Im not one to modify my exhaust (anymore) and I cannot stand loud exhaust. However when I saw this thread yesterday I was intrigued. Looked over what everyone was saying, sent an email to Delkevic and found out they are 6 miles from my house. They said they were open, shot down there, got the 18inch CF, installed them in 40 mins. I'm no expert but this was straightforward and easy. Tiny bit louder but i'm not too worried about it. If needed they said they do have even quieter baffles. May do that in the future but extremely happy.
