DNA MOTORING CBE-IS300-NRT Stainless Steel Cat Back Exhaust System [Compatible with 01-05 IS300 Altezza XE10]

Why Upgrade Your IS300 Exhaust?

Factory exhaust = quiet, restrictive, and forgettable.

This system upgrades your car by:

• Improving exhaust flow
• Enhancing sound and tone
• Slightly increasing horsepower and response

Translation: your IS300 finally wakes up.

Upgrading vehicle’s exhaust system is a great way to build horsepower, free up trapped torque, and improve upon restrictive factory systems. The larger pipes, low-restriction mufflers, and tuned resonators of a well-designed performance exhaust system can make a world of difference on your vehicle. The net result is lower auto exhaust backpressure, more horsepower, more torque, and a much better sound.
