If you are looking to save a little money but still get most of the benefits of a cat back exhaust system, however, aluminized steel may be the way to go. Made from traditional steel that’s been coated on all sides with aluminum-silicon alloy, these systems are very strong thanks to the metallurgical bond which still provides a level of corrosion resistance. While the aluminum coating reflects heat well, the steel can corrode if the aluminum layer is chipped or scraped off. Most cat-back systems will come in either an aluminized or stainless steel version.
The only difference is that it features straight perforated pipes. The original exhaust systems focus more on just reducing the sound and not shaping it to give it that desired deep growl. One function shared with both the axle-back and the cat-back exhaust systems are shaping your vehicle’s tone.

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.
