View Full Version : Exhaust Questions

I was under the car tonight doing other things and I got to looking at my exhaust. The car came to me with exhaust problems, no tailpipe and a cherry bomb muffler and a leaky manifold. But I didn't realize there was a big hole in the crossover pipe. I discovered that tonight. The hole is there because the pipe and muffler was held on with a coat hanger, so the pipe was not straight and it hung against the crossover pipe, and cut into it.

So, being unable to help myself, I cut the exhaust pipe down and took it off. I was thinking about doing a dual exhaust to begin with, but now with the pipe off I'm very tempted to just do it. I think I'd like to do it myself, it doesn't look real hard. But i don't know a lot about doing it. So I have a couple questions.

Is it remotely possible that if I had a pipe bent to the same shape that's on it now, it will fit and run along the driver's side of the car too? There's already bends in the frame where it's supposed to run. I'd love to be able to just have two pipes bent to the same shape as the one on there and have them fit. Also, will the pipes that go over the rear axles fit both sides?

If I do do duals, are there fittings that I can buy to match up to the manifolds? Where the manifold mates to the exhaust pipe the manifold is rounded out like a ball, and the exhaust pipe end is a bowl shape. I assume you can get fittings to match that?

What's the purpose of the x or h pipes that you can get with a dual exhaust kit?

Finally, anyone know of any kits that will fit a 73 lesabre? I was looking on Jegs but they don't have a kit for a B body. There's one for a century, how close is that underbody to mine?

Also, the chasis manual shows a muffler and a resonator. Do I need to put both these on there?

no you do not need the resonator.
i had a friend who owned a chevelle that came from the factory with mufflers & resonators. he replaced the mufflers with a piece of exhaust pipe and kept the resonators. that car was quite loud.
on my 70 chevelle, i removed the tailpipe & resonators about a week after i got the car and installed a pair of drop pipes.

Tom, as long as your transmission crossmember has clearance on both sides for duals, go for it. Unfortunately there aren't any kits available.

Before you try to do it yourself piece by piece with ten thousand trips to the muffler shop, just save yourself a lot of grief and drive it to one of the many muffler shops in your area and have it all done for you while you wait. There are shops that will be glad to help you out, especially as you look towards Ypsilanti.

There's a guy on ebay that sells exhaust kits for any buick through 74. I might buy it from him. $320 shipped.

Post a link if you would before you pull the trigger. There are some attempts at "universal" kits out there that don't fit well at all.

Call a few shops to get a quote over the phone, too.

I don't think it's a universal kit, he said he builds them to fit the car.

I agree with trying the local shops first also.
Here in Milwaukee the muffler shops are running deals for true duals from the manifolds back for well under 300.
The muffler guys at the smaller shops still take pride in the work the do and I was allowed to watch everything I had them do for me. I told them nice and tucked, etc,,, and he did it no problem. I even threw the guy a 20 for doing a great job.

Good luck on whatever you decide.

if you don't have access to a lift, or have never done exhaust work before, bring it to a pro.

I have bought from this Guy and Waldron's Exhaust, klassics was okay fit,one bend wrong but I could fix it. I've tried to convert an a body TA kit to a Centurion, not good especially over rear axle. Waldron has great service, product. :o

You realize that because everyone says I shouldn't do it, I'm going to do it.
