The muffler contains an internal H-Pipe for increased performance and improved sound. This system delivers a significant improvement in sound that will give your Titan XD a more exciting driving experience. The classic Borla S-Type sound level is specifically tuned for performance and sound on the Nissan Titan XD's 5.6L V8 engine giving the truck a proper V8 growl and the distinct Borla sound with no drone inside he vehicle. This system features 2 full Tail Pipes (Not a single tail pipe with dual tips) and 4 in. round bright chrome on T-304 stainless steel tips. A system with black chrome on T-304 stainless steel tips is also available. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit.
