When I bought my '70 Road Runner, it had a really bad exhaust system on it consisting of headers and some homemade tailpipes with very small mufflers and the factory tips welded on. The car was very loud and there were many exhaust leaks from broken welds and cracked headers. The last time I drove the car before doing this work, the left muffler broke off. I didn't think the car could get louder but it did and I wasn't able to drive it any further.
I ordered a new 2 1/2" mandrel bent system from Tube Technologies (TTi) Exhaust with Walker Dynomax Super Turbo mufflers. I also bought stainless steel reproduction exhaust tips. They don't look exactly like the originals but will look good on the car.
My friend Scott came over and helped me work on the car. It didn't take much time to remove the old exhaust system from the car since we weren't concerned with saving anything from it. We borrowed my neighbors reciprocating saw and just started hacking the junk off. We had one manifold stud broken off already and another one is not the correct type and may have to be removed. Here is a picture of what came out of the car.
I bought "reproduction" stainless steel exhaust tips for the car to fit the 2 1/2" pipes. I looked at all of the ones available and these seemed to be the best quality. The problem with all of them is that they aren't really the same shape as the factory tips. My factory tips were in bad shape and couldn't be used again. Here are pictures for comparison.
While I was under the car and had the exhaust system out, I decided to take some pictures of the underside. It is all pretty clean. The only problem area is the trunk floor, which I already knew about. Basically the gas tank is holding up what's left of the center of the trunk. I pulled the gas tank out to fix a leak and to replace the bad fuel sender. Click here to see the undercar photos.
