Exhaust project

[jensenracing77]

I got my exhaust from Waldon’s today. http://www.waldronexhaust.com/ I am VERY pleased with there customer service. I may run into issues with one of the tail pipes fitting because i don’t know if they had the exact print for the 62 but i had them make me what they thought would be ok. I have a friend that has an exhaust shop so he can tweak it if need be. My biggest problem will be exhaust hangers. What is on my car is not original and i don’t know how the original was mounted. Does anyone have a picture of how the muffler was mounted? Also got a set of Jim’s reproduction tips. They look great!

Wow that looks fantastic. Have you set it next to the factory exhaust and done a comparison? How close is it to stock?

My car had the exhaust replaced and what they put on is not even remotely close to original. I am not sure how close my new parts are to original but should be close. they have all the prints for the 63 Jetfire that shows a resonator. They eliminated that for my 62. They said these tail pipes should fit but i may have to cut the end to length. I can’t remember who, but someone in my other thread said i may have to modify one tail pipe because it is a little differant than the 63. Waldrons had notes from another original 62 tail pipe so i may not have any issue at all. I will post pics along the way but may be a couple weeks till i can start on it.

I will also report back to them so they can know how it all fit. This system was only $365 shipped but i am only one state away from them. Shipping is the killer.

They can also make the crossover pipe and the down pipe from the turbo.

Hi Eric,
The Jetfire exhaust system is covered in the 63 Service Manual. If you don’t have one, you NEED one. The hangers and locations are true to fit.

Thanks Jim. I have the 61 and 62 f-85 books but none of the 63. I will keep my eye open for a copy.

I got the car on the lift today and cut off the old exhaust. Here are a couple pictures of what was on it. I was test fitting many of the new parts and the early signs are that the new exhaust will fit perfectly. I hope to get some clamps and some sort of hangers tomorrow. I have the passenger side hanger for the muffler but not the driver side. Then i have the passenger side tail pipe hanger but not the driver side. I will have to see if i can make something work.

Jim, If i understand the drawing correctly it has no hangers till it gets the the muffler. Is that correct? I see no place to put one before the muffler.

Yes Eric, you are correct. The first exhaust system hanger that attaches to the body/frame is the inlet to the muffler. That hanger attaches to the sheet metal floor pan. The second hanger is on the left side exit from the muffler and attaches to the frame member. Then the two tail pipes are also attached to the right and left frame members with 90 degree drop brackets. The one shown in your pic on the right side looks to be an original tail pipe hanger.

Does anyone have an original muffler I could get measurements from? I would like to get the length of the muffler itself (without the little pipes) and then the length of the pipe out each side. I am starting to suspect that my muffler may be just a little to long. I think i am going to have to get my exhaust buddy to help me out on this. I suck at exhaust. (or should that be blow at exhaust)

I have a GM muffler, part number 380173, made for the Jetfire.

Length of muffler without pipes is 25 7/8 inches.

Single end pipe extends 1 1/4 inch from end of muffler

Dual end pipes both extend 2 1/4 from end of muffler
