However, we have had customers call and order h-pipes for their 71 440 powered cars claiming that they wanted to replace the original h-pipe that was still on the vehicle. Parts manuals list a right and left headpipe only for these 440 cars so if anyone shows a parts manual that lists an h-pipe we would like to see it. Like the old saying goes "never say never with Mopar".

There was a change over later in the year where the factory started to use seperate headpipes. I owned a '71 U-code GTX that still had it's original H-pipe with the factory flattened areas. It had a SPD of Dec 17th 1970. A few other members have survivor cars that still have the OEM H-pipes. We compared our Broadcast sheets and the cars with H-pipes listed this in the front pipe boxes: EXHAUST LT RT 00 01 The cars equipped with regular headpipes had: EXHAUST LT RT 93 76 '70 Super Bee 440 6 pack 4-spd 4.10 Dana N96 EB5 ‘70 Super Bee 440 6 pack 4-spd 3.54 Dana FC7 ‘70 ‘Cuda 440+6bbl 4-spd 3.54 Dana N96 EB5 V1W

So it appears according to the book no H pipes. When you say during the year there was a change, do you mean it started as an H pipe and then went to two separate pipes. Because in my book for the 1970 b bodies it list only one part number 3404802.

"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 based on a BS or FT.... Granted there are some really knowledgeable people here on Moparts that have accumulated many years of pictures and documentations and have seen and examined many cars out there, they have findings that are worthy but not 100% accurate, really, unless they were there back then, bets are all off..... I will give you an example: I bought a 71 GTX from the original owner, he ordered the X and waited for it to be delivered. He has owned it all this time until I purchased it. When I purchased it we spent time talking about the car and and the history of what he did with it and the problems he had with it. He even kept the original factory installed tires and rims he removed when he installed the slotted mags on the X back in 71. When I bought the car he surprised me be putting them back on the car for me. Well the X is a 4sp so the carb listed for it should be 4967S, well it isn't, it is a 4968S, this is an Auto carb. I have been called an idiot and I do not know what I am talking about by a so called expert here on Moparts, he said no way that carb was installed on your car, show me the documentation that it was installed..... Bullsh-it, to you and to all that think that way..... I better stop and turn the rant off, step off the soapbox and have a cup of coffee.. 71 GTX 4sp Dana GY9 HD Road King

Up to about 2 years ago when a 71 440 "B" body exhaust system was ordered we automatically sent the customer an h-pipe exhaust system thinking that this was correct. Then we got straightened out by a few 71 "B" experts in the field concerning what was correct regarding the exhaust. We had no way to prove otherwise by either documentation or by reviewing existing survivor cars. So now we automatically send (2) headpipes unless a customer opts for an optional h-pipe for 71 440 applications. So far this has made most people happy and has kept us out of hot water with the experts. Either way put what you want on the car because most people would'nt know the difference. 6006789-Y-OneAd-AccurateLogo.jpg (88 downloads)

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. 6007362-71TpipeandTipIllustration.jpg (108 downloads)

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

Maybe it was factory and maybe they were added

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?

The build sheet shows left and right part numbers. Very late build date. Last edited by demon; 04/19/21 09:43 AM.

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.
