MagnaFlow Street Series Cat-Back Exhaust Now Available for 2021 Chevy Tahoe

The Golden Bowtie charges $1,645 to $2,145 for a cat-back exhaust that unlocks as many as 11 horsepower and 6 pound-feet of torque. MagnaFlow, by comparison, asks $1,091 to $1,489 for the Street Series Cat-Back Performance Exhaust System with 3.0-inch tubing and black tips.

Compatible with the Tahoe, Suburban, Yukon, Yukon XL, and both versions of the Escalade, this aftermarket option utilizes quarter-wave passive noise cancellation. In other words, don’t expect and unwanted droning at certain engine speeds. The bolt-on exhaust system further boasts a straight-through muffler, 4.0-inch single or dual exhaust outlets, stainless-steel construction, CNC precision manufacturing, as well as mandrel-bent tubing.

Backed up by a lifetime construction warranty and one year for the finish, the Street Series doesn’t need specialized equipment to be fitted onto the vehicle. A 3.0-inch clamp, a wrench, three sockets, and a hanger tool or a pry bar are listed in the installation manual. If push comes to shove, spray lubricant should be enough to get the bone-stock exhaust off the vehicle.

MagnaFlow doesn’t give any estimates for the horsepower and pound-feet gains, but then again, these truck-based SUVs were never intended to go fast. As the name implies, the Street Series is meant to sound good and look good without compromising the factory calibrations or the factory NVH levels.

On that note, the most affordable full-size SUV that GM sells for the 2021 model year is the Tahoe. The rear-wheel-drive LS trim level with the 5.3-liter V8 and 10-speed automatic retails from $50,295 excluding freight, while the 6.2-liter option will set you back $70,895 for the High Country.
