Guess at what I found..., ... at the local Autozone Options

Ok, so a buddy of mine (who doesn't know much about cars) has told me about people who put mufflers on tuners that aren't actually designed for them. So, as curious as I am, I went on Youtube to see if what he was talking about is true. Sure enough, there's plenty of "backyard Hillbillys" that do random s*** to there domestic cavaliers and ghetto looking escorts. But, beyond the appearance of all of them, they sound pretty decent. So, as RiCeY as I was feeling today, I went to the local Autozone and bought one of these...





I know what you guys are saying, I'm a complete ricer.

But you guys can't deny it, Cherry Bombs FTMFW!

Congratulations, you just bought cutting-edge technology from the 1950s.

It's a glasspack. It's obsolete in materials and construction.

You see all those louvers inside? They stick into the exhaust flow, with the idea that they direct the exhaust gases into the fibreglass where the vibrations are absorbed. Slight problem: turbulence is bad. You want to get the exhaust gas out of the engine as quickly as possible, not force it to bounce off a hundred little obstacles and then into itself.

Furthermore, the insulation on those things is fibreglass. These glass strands eventually break down and blow out, leaving you with an echo chamber -- and a turbulence-inducing echo chamber at that.

Modern versions of this ancient straight-through muffler use a perforated pipe without the louvers, and wrap the interior pipe with ceramic mesh backed by stainless steel wool. Such straight-through mufflers, which are often mistaken for resonators by the uninformed, provide volume control with minimal impairment of the exhaust flow.

The simple fact is, there's very few pieces of exhaust equipment you couldn't manage to strap onto the underside of your car. The thing to consider is whether or not they'd be of any benefit. If you put that piece onto your exhaust in place of a straight pipe or even the stock resonator, it will reduce your car's ability to exhaust burnt fuel. You could use it in place of the stock muffler, which is a baffle design, but while you'd slightly improve flow, you'd end up with a truly obnoxious car.
