1976 Trans Am Cold Idle Video..

1976 Trans Am Cold Idle// Video Pontiac Firebird Trans Am 400 4 spd black and gold.. It was a rare day in South Florida an nice chilly 52 degrees out.. At 6 am in the morning it was just a beautiful day and a great day to take the Trans Am Out..

Now I don’t know if it’s just me but there is something about a muscle car when it’s idling in chilly to cold weather. Either it’s the cam or the kind of exhaust you have on it.. Or maybe it’s just quiet all around you and that exhaust crackle just sounds 1000 time more awesome on that day.. But me being from the northeast I really miss that when I am in south florida.. I really do .. Now I love my 1972 Impala but let’s face it the exhaust on that is all stock and original as to the day it left the factory..  Very Quiet and boring but if it ain’t broke don’t fix it..

Not the previous owner had the single outlet removed so the car has true dual exhaust with a crossover. But he added cherry bombs to it I never liked them. But I gotta admit I do like the way this car sounds.. It’s not annoying like all the others I have heard.. I remember back in the day this kids who had Z28s and Trans Ams would cut slits in the resonators to make it sound loud..

Yeaaaa Ummmm No I remember thinking what awesome looking cars.. But man do they sound terrible .. After enough teasing they fixed to exhausts back to the way they should be.. Hey it was the 80s and there were speed parts but not like today headers were awesome but not many cool sounding performance mufflers around.. You had Sears and Mufflex you were actually better off cutting holes in your mufflers lol.. Cherry Bombs were like the hottest things out but as I said I never really liked them..

Below is an ad for the Cherry Bomb Glasspack

A glasspack is a type of automobile muffler in which the exhaust gas passes straight through the center of the muffler. The basic design consists of one smaller tube centered inside of a larger outer tube that is enlarged or swollen in the middle. The gap between the swollen part of the larger outer tube and the smaller diameter center tube is packed full of fiberglass, hence the name.

Glasspacks are an old, simple, and relatively inexpensive muffler design that are effective at reducing back pressure, but not very effective at muffling noise. Glasspack mufflers were originally offered by Cherry Bomb back in 1968.^[1] Since then, the name of Glasspack is closely associated with this brand name, yet today that is not the only company, who produces Glasspack mufflers. The distinctive features of the Glasspack mufflers are traditional red powder coating, original straight-through construction and fiberglass inner tube, and its distinctive classic sound. A longer glasspack will reduce noise to a greater extent than a shorter one. Sound is also dissipated into the fiberglass damping material. Other glasspack mufflers have perforated louvers punched into the center core which can reduce total flow capacity. The turbulence created by the perforated louvers therefore achieves greater muffling capacity at the expense of total volume of air flow. The more turbulence created, the greater the muffling & less total air flow / power production capacity. Depending on the directionality of the louvers, one can choose between slightly higher flow capacity or slightly greater muffling. This lower flow but slightly quieter design approach is commonly used in glasspack mufflers.

Some modern muffler designs are similar in principle to the glasspack, but use more sophisticated sound-absorbing materials such as stainless steel mesh, and more advanced acoustical engineering, reducing noise while retaining the power-preserving advantages of a straight-through exhaust flow.

They still make them to this day, but with all the other choices you have nowadays. I just can’t believe there are so many. In a way it’s kinda wild that they are still in business. I’m not going to lie I would have bought Flowmasters. I use them on all my cars as I stated before when I was a kid I liked Glasspacks but not really now I like a nice throaty sound.
