Overview:

The MagnaFlow Chevrolet Tahoe/GMC Yukon Street Series Cat-Back Performance Exhaust System #19580 drastically improves your 2021 Chevrolet Tahoe High Country or GMC Yukon 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 Tahoe High Country or GMC Yukon 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 Tahoe/GMC Yukon’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.

Great replacement parts!
Perfect fit for my 2003 Mercury Salt Water 150 2 stroke engine. Everything I needed was in the box.” “Good quality parts and saved me a lot compared to OEM.

Great connectors
Size: 5 pairs
Just finished an overhaul on the stereo system. A couple decks needed new belts and the wife wanted a new cabinet for everything so just take it all apart and refresh. I ordered these plugs to make the backside wiring a bit neater . They are very well made and easy to install if you mess up the polarity just swap the arrel covers, easy peasy. Great quality and easy assembly. Did it improve the sound? Can't say that I noticed that but it is certainly as good and so much easier to connect speaker outputs. I would certainly buy again.
