Why would tips be omitted in CA? Noise? Pollution? I always saw them as more decorative than anything else...



Same principle as a megaphone < the tips enlarge the tail pipe ends. The end tips have a lot to do with how an exhaust sounds, just look at sport car mufflers and ricer fart pipes. I know that my ’68 RR had Dodge rectangular tips on it and I knew that only the ’68 Hemi RR got the tips so for both reasons (wrong tips and not an option on the 383) I took them off and put the turned down tail pipes on it and it got too quiet for me and lost that nice “trumpet” sound. I’m putting the chrome tips back on even though they are not correct for a ’68 383 Road Runner because they sound so nice!
