Mufflers? we don't need no Stinking Mufflers! My T when we first fired it up. I have since put a short "header collector insert" in to take the edge off the sound. but it sounds like the hot rod it is.
@Bob Lowry Hello, Wow, someone else also found these straight through, but quiet mufflers. As pictured, they are loud and sound as if there are no mufflers. But, after testing with short chrome tips, then exit before the rear wheel side spots on the 58 Impala, and even over the hump with exits after the tire opening caused great sounds, but not for daily driving. The mufflers by themselves never got a chance at the local dragstrip. There would have been plenty of “challenging the rules” protests, if we were to run in the stock eliminator classes with these straight through mufflers. They were appropriate as they were in the factory parts catalog and parts departments of Chevrolet dealers. But, if the loud mufflers were the only ones racing during eliminations, protests would have been filed, instantly. After the installation, it was perfectly legal to run them in the A/Stock class eliminations all day and night. Two short down exhaust outlets were installed. Then, the bevy of installations of the Corvette tubular mufflers and tips. Since our friend from Los Angeles liked that we were involved in trying to make the 58 Impala go fast and faster, yet still keeping it stock, he offered us a pair of straight through Corvette Mufflers. Our dad opened his trunk one day and there they were. We instantly took the Impala to our friend's muffler shop a few blocks away. The longer the muffler exhaust tubes were in place, the less sound came out. But, the short tips only, the side exits and even over the hump and out of the rear tire area, the sound was horrendous with no available normal conversation possible. Although, the full acceleration down the Cherry Avenue Drags location reminded me of the actual Lion’s Dragstrip races and time trials. It was the blasting sound and full power of the Impala that was so much fun. While all of the changes were going on, our local muffler guy was creating the custom fit longer pipes from the tubular mufflers to the hump, over and under neath the rear bumper. That was the nicest sound of the idling motor, the acceleration and acceptable entry into the quiet, almost enclosed driveway and parking in the “left” side of the garage late at night, ok. It was virtually impossible to "quietly" drive into the garage and move the Impala in and out to get it to the left side of the garage two space parking slot. Our dad's big Buick sedans were always parked on the right side. He was pretty good at parking after he got home from work. But, in order to have two cars in the narrow 40's garage, we put a hanging windshield string and plastic ball on the end, so when he came home, he would put the plastic ball right in front of his driving/park position. That way, there was always space for our Impala to actually squeeze in and out with having to move the Buick out of the way. Jnaki Although we cruised around with the mufflers by themselves, the side outlet before the rear tires, and a short over the hump exit behind the rear wheel opening. all three spots were loud. They brought smoke and fumes inside of the open windows and not the nicest arena for driving around with friends. For the length of time it took the muffler guy to finish our custom pipes, we had a blast cruising around and accelerating. But had to find the rpm’s to quiet down the exhaust noise when approaching a black and white car ahead. Note: Recently, a neighbor had sold his M3 and bought a new mustang, for what reason, it will confuse everyone, including me. His old car was a classic. His new one farted every time he let off of the gas pedal. When he fired up early in the morning, the whole neighborhood could hear his new car and added Magnaflow mufflers. Then he backed up and went to the nearest stop sign and then anyone that did not hear the first fire up, now heard the pop-pop-pop sound as he came to a halt at the red stop sign. When he accelerated down the street, the noise shattered the quiet community and the instant we heard the pop-pop-pop sound, we knew he let off of the gas and stepped on his brake going downhill. He moved away and now the early morning sounds are natural wind and the coyote families out for a stroll with the newborn pups. Much better than those Magnaflow pop-pop-pop mufflers. YRMV
