TruckTok 2008-2010 Ford 6.4L Powerstroke 5" Dp-Back DPF Delete Pipe(With Muffler)

2009 F-250. My factory DPF cracked internally and started throwing P2002 and P244A codes. Ford wanted $3200 for the replacement DPF assembly. I spent $1200 on this TruckTok 5-inch race pipe and a tune. The truck runs better, sounds better, and I saved two grand. The DPF on a 6.4 is a consumable part — they all fail by 120K. Replace it once the right way with a delete pipe.

2010 F-350 in Wisconsin. Two winters of road salt and the TruckTok 5-inch pipe still looks good underneath. The 304 stainless is properly polished and the welds have not shown any rust. The band clamps are stainless too — no rusty fasteners. I had a cheaper 409 stainless exhaust on my last truck that rusted through in one winter. This is the real deal.

Our 2008 F-450 pulls a 4-horse gooseneck. Before the delete, EGTs on the long grade would hit 1250 and I would have to back off. After this TruckTok 5-inch pipe, we peak at 1050 on the same grade with the same load. The horses are less stressed, the truck is less stressed, and I am less stressed. The 5-inch diameter is key — a 4-inch pipe still restricts the 6.4's compounds at high load. This pipe flows like a freight train.

2010 F-250. The 6.4 engine bay is packed. I did this install cab-on and it was a fight — the downpipe section barely squeezes past the firewall and the heater box. Took about 5 hours solo. If you are already pulling the cab for studs or turbo work, install this pipe then. The 5-inch tubing is physically large and the routing through a cab-on 6.4 is tight. That said, the system fit once in place and has not rattled or leaked.

If you want a quiet truck, delete with a 4-inch pipe and keep a muffler. This 5-inch TruckTok system is loud. At idle it rumbles, at highway speed you hear the exhaust, and at full throttle it roars. I personally love it — the compounds sound incredible — but my neighbor who leaves for work at 4am does not. Four stars because I wish I had been warned about the volume. It is not obnoxiously loud but it is definitely not subtle.

The 6.4 Powerstroke has a terrible reputation, and the DPF system is 90% of the reason why. Regeneration dumps fuel into the oil, dilutes it, and washes the cylinder walls. That leads to scored cylinders, cracked pistons, and bottom-end failures. This TruckTok 5-inch delete pipe plus a tune stops that cycle completely. My 2010 had 105K miles with a failing DPF and is now at 150K with zero engine issues. Do not wait for the DPF to destroy your 6.4.

2008 F-250 crew cab. This is a true downpipe-back system — includes the downpipe section, mid-pipe, and tailpipe all in 5-inch 304 stainless. The downpipe section clears the compound turbo plumbing and the transmission. The polished tip is rolled edge and fits the factory bumper cutout. Every clamp, gasket, and hanger is included. Took a Saturday with basic tools. If you are going to delete a 6.4, get a complete kit like this — do not try to piece it together.

2010 F-350 dually. The 6.4 is thirsty even without a DPF, but with it I was getting 12 mpg highway empty. After this TruckTok 5-inch race pipe and a tune, I get 19 mpg. The math: at $4 diesel and 20K miles a year, that is about $250 a month saved. The pipe paid for itself in three months. The 5-inch is perfectly sized for the 6.4 — the compounds move a lot of air and need a big pipe downstream.

2009 F-450. The 6.4 has compound turbos — a small atmospheric and a large high-pressure — and the factory DPF silences all of that. This 5-inch TruckTok pipe lets the compounds sing. The turbo whistle builds like a jet at spool and the tone is deep and clean. The 5-inch diameter gives it a big-rig sound, not a raspy straight-pipe. If you have a 6.4 and you have not heard it deleted, you are missing half the engine.

2008 F-250. The 6.4 DPF regen cycle injects raw diesel into the cylinders on the exhaust stroke. At 80K miles my oil analysis showed 5% fuel dilution — basically diesel soup in my crankcase. Installed this TruckTok 5-inch downpipe-back race pipe and a delete tune. Next oil change at 5000 miles showed 0.5% fuel dilution. The 6.4 is actually a great engine once you remove the emissions that are trying to kill it.
