    The cold air intake arrived fast and was extremely well packaged to prevent damage. The quality is outstanding—sturdy materials and a perfect fit for my car. Installation was simple with clear instructions, and I noticed an immediate improvement in performance and throttle response. The seller communicated promptly and was very professional throughout. Highly recommend this seller for anyone seeking quality auto parts!

    Sounds very good

    I replaced the original Walker SoundFX on '02 Avalanche (5.3L) and I am pleased by the sound of the Flowmaster. It's not necessarily loud, actually very quite until 2k RPM then it becomes noticeable but not too much. Has the typical Flowmaster's rumble from the outside but doesn't scream excessively. When compared to my other vehicle - Tahoe with Magnaflow - I have to say, this one sounds bit more distinctive. Very happy with it. The length is exact match to factory muffler, yet the body is slimmer and clears the frame better. Sound comparison: youtu.be/2d0oRsqkMSQ
