Thrush, Cherry Bombs, What? Straight through design with fiberglass batting installed for noise reduction? Very little niose reduction, more exhaust flow, but also more chance of backfire. No backpressure on the exhaust. They will get louder as they age, the fiberglass batting comes loose from the inside of the muffler and eventually you end up with a straight pipe. Very cheap, but usually an obnoxious sounding exhaust, with a lot of popping when you let off of the accelerator.

Glasspacks have been seen a overall performance muffler interior the 50s and early 60s. After that, extra modern mufflers such simply by fact the unique "rapid" muffler (from rapid automobiles) grew to become the overall performance piece from the previous due '60s until the80s. whilst flowmater, borla, and others got here out, the glasspack and rapid kind mufflers have been out of date. Glasspacks are great for a 50s vehicle or a rat rod, and so on, yet have very poor overall performance and sound features whilst in comparison with extra contemporary chambered or absorbive/dissipative designs inclusive of Flowmater or Magnaflow.

Glasspacks were considered a performance muffler in the 50s and early 60s. After that, more modern mufflers such as the original "turbo" muffler (from turbo cars) became the performance piece from the late '60s until the80s. When flowmater, borla, and others came out, the glasspack and turbo style mufflers were obsolete.

by reducing the "back pressure" on the exhaust valves you do get a little more horsepower BUT they themselves do not add horsepower. Your best bet is to accept the fact that glasspacks simply add the "manly" growl to your car and not much more. You want more horsepower? Its a mathematical formula, the valves open for a duration of time and allow a certain amount of air/gass mixture, the cylinders hold x-amount of volume, compressed or not. Change the cam for the most, simple, quick, way to increase horsepower.

You can get some horse power gains,but they're also louder. If it's a muscle car it will make it sound like the General Lee. If it's a four banger it will sound like someone riding a moped with the muffler removed.

I had a guy do the exhaust on my pontiac, and unbeknownst to me they put glasspacks on it. The sound was so loud and obnoxious I returned a week later and had them change to quiet mufflers. Unless your running a hi pref engine, the HP gain isn't worth the noise. C.

Glass packs are awesome on muscle cars! However, I would not put one on our gto. The flowmaster w/ our headers are more appropirate for the style of our car. Extra hp?? Well, probably not enough to make your car feel all that much different.

Mostly for noise and the horsepower increse is extremely minimal!

if your looking for good mufflers and added performance i would look into flowmasters or hookers aero chamber
