Rear or side exhaust?

I have a 71 with older side exhaust. It is showing some age and I am looking to replace sooner versus later. This is a driver, not a show car, so I am not concerned about the purist look. I know it is all preference, but I am sitting on the fence on either rear or side exhaust. I am open to opinions.

Thank you!

Joe

Re: Rear or side exhaust?

Just my preference, mainly looks, I like turn downs out back.

I have considered turn downs exiting the muffler but think that would kick up too much debris and be too noisy on the interior. I do like how it changes the exterior tone though (more rumbly).

BTW - nice looking car

Re: Rear or side exhaust?

to me non OEM side exhaust that just dumps out in front of the rear tire just looks cheap and tacky

Re: Rear or side exhaust?

Out the back with '69 model year chrome tips.

Some things to consider:

Exhaust openings out the side, such as in front of the tires generally will make interior noise louder. The Wife might not like that, eh?

Down turned exhaust tips will generally make exterior sound louder (since the sound waves bounce off the pavement). The five-o might not like that, eh?

Any exhaust exiting under the car generally leads to interior exhaust odors. The odors become worse if your A/F Ratio is incorrect. The Wife might not like that, eh?

Any exhaust exiting under the car generally will make interior noise louder. The Wife, eh?

Re: Rear or side exhaust?

My preference is that both exit right behind the rear tires, with a slight turndown.

Re: Rear or side exhaust?

Im definately an out the back exhaust person but am not a big fan of the factory exhaust tips. One other thing about installing an exhaust system. The only thing I welded on my exhaust is the polished tips to the tailpipes. The rest I just clamped together with various clamps and it has saved me several times as I have had to remove the system a couple times for other maintenance. If the whole system had been welded I would have been screwed.

Re: Rear or side exhaust?

Something to maybe keep in mind. Your states inspection???. In my State your configuration could be grounds for failure. Not sure where your from or your states guidelines.

Thanks Keith, my thoughts exactly. I did not want to make an offensive comment.

I had a FULL 2 1/2in system made up for the 70. Even on cars with 2 1/2in pipe behind the manifolds, the OEM tail pipes are only 2in. But on our 70, EVERYTHING to the end of the tail pipes is 2 1/2in. I went with generic Turbo mufflers also.
I debated on going with the 70 style SS oval chrome tips or having the ends turned down. It's a personal choice. Since our 70 is a Malibu and not a real SS, I went with the tips turned down.
In the first picture, you can BARELY see the tips.

Thanks all! Re: current exhaust- I bought her just as is. I believe she was a track burner prior. You provided much for me to chew on. Appreciate the responses!
