Overview:

Flowmaster's race-oriented Outlaw® Extreme Cat-back system is designed for the enthusiast looking for the maximum sound level and performance from their 1986-2004 Mustang GT, LX and Cobra models with either a 4.6L or 5.0L engine. The turn-down tailpipes drop at the rear of the transmission and eliminates full length tailpipes to maximize the sound level and allow for extra clearance for wide tires and modified suspensions. This mandrel-bent system is designed to mount behind the factory catalytic converters, or most factory style aftermarket H-pipes. The Outlaw Extreme system delivers a super aggressive interior and exterior tone and is suited to the enthusiast who wants the most aggressive components they can purchase. Like all Flowmaster® systems, the benefits include improved throttle response and power. Designed for an easy fit, these systems include all necessary parts and hardware for easy installation. Note: Ideal for off-road racing use.

    Poor fit, filter compartment won't close completely.
    Mitsubishi Outlander SE 2017 (not sport). However, the filter doesn't fit properly. The edges on the bottom are too thick and don't compress to fit. I was able to force it to close, but it was way too tight. Original has thinner edges. FRAM filter from Walmart worked great. I'll go back to those after this one.

    Excellent quality filters for your car
    Size: CRV (2023-2025) 2.0L Hybrid
    Greetings fellow countrymen, the two filters I purchased were an exact fit for my 2024 Honda Accord Touring non turbo. This vehicle is well known for the odors generated from the manufacturing materials used. The quality, the structure of the engine air filter is outstanding, and an exact fit. The cabin filter without a doubt, is much better than the OEM Honda filter. Both filters are top quality, manufactured to strict standards and fit perfect, no more toxic assembly smells of glues, battery cell, misc plastics and bonding agents. In conclusion, Outstanding performance, highly recommended. Respectfully submitted, master tech 4
