Hot Rods Yesteryear's exhaust tone ?

Damn it! The bobber went down.

 

Looks like a 1970's ad. Is it?

 

Y-block engines with straight pipes to the rear bumper make the best music

 

Looking for the video!

 

Yea, but that **** sure got a lot of looks hangin off my duster!!!
Actually they were the first generation of race mufflers, when NHRA was freaking out figuring all the race tracks were going to have mandatory muffler laws. They were long 3.5" gl***packs, they weren't bad at part throttle, but at WOT, they were not much different than open headers. I loved 'em! Pretty much all the local street racer types used them, they came out around '75 or '76, and were available till the mid eighties. They weren't advertised, and to quote Thrush, "not intended for street use". We sold a ton of them at Dix.

 

Not sure when they first came out, but my guess is around 1970/1971, give or take a year based on my memory of the chain of events surrounding my experience.

 

Cool ad. Looked to that era.

 

I was going to replace the exhaust system of my Caddy 390 this winter, eliminate the mufflers and resonators and go with some long Brockman Mellowtone steel packs just before the tailpipes. They are made to order. Just did some researching here on HAMB, and people seem to like them, so I figure I would try them too.

 

No offense but could you type into the computer, I can't hear you. Sounds like you got hosed by what you thought were great mufflers.

Really galls me to hear an old school looking custom, that sounds like a late model Mustang! X pipes, H pipes, Flowmasters, have no place on a Custom! My preference is Brockmans, but Porters, or a set of original Smitty's (like on my 55 Olds) have the right sound for the era.

 

Hello,

In 1961, we had the stock mufflers taken off of our 1958 Chevy 348/280 hp Impala and added in a set of tubular straight pipe mufflers from a truck parts store. We got the set of mufflers from our friend’s gas station garage in Los Angeles, along with a set of Corvette tube mufflers. The sound without the extended tail pipes out below the rear bumper was outstanding. It was similar to open headers, but a little softer. They did not boom when letting off after a race. Did I mention that it sounded great in the back alley of our local drive in restaurant in Long Beach? Accelerating down that quiet alley sounded like a night at Lions.

But, a neighbor who was a LB policeman just happen to mentioned that my 58 Impala was bordering on illegal and that I would get a fix it ticket soon if I did not make it quieter. So later on, the local muffler shop installed the rest of the tail pipes and that made it much quieter. The motor still idled with a rump/rump sound, so it was good.

But, the straight pipe mufflers were much louder than the stock ones, even after we had the stock tailpipes installed. They also improved our times at Lions when we raced and it was still considered “stock” for the A/Stock cl***. No need to unbolt the cut outs under the car.

The idea was no restrictions in exiting the exhaust. All muffler pipes were the same size and since these straight through mufflers did not have those awful stock muffler’s crazy baffles and re-direction of the exhaust it made the car have more horsepower. The sound was smooth, deep, and loud.

 

My 56 BelAir 2 door post car has a warmed over 327, fender well headers, "H" pipe, Flowmaster 40'2 and pipes exiting out the rear has the best sounding exhaust. I believe the "H" pipe is what makes it sound so great. Back in the day I also had a black 58 Impala 280 HP which was a 348 with 3 two barrels and three on the tree. Heard a Corvette with great sounding pipes, asked the owner what mufflers he had. He said they were Jimmy truck mufflers. Installed a pair with the pipes exiting just forward of the rear wheels they really sounded great.

Hey G,
Like minds/rides...etc, etc. I cannot remember the name of our truck mufflers, but in those days, we were happy to get anything for free. The sound was perfect, straight through and little to no baffles. Actually, my dad probably bought those from his friend and told him to give it to us for the Impala. Nice to have automotive/connected friends.
Thanks,
Jnaki

 

i used to run gl*** packs from montgomery-ward. about $5 a pop. annoyingly loud under the seat without tailpipes, and would reach a certain pitch that was like someone drilling in your head. added tailpipes and they were sweet! '53 ford v8 and '61 impala 283.

 

Sounds like your hearing thing's. I'll spell it out . The muffler's have been under the car for nearly ten year's with only turn down's. They sounded great and many thought my SBC was a BBC .

 

Thanks for the quote johnny

The best sound I can remember is the sound from the 60's Corvette's Side pipes. They used "Chambered" Mufflers so that's what I put on my car. They sound just like the 60's deep rumble. I also placed "Echo Cans" at the end of the pipes. At idle, it sounds like a Big Block coming from an Inline 6! There are plenty of folks on the HAMB that have heard it.

 

RapRap, true about chambered exhaust. My car a idle reminds me of a Camaro.
