanted to hear an opinion. I have a 2018 Skoda Octavia 1.8TSI 4x4 CJSB (as the title suggests) and I was thinking about emptying the rear mufflers of any insulation that it has and leaving them like that. The only thing that is setting me back is if it's worth it or not, I keep going back and forth about it First, I don't know if it would make a substantial difference or not. Second, I don't know if on a long drive it would become anoying or not. Last but not least, I don't know if it's worth it if I get stopped by the cops since I kinda want it to sound more sporty but at the same time I like flying under the radar I am looking forward to hearing your thoughts! Thanks !
