Interested in a new exhaust system for your L5P Duramax? Check out the Large Bore-HD dual DPF-Back exhaust system by aFe. This system is constructed from 4" mandrel-bent 409 stainless steel tubing and uses high quality band clamps and OE-style bayonet hangers. This unit uses all factory mounting locations and comes with a bolt-on bracket that supports the driver side tailpipe. This provides for a quick, hassle-free installation with no modification necessary. Also included in this exhaust system are dual polished stainless steel tips with a laser-cut stainless steel aFe power badges. Large Bore-HD exhaust systems are the perfect combination of performance, fit and value.

SINGLE TO DUAL EXHAUST CONVERSION: This exhaust is designed to convert the standard single exhaust into an aggressive dual exhaust.

FITS WITH SPARE TIRE: This exhaust system fits perfectly without relocating the spare tire.

OE FIT: OE-style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. The bayonet tip holds the hanger bushing in place for an OE-style fit that does not change with time.

FLOW AND PERFORMANCE: This Large Bore-HD exhaust system is constructed from 4" mandrel-bent stainless steel tubing for maximum flow. Smooth transition bends allow for low turbulence, increasing horsepower, torque and lowering EGT's.

POLISHED / BLACK TIPS: Finishing off the exhaust are dual high luster, polished or power coated black 304 stainless steel slash-cut tips. This tip features a laser-cut stainless steel aFe power badge for an aggressive style.

Better filter than OEM. Should replace it when you first get the vehicle.
Fits perfectly. Charcoal and paper filter is a huge upgrade from the factory filter.

Perfect fit, solved steering pump noise
Installed this o-ring kit on a 2009 Honda Odyssey. The steering pump was making noise and you could see bubbles in the fluid revivor when the engine was idling indicating a potential air leak from where the hoses attach to the pump. The most difficult part was finding the right 10mm wrench that would allow me to access the lower hose mounting bolt without removing the belt or pump pulley. I wound up taking an old wrench, heated it with a torch, and bent it in a vice to get the right fit. I did order a ratcheting, flex head wrench but while waiting for it to be delivered I was able to make something work. Overall, the o-ring kit worked great, the o-rings seem high quality and this fixed my issue. If you don't already have some, make sure to order the power steering fluid required for Asian/Honda vehicles when you order these o-rings.
