All are capable of delivering a race-inspired exhaust note along with more power and torque. And this is why cat-back exhaust systems are considered to be one of the best performance modifications that are rewarding in power and sound and are highly effective for all driving purposes. Aside from maximizing your sound gains, the RSC® technology in every CORSA high-performance exhaust allows for a completely free-flowing air path to optimize your performance with every drive.
Namely, it replaces the rear axle-back and tips and then a portion of what we refer to as the mid-pipes. This system is emissions friendly and doesn’t require any tuning.

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.
It is important to note, however, that going too large may cause a dip in performance when gases pile up and exit the system slower resulting in torque, rpm, and horsepower loss. After the emissions are channeled out from the cylinders by the exhaust manifold, they are deposited into different catalytic converters.

A catback exhaust system is a type of aftermarket exhaust system that replaces the muffler and tailpipe of a vehicle. It is called a "catback" system because it starts at the catalytic converter, which is located in the middle of the...
The cat back system’s pipes have a larger diameter than a standard set. So, your vehicle will get to perform better at a fraction of the work it outputs. An
