When it comes to improving your vehicle’s performance, you have two options. However, stainless still can be very expensive, as opposed to aluminized steel which is very affordable. It is also resistant to corrosion, just not to the level of stainless steel. Since there is no back pressure and the diameter is large enough, the engine will not use a lot of energy to push the exhausts out. While getting a cat-back performance exhaust system can be pricier initially, it can save on a lot of costs in the future. These exhaust pipes are usually wrapped in sound-absorbing materials, mostly fiberglass packing.

Different exhaust systems offer different noise levels and tones, but how? Sound quality and overall loudness of an exhaust system can vary significantly depending on the pipe diameter, size and design of the muffler, resonator inclusion, and the number of outlets. For this reason, all systems sold on RealTruck are filtered by noise level, including loud, moderate, and quiet. From the factory, most manufacturers employ small-diameter piping, restrictive mufflers, and noise-reducing resonators, significantly smothering exhaust flow and sound quality. A front pipe back system replaces a few key components of the OEM Honda or Acura exhaust found on your EX, Touring, Si, or A-Spec that are after the Front Pipe (the pipe that goes under the engine).

Glasspack mufflers do not have extra sound-absorbing material. So, in order to absorb sound, they use the glass layer and packing. But if you are making your order on partcatalog.com, you can always inquire about the recommended tube diameter for your exhaust system by providing your make and model. This can lead to a significant decrease in torque and horsepower as well as rpm.

To maintain catalyst efficiency, the air–fuel ratio must stay close to stoichiometric and not remain rich or lean for too long. All of Milltek’s performance exhaust systems are manufactured from T304L stainless-steel
