1970 300 exhaust question

[Fireguyfire]

The exhaust on my 1970 300 convertible was redone at some point in its life, and they left the straight tailpipes long, past the rear of the car quite a bit which imo looks goofy.
Can anyone fill me in on what the factory correct way to “end” the exhaust tips would have been on a 70 300 convertible? Would the tops have turned down?

I'm of the opinion that the tips circled in red should be "baloney cut".

This is my car after much study of right vs. wrong. I also had straight pipes from the PO, and had a shop make it proper.

Another good example:

This is a good one, too.

But please understand that the turned down tips should be just barely visible behind the valence panel. What you don't want to do is get carried away and it looks like these two pics of the same car:

Excellent, thanks for the info and the photos. Done correctly tge exhaust looks waaay more appropriate than the straight pipes on my car now.

Yeah, straight pipes just look crazy. That subtle downturn and baloney cut is what you think of at the back of a 440 cop car.

Also, you're not the first person here with this question. It's been discussed before, with lots pics, but I can't point you towards the threads. Here's another pic that I captured from one of those threads. Nice, huh?

Can you buy tips with that cut that I could cut and clamp on?

I can recall such tips at auto stores. But these days it's likely they'll be chromed...maybe not. I just dunno. A muffler shop can make them up so easily and do the tweaks to make them perfect regardless of how your straight pipes are currently arranged. They'll cut back to where they can get a good "run" for the kick up and the downturn/baloney cut. I've noticed that straight pipes are typically the result of lazy work, in that the straight shot doesn't hang close to the trunk floor, thus you have no room for the kick up and downturn behind the valence. The shop would probably remove about 20-30 inches of your existing pipes and the new pieces would be bent to hang closer to the trunk, then kick and turn down. Just guesstimates on my part based on my own situation.

Here's what was on my car. Awful. What was the second owner thinking in 1998 when he had this done?

Chopped off to make room for the new, proper tips:

Factory correct outlets for Mopar are turned up prior to the rear bumper followed by a roughly 45 degree downturn. As previously stated, most good exhaust shops with a bender can re-create this outlet. And that goes for single or dual exhaust outlets. i've seen the same bend on slant-6 A-bodies all the way up to big-block B- and C-bodies

In that downward bend before the upper bend CAN also be a small pinhole for accumulated moisture to drip out of. Just as there should be one in the rear of the muffler's case, just a bit in front of the rear circular seam. I noticed that on our '66 Chrysler CL42 when it was "just a used car" and still under the 5/50 warranty.

Enjoy!

Any pics of your current pipes?

Where do you guys have your exhaust hangers placed ?

Leaving the Hurst aside, none of the tailpipes shown so far is really exactly factory correct (the turn down is but not the very tip) except maybe the RAGTP300 from New York. I will show a photo later of what the factory release ones actually looked like on the end for a Chrysler at least. I worked in Highland Park's Chrysler central engineering center in 1970 and thought the tail pipe end was kind of creative and showed attention to detail.

Here is the correct original tailpipe on my New Yorker with 440HP engine. It is more of a scalloped cutout that ends before it gets all the way to the top of the pipe. It is not so easy to replicate.
