Bigger is better. More flow is mandatory when upgrading your Nissan Titan XD Cummins. The aFe POWER Large Bore HD 5" DPF-Back Stainless Steel Exhaust System delivers 65% more flow over the stock exhaust.
A simple bolt-on upgrade, the Large Bore HD uses factory mounting locations and OE-style bayonet hangars for a hassle-free installation. 5" mandrel-bent stainless steel tubing provides smooth transition bends for low turbulence, increasing horsepower, torque and lowering EGT's.
The Titan XD Exhaust is finished with a giant 6" intercooled stainless slash cut exhaust tip, available in black or polished finish.
