Have you considered dumping them right after the muffler?
I've noticed a lot of people trying to bend their way over and around things back there where you can just dump them right after the muffler. You'll also save time and money if you run it that way. In addition, I think that Camaro's look better without exhaust tips in the rear. The back end of that design is so clean that you really don't need them. What do you think?

I has a 1967 with a 396, long tubes and the exhaust dumped right ahead of the 3rd member. Sounded amazing around town, especially when I romped on it. Didn't sound so great at highway speeds, the drone came right up through the floor. As a young man, I loved the sound wherever I drove it, but nobody else did. And now that I'm older (and wiser?!?) I don't think that I'd dump the exhaust like that, just to make drive ability on the highway more tolerable.

Here are pics of mine showing custom tailpipe routing around the G-link and stock width Ricks tank that is not dog eared.

You didn't mention a muffler...Did you mean dumped after the third member with a muffler? If this is true, I had no idea that the extra 3 feet after the muffler (aprox) made such a significant difference in sound even say with like a Flowmaster Super 44, but you make a good point since the exhaust is dumped right around the rear end. I'm 33 and I don't want a super loud exhaust. The car is flashy as it is and I don't want it overly loud exhaust. Figuring out the right sound is gonna be a nightmare for me ugh...getting a headache just thinking about it.

This is how I ran my exhaust. Very simple. I have had to remove it several times and this setup is easy to put on and take off.

The photo that TheJDMan posted is very similar to the exhaust set up that I used.

I wouldn't say that the exhaust was particularly loud, the turbo style mufflers and exhaust were 2-1/2" and the sound wasn't obnoxious or excessively loud for the average hot rod of the day. I owned the car from 1988 to 1997, and I never had a noise complaint. And after driving cars with 3" exhausts and cars with glasspacks noise level could have been much worse, but it wasn't loud for this particular car/exhaust set up.

What I really would have done different is route the exhaust to the tail of the car, as it keeps the sound from the getting "trapped" in the third-member tunnel, because the tunnel acted like an echo chamber. The sound/pressure pulses exited the exhaust, reflected off the pavement then up into the tunnel, and the noise came up through the back seat. When the engine varies in RPM it wasn't noticeable, but at freeway speeds and constant RPM, the low frequency tone, often called the "droning" sound, would just rumble from the floor pan up into the cabin.

Most of the time it didn't bother me, it was a hot rod, the sound of the car is part of the driving experience. For me personally, the only time I noticed it in a negative way was after a long/hard day of work driving in the afternoon, the noise fatigue would be more noticeable because of my mental and physical fatigue. The kids in the car seats, my wife, etc. didn't have the same driving experience that they had in other cars (from a noise perspective), they were much less tolerant of the drone across the board.

And I know that drone can be experienced with the exhaust exiting the rear of the car too, part of it is the muffler design.

If you plan to use it for long hauls, I think it is a consideration. Getting the exhaust to the rear of the car will reduce the drone as it will take some of the noise and move it to the rear of the car, eliminating the noise from under the car.
