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.

    Comfy and cute
    Size: 3X, Color: Black
    Perfect length. I normally wear a plus size 2X but I wanted it to be looser fitting so I got a 3X and it’s the exact fit I was looking for. The length hides my apron belly. The fabric doesn’t stick to me. Materiel is nice and lightweight. Hasn’t wrinkled, dryer didn’t shrink it, super stretchy. Perfect for an active lifestyle

    Nice fit, but tank top materials feel hot
    Size: Medium, Color: Dark Grey Heather
    I bought the "dark grey heather" tank. Pros: -comfy relaxed fit (not snug or tight) - armholes not too low - i like the crewneck (but it sits a tiny bit high) - shirt length is a good "normal" length (not short, and not too EXCESSIVELY long like other Amazon brand women's shirts in the past) - looks casual and nice - didn't shrink after machine wash and dry. Cons: - the WORST thing: material feels hot, and it's medium weight, not lightweight like the item description claims. Don't like the 6% ELASTANE, 38% MODAL in this fabric blend. Feels hot in humid hot Houston weather. (But I like the 56% pima cotton!) - the "heathering" (maybe because of the materials) feels like tiny fabric fibers are itching me and not comfortable, especially if the air conditioner is not running, - the hem has side slits and is slightly longer in the back than in the front.

    Perfect fit and comfy
    Size: Large, Color: Black
    I love these shirts! They are soft and lightweight. They fit as they should. I have a black, periwinkle, dark green, and grey. Great tank for the money and perfect to exercise in.

    Quality and comfort!!
    Size: Large, Color: Deep Green
    Beautiful. Very pretty. You can wear this casually or to go out to dinner. The fit was very good. I recommend after washing let it air dry. I was afraid of shrinkage. I bought several, so I can mix and match. The downside with this outfit is it does snag. So be careful.
