If you're looking to improve the sound of your 2004-2008 Triton V8 engine, look no further than an aftermarket cat-back system. Made from corrosion resistant T304 or T409 stainless steel and featuring either 2.5" or 3" piping, aftermarket cat-backs provide smooth and quick exhaust flow which in turn produces less back pressure at the cylinder head and a natural deep sound that is more akin to something we would expect from a V8 F-150. Single-chamber mufflers will pop and crackle over the entire RPM range whereas a baffled or multi-chamber muffler, while still throaty and authoritative, will be somewhat more subdued. By design, all aftermarket cat-back kits are intended to be a bolt-on affair, meaning no cutting or welding of the pipes is necessary. Kits are presented with the choice of a side exit tip or a conventional rear exit setup. Couple a cat-back with specific 2004-2008 F-150 headers and you will not only have one mean sounding truck, but one that has the bite to match the bark.
