As a result, the glass pack mufflers end up producing sounds that are more aggressive and louder than the straight-through muffler. This is a little bit different from most original exhaust systems. Today we’ll focus on the cat-back exhaust systems and what makes them stand out. There are the header-back, turbo-back, axle-back and cat-back systems.

This qualifies as one of the STRANGEST stock exhaust parts I have seen. For some reason Toyota/Lexus decided to weld a straight section of 60mm pipe to the cat outlet flange, angle cut it, weld a 50mm pipe pipe that has its last couple of inches expanded to 60mm and match angle cut. Also note the O2 placement is in the 50mm sections of the Y pipe where the sensor tip takes up a good portion of the available flow area.

But with so many options available, it's easy to get lost in the world of aftermarket exhaust systems. While some companies may try to lure customers with an attractive price tag or flashy branding, it's quality of performance, sound, and construction that truly sets a great brand like Invidia apart from the rest.

Cat back exhaust systems come with exhaust pipes, muffler and exhaust tips, so you have everything you need to replace the exhaust. The cat back is the section of the exhaust that runs from the outlet of the catalytic converter to the exhaust tips. Exhaust systems that include this often feature a large pipe running from the converter to the muffler, with mandrel-bent turns and glasspacks for reduced back pressure. Your go-to spot for information on the exhaust system, as well as mufflers, catalytic converters, pipes and sensors.

In layman’s terms, a catback exhaust system provides a smoother, more streamlined path for exhaust gases to exit your car, allowing your engine to work more efficiently. When catalytic converters were first introduced, most vehicles used carburetors that provided a relatively rich air-fuel ratio. Oxygen (O2) levels in the exhaust stream were therefore generally insufficient for the catalytic reaction to occur efficiently.
