69 Dart/Barracuda 340/383 tail pipe question. Are Part numbers 2925671 and 2926670
2 inches or 2 1/4 inches?
2 inches or 2 1/4 inches?
Here pictorially is what is being described. These are stock 69 340 factory tailpipes.Been through this on my '68 cuda 383. Different venders supplied slightly different variations from the factory. So there will be some debate about what was "original". Originally my car came with 1 7/8"/ 2" exhaust w/ tips. The system was 2" through the mufflers and over the rear end. Then the pipe was reduced to 1 7/8" out to the 1 7/8" tips.Accurate Exhaust was very helpful as they have collected NOS pipes from these cars and reproduce them. Along with exact reproductions they also offer variations of the system. For me, I decided on 1- piece headpipes and 2 1/4" system out to the tips. This makes it the same as a "B" body exhaust system. The system fit very well and the car has a very healthy sound, and looks original.
the Accurate Liimited tailpipes are 2 1/4 unless you ask for something else.
IMHO if you want something smaller it would be more straight forward to just stuff a rag up the tailpipe
The tips are 1-3/4 ID so the swell must be 2", I didn't measure that but I will when I get back to the shop in a couple of days...so if the end of those pipes are 1 3/4 ID where they are swelled for the tips, I can only guess how small the actual tailpipe before the swell is - 1 5/8 or less???
Well I took a close look at my NOS pipes today, they are 1-7/8" OD and 1-3/4" ID. They do not have slots where the tips go in, so I don't know what the pipes are above. I bought these pipes in the late 80's and they had the part number on them that matched the 1969 Mopar parts catalog. The last pic is the reducer I had to use to make them work with the mufflers Accurate sent me. There has never been exhaust through these pipes, they were on my 69 383 GTS that burned in my garage, that is why they look bad. The tips and pipe hangars are NOS also...
