Default Muffler on a 1959 TBird

Spring has sprung in Portland and the ThunderChicken is out of the garage, washed, tuned and ready summer; with one noisy exception.

Both mufflers are shot!

Everything on the car is stock so I'm wondering; is there any value in spending the extra $$ and buying a set a Flowmaster or should I just buy a stock pair from BirdsNest or Larry?

I'd rather not do any exhaust modifications so I am wondering what model of Flowmaster would make for an easy install.

Thanks in advance for your answers.

The first time I replaced the aftermarket mufflers on my '60, I used Larry's "stock" replacements. These are okay, but very large. I had to position these on an angle and still half the muffler showed itself prominently.

When my shop replaced the entire exhaust, I asked for Walker regular chambered (quiet) mufflers. These are smaller than the stock, cost about 60% of the stock, and sound the same to me.

Believe me when I say these produce a decent classic sound. I drilled a tiny hole at the lowest point to allow water to exit.

personal opinion is just delete the mufflers althoghter. depending on if you want it quiet or not of course. I run true dual straights dumped at a angle before the rear tire on both sides. like the race cars. I love it. no drone at all on freeway but roars when i want it to. oh and hearing a big block idle is just great

I wanted a louder exhaust when I was young. It always turned out pretty annoying. The truth is noise is tiring. Everyone has different tastes, and I find my Thunderbird with a stock exhaust is louder than my Challanger RT Plus Classic.

Thumbs up

I installed Summit Racing Turbo mufflers on my '60 430cid car. They sound tame

Good job. I've heard mufflers "break-in". I always thought that was a stretch, but my Walkers definitely sound louder after a few hundred miles-and I quite certain it's all going out the tail pipes. Everything is buttoned up and welded.

Flowmaster's don't sound very good with them out toward the end of the system where they would end up on a squarebird. They also tend to drone really bad, personally I'd avoid them.

My 65 had a great tone to it, but it had some of the longest glasspacks installed under it that I've ever seen. They were put on in the 70s, found the invoice for them in the center console of the car.

I couldn't agree less...I installed 2.25 staggered Flowmasters out back, and there is no drone at all, sounds just hotrod enough but not loud. Mind you I did the whole floor in dynamat when I replaced the carpet so that didn't hurt. But I like the sound of flowmasters!

It really depends on a few factors.

1. which flowmaster muffler you get (ex. 40 series, or 50, or 10) lower the number the louder it is.

2. if they are Delta flow. supposed to cut down on drone.

3. where they are dumped. (under the car or out the back
