Was gonna say, I've never seen a stainless traditional Flowmaster, only the newer ones like the FX. But all the chambered ones I've seen rot out after a few years. I had a set of 40s on my first Mustang that one of the baffles let loose. That car is why I DESPISE flowmasters, so much drone

Ivr heard good things about purple hornies. Theyre very similar to cherry bomb. I actually have one on my 4.3 s10.

The normal chambered type are available in stainless as well.

When I quoted that post, I tried to be as nice as possible. What I really wanted to say was "You can't just say you have Flowmaster mufflers and love them for whatever reason, and just leave it at that". There's way too many kinds." But I didn't want to sound like an a$$, lol.

I have a set of Flowmaster 50 series big block mufflers on my truck in 3". They came on the truck, which had been sitting in the guys back yard since AT LEAST 2006. They have zero rust and still look mostly brand new. All the 3" exhaust pipe that was running in and out of the mufflers was almost completely eaten through with rust before I replaced it all. They are actually fairly quiet, but have a nice deep rumble.


I would suggest looking at the Pypes mufflers. They are ~$100 and full stainless. I put one on my Suburban right before the flowmaster to tone it down a bit more and it really deepened the rumble and took the slight amount of drone that I was having under full load while towing right out.

I used resonators from Lyell’s Stainless Exhaust in Ontario for the mufflers for the sidepipes I made for the 76. They are basically glasspack mufflers. They sound like glass packs.

However they also make and sell chambered type mufflers of various configurations, might be worth checking out. Stainless and made in Canada, eh.

Which Flowmasters?

There's 10 or 15 variations (or more maybe... I didn't go count) of Flowmaster mufflers with different tones, volumes and also different materials of construction.
They didn't have that many options back then, but I just looked at what they are selling now and what I had seems to now be be the FlowFX series mufflers. Sorry for the slow response.

Those ones are actually one of the newer offerings. The ones I've heard (not many, honestly) sounded similar to the typical Magnaflow design.

Yeah it was similar to Magnaflow in sound. Although what I had wasn't called FlowFX it was designed and built like the FlowFX series they are selling now. It had the same straight through design encased in stainless steel like the FX series. I remember looking into one end of the muffler and seeing daylight out the other end. There was a slight S turn in the middle of the muffler that left approximately 1/3 of the passage through the muffler unobstructed.

I’ve had the same Flowmaster 40 series on my 77 for 20+ years. Zero issues and sound great. Small block 350 true duals out the back

With that said, I run black widow on the dually and love the sound of them on that, too. Big block 454 true duals with an H pipe

Just my 2 cents. I like to try different mufflers on different rigs just to experiment. That’s really the only way you’ll find what you like for your truck.

I do the same. I try to run a different setup or muffler style on all my cars and trucks. I've got quite a few, but none sound the same. I've got a few favorites, but every time, I experiment with something different than what I already have just to see if I may like it better.

Ive got 2 long turbo 18"-20"mufflers 18"-20" dual exhaust, IIRC they are Summits TM. They werent expensive fancy name brand. They have been on my truck for at least 30 years with Doug Thorley tri-Y- headers. I installed & welded the alumi coated pipes myself. All are still in excellent condition.
