The BORLA RD Team has designed a great performance Cat - Back system for the Nissan Titan. The 2.25 diameter BORLA system is True Dual. The muffler contains an internal H - Pipe for increased performance and improved sound. This Cat - Back system is going to deliver a significant improvement in sound that will give your Titan a more exciting driving experience. The BORLA S - Type sound level is specifically tuned for performance and sound on the Nissan Titans 5.6L V8 engine giving the truck a proper V8 growl and the distinct BORLA sound. As expected from BORLA, the system is drone - free to ensure an enjoyable ride. This system features 4 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. The system is made of T - 304 stainless steel and comes with the BORLA Million Mile Warranty. Bolt on a BORLA and hear the Titan roar
