I had a 2 1/2" TTI system with stock manifolds on my 440 Cuda...bad drone, especially at cruise 45-55 mph. I put on TTI 1 7/8" headers no other changes and drone went away. Overall car is probably a little louder with headers, but that annoying drone is gone and I can now cruise in comfort and listen to music if I want to.



I didn't want to hear that! I have had it with headers though, 8 hours to re and re twice, had ceramic coating fail both times and gave up....
