Overview:

The MagnaFlow Chevrolet Suburban/GMC Yukon XL Street Series Cat-Back Performance Exhaust System #19543 drastically improves your 2021 Chevrolet Suburban (Premier/High Country) or GMC Yukon XL Denali by enabling MagnaFlow’s deep signature sound and dyno proven performance to work their magic in improving your driving experience while keeping interior noise in check. Noise control is possible thanks to MagnaFlow’s No Drone Technology (NDT), which uses quarter-wave passive noise cancellation tuned to the specific droning frequency of your Chevrolet Suburban (Premier/High Country) or GMC Yukon XL Denali in order to eliminate exhaust drone. NDT was designed to take the most popular bolt-on modifications into consideration. This cat-back exhaust kit features 3” diameter piping, straight-through muffler, quarter-wave resonators, quad split rear exit and black chrome-finished 4” tips for an extra sporty appearance. The exhaust system is made entirely of stainless steel and was designed from the beginning with weight and ground clearance in mind to improve durability and maintain your 2021 Chevrolet Suburban/GMC Yukon XL’s utility. CNC precision robotic manufacturing and mandrel bent tubing allow for hassle-free bolt-on installation. MagnaFlow stands by the reliability of their products with a limited lifetime warranty.

Surprisingly good shirt for the price
Fit Type: Regular Fit, Color: White, Size: XX-Large
I’m generally pleased with my purchase. I got a 2XL because the website it would fit my neck. Around the waist it fit similar to Amazon Essentials work shirts (like mechanics use which I find comfortable). It was snug around the waist when sitting, but I can’t complain because I have a belly. I did find the neck snug when buttoning the top button so it means the neck is 18 or 18.5 and I wear a 19/19.5 to have 1-2 fingers space in the collar. The shirt is surprisingly thick like Amazon’s work shirts, much thicker than other dress shirts from another brand. And I am pleased that this shirt has button holes like other Amazon shirts does, all vertical button holes except the last one at the bottom which is horizontal. That feature keeps the shirt from unbuttoning itself during daily movement at the office. A very nice feature! I was a little disappointed in how it was packaged however but I have to press and wash it anyway.
