I used Howell Racing mufflers as they make a great performance muflfer that is 4 inch round outside and 3 1/2 inches inside and the right length for a Cobra. Now if you like them a bit louder like me, turn them around backwards. Running a all aluminum 496 FE 681HP and it sounds and runs great........
