Speaking of the resonators, my 71 440 Six Pack Charger does not have them and looks to have the original tips on the tailpipes too. What's the deal on the resonators and tips?is this also an early VS late production situation?

I don't think any 71b 440 equiped cars ever came with resonators.

Here is an illustration that might help. Even though the illustration shows that the 440 applications had tailpipes not resonators we have had customers claim that their original 71 6barrel/pak 440 cars were equipped with them. Like always "never say never with Mopar". Maybe for some extra cash one could get resonators as no modifications are required for installation.

Could it have been 'required noise reduction' like in 1970 for CA sold cars?

I'm not 100% sure as I don't really follow post 71 cars much( yea I know I should )

But I looked at a 71 Hemi runner years ago, and I'm almost positive it had resonators in ft of the chrome tips. Maybe it was factory and maybe they were added

From the 70-71 Factory Parts Book. Jan 72 revision.

w/440 Eng. 70 - 3404802
w/440 Eng. 71 - 3466994 & 3466995




It would be nice if someone had an earlier version of the parts book which could confirm what the conclusion is, that earlier up to Jan 71 it was an H pipe with only one part number then to the two part numbers mentioned above.




FSM from March 1971 has the same numbers as above

"He is wrong"
"He doesn't know what he is talking about"
"I have never seen a car like that so none were ever made"
"Until you show me proof I will not believe you"


This is all Bull, there were so many variations back then and unless you pulled the parts and assembled the car yourself, you only have an assumption

ABSOLUTELY! I had a FIRESTORM on a Duster/A body brake post elsewhere on this forum. It boggles my mind when people step over one another with such little decorum. If I make an incorrect statement, I shouldn't expect to be reprimanded. If I see something that I think may be wrong, I try to let the members know that previous posts may be wrong, then offer my perspective. I know that I have much more to learn. These cars ARE wierd. Do the GM and Ford guys have these kinds of problems or is it just us?

To further substantiate the original factory installation of H-pipes on 1971 440 B-bodies, my brother's 9/70 Ontario built 4-speed 4-Bbl GTX was so equipped. I know this because it has been in the family since it was purchased new.

On 440+6 cars (71 B), the only way you got resonators was if it was coded for exhaust tips (N42) and noise reduction (N97)
Hemi cars came standard with resonators and tips

My 71 440 V code has individual head pipes. They have the flattened areas and clearance dents, and I am 99% certain they are the originals. The build sheet shows left and right part numbers.
Very late build date.

(2) 71 GTX's, both original H-pipes still intact. I've sold one already, but still have the other. So yes, 71 440 cars had H-pipes. Maybe some didn't. Would be interesting see some others. There is a 71 GTX 10k mile V-code car thats fairly well known, Autumn Bronze Metallic, and another one, Hemi orange & yellow V-code, done by Roger Gibson (was in Wellborn Collection), that was a concourse cars.
