Does a cat back exhaust sound better?

Does a cat back exhaust sound better?

There are different classifications of exhaust systems, named for how far they extend up to the front of your vehicle. While most OEM exhaust systems incorporate a resonator that further cancels noise missed by the main muffler, cat-back systems eliminate this part to improve flow, performance, and sound.

How much HP does a Borla cat Back exhaust add?

Borla exhaust systems are designed to have the optimal diameters and low restriction flow that promote scavenging. The Borla R&D team performs dynamometer testing on new parts to ensure power gains. We frequently see gains in the 8 to 12 horsepower range, sometimes much higher.

How much torque does a cat back exhaust add?

The new exhaust adds two pound-feet of torque and 2.5 horsepower, but only once VTEC kicks in and the engine needs more airflow. That’s not a ton, but it’s something. It also adds lightness, because the 34 pound difference is considerable.

Does a Catback exhaust add horsepower?

How much horsepower is gained depends highly on the design of your factory exhaust system and the quality of the catalytic converters in front of it. If the stock cat’s can flow a large amount of exhaust gas with creating too much restriction, then a cat back exhaust system should offer a nice increase in power.

Does a cat back exhaust need a tune?

Cat-back exhaust systems affect the region of exhaust after the catalytic converters. They may let more sound flow through, but CB systems do not affect the aspiration of the engine. As a result, Cat-Back exhaust systems do not require an updated tune.

Is cat back louder than straight pipe?

Straight Pipe Vs Catback Straight piping removes the muffler and resonator from the exhaust system. Cat-back exhaust replaces your stock muffler with one that’s less restrictive. This means the sound from combustion will still be suppressed, but not so much – resulting in a more aggressive and louder sound.
