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.

Good Plug if you need this model
These are the OEM for Kohler 7000 series I did service on. They needed to be gapped but that’s every spark plug.

Go Ridding and Go Flatless with QuickStrike tire sealent
Size: 1 Gallon + Tool, Set name: Off-Road Formula
I’ve tried several tire sealants over the years on my ebikes and scooters, but FlatOut QuickStrike is by far the best I’ve used. From the moment I added it to my bike tires, I noticed a difference—it’s incredibly easy to install, and you don’t have to convert to tubeless to benefit from its protection. The formula is thin and spreads quickly, sealing punctures almost instantly so you don’t lose much air. What I feel that really stands out is how effective it is. I ride my ebikes through rough terrain with lots of thorns and debris, and since using FlatOut QuickStrike, I haven’t had a single flat ( unlike before ). Even when I’ve picked up multiple punctures, the sealant has handled them all without a problem. I feel that the peace of mind it gives me is priceless, especially on long rides or commutes where a flat could ruin your day ( and It has in the past ). Another big plus is that it’s a one-time application—it won’t dry out or turn into a mess inside your tire ( like that Green Stuff ). It’s also safe for both tubes and tubeless setups, and works well in my 20 inch and 14 inch tires. I’ve used it on my ebikes and scooters and the results have been consistently impressive. Make me feel confident of the durability of my tires on my ride. I bought the gallon bottle because I have a few ebikes and scooters. this stuff works great! If you want to spend less time fixing flats and more time enjoying your ride, this is the sealant to get. Highly recommend!
