Flowmaster's® Signature Series Cat-back exhaust system for all 2016-2023 Toyota Tacoma trucks with the 3.5L engine is manufactured using premium brushed 304 stainless steel throughout and features a 2.50-inch inlet pipe leading to a single inlet/dual outlet Signature Series "straight-through" muffler for great sound and performance. This premium exhaust system is TIG welded for a stronger, more precise weld that looks as good as this system sounds. The dual 2.50-inch mandrel-bent stainless steel tailpipes exit out each side at an angle behind the rear wheels directing exhaust away from your boat or travel trailer when towing. The system is finished off with a pair of large 4.50-inch diameter PVD coated black chrome 304S stainless steel tips, giving your truck a custom look that goes hand in hand with that deep performance Signature Series sound. Max dyno gains of 5 hp and 5 lb-ft at the rear wheels. The system uses all the existing factory hanger locations and includes an additional hanger to install the new left side tailpipe. Includes installation instructions and all necessary hardware for an easy installation that you can do at home. Notes: Fits 2/4 Wheel Drive and all Wheelbases.
