The MagnaFlow 19603 is a Street Series cat-back exhaust for the 3.4L V6 in 2022-and-newer Toyota Tundra trucks. It starts just behind the catalytic converter and replaces the factory piping from there rearward, so the stock cats stay in place. A 3-inch mandrel-bent stainless main pipe feeds a straight-through muffler and two 3.5-inch black-coated tips that exit behind the driver-side rear tire. Owners looking for a 2022 Tundra 3.4L cat-back with a dual driver-side rear exit will find this kit's layout is the main draw.
The manufacturer describes the sound as aggressive outside and moderate inside, which suits a truck that is driven daily. It says the system was dyno-tested to improve exhaust flow, and it credits mandrel-bent tubing with smoother gas transitions than crush-bent pipe. No horsepower or torque figures are published, so treat any gains as qualitative. The stainless construction and CNC robotic fabrication are the durability argument for paying more than a basic mild-steel system.
Installation is bolt-on. The manufacturer's listing says clamps and hangers are included, but no gasket or seal is, so plan to source those separately. The manufacturer notes that basic automotive knowledge is needed and that professional installation is always recommended, and an install guide is available for download. Owners on user forums report some drone at cruising RPM with aftermarket cat-backs on this truck, so set expectations accordingly.
No. The manufacturer's specifications state that no gasket or seal is included, so you will need to source one separately before installation.
No. The manufacturer states the kit replaces the exhaust components from near the catalytic converter rearward, so the factory catalytic converters remain in place.
The manufacturer's current product page lists a 2022-2027 fitment range for the 3.4L Tundra, while an earlier version of its page listed 2022-2026. Confirm your year, trim, and engine with the manufacturer's fitment lookup before ordering.
The manufacturer says the install requires basic automotive knowledge and recommends professional installation. A downloadable installation guide is available from the manufacturer.
This is a bolt-on cat-back, so it does not require welding, and the manufacturer provides an install guide that covers the sequence and hardware placement. The manufacturer's guidance is that basic automotive knowledge is needed and that a professional install is always recommended. Because no gasket is included, buy new gaskets before you start and do not plan to reuse worn ones. Before tightening everything, check that the pipe and tips clear the rear bumper and the spare tire area, and confirm that the hangers sit correctly, since clearance is where most cat-back installs run into trouble.
