Gen-2 CCV Reroute to Exhaust Kit for 2011+ Ford 6.7 Powerstroke F250 F350 F450 F550
Camron Presley
Quality product and loaded kit

This kit came with everything I needed to get the job done. There's a great SPE lab video online for installation help. Every piece felt quality and was simple enough to put together. Had extra hose after running all the way to the back of my rig so there's plenty provided. I just ran mine to atmosphere so there's a popcorn sound at the back of my rig now but it doesn't smell terrible. Definitely recommend this upgrade for anyone who wants a healthy engine. As for how hard the installation is, if you can change the CCV box you can install this kit.

Thermal Bypass Valve for 2013–2024 Dodge Ram 2500/3500 6.7L Diesel | SPELAB
Jay Combs
Works perfectly - Note on the O-rings!

Installed this SPELAB thermal bypass valve alongside a deep pan upgrade and the setup works flawlessly. Trans fluid temps drop fast and stay right where they should be.

The overall fit was great and the build quality feels solid. I noticed a past review complaining about the O-rings being the wrong size—just wanted to clarify that those O-rings aren't for the bypass block itself; they are meant for the metal threaded filter adapter. Don't let that review throw you off. Solid 5 stars!

Not on public roads in the U.S. The Clean Air Act prohibits removing factory mufflers as they are certified emissions components. Noise regulations vary by state and city—most require a muffler for on-highway vehicles. Muffler deletes are strictly off-road and race-use only. If you need a louder exhaust on a street truck, consider a flow-through muffler or a dual-mode exhaust system instead.

Expect a significant volume increase over stock. Most diesel trucks gain 5–10 dB with a muffler delete, and the sound shifts from muffled rumble to a raw, tractor-like drone at highway speeds. The tone also changes—lower-frequency exhaust notes become more pronounced without the baffling of a factory muffler. Test fit a straight pipe section first if possible to gauge your tolerance before committing.

Yes, drone is the most common complaint with muffler deletes. Drone is a resonant low-frequency vibration that becomes most noticeable at 1,500–2,500 RPM (cruising speed). Longer wheelbase trucks (like the Ford F-250/F-350) are more prone to drone due to longer exhaust pipe length. Adding a Helmholtz chamber resonator or switching to a glasspack-style muffler reduces drone while still opening up the exhaust note.

Modest gains only. A muffler delete reduces exhaust backpressure slightly, which can improve turbo response and slightly raise peak power. Real-world results are typically 5–15 HP on a stock or mildly tuned diesel. The power gain is much smaller than a downpipe, delete kit, or intake upgrade. Choose a muffler delete primarily for sound, not for performance.

Yes. Most SPELAB muffler delete pipes use band clamps or slip-fit connections at the factory muffler location. If your truck has a welded muffler assembly, you'll need to cut the pipes and either weld on new flanges or use a clamp-on adapter. Most late-model diesel trucks (2010+) have bolt-on mufflers that make the delete a straightforward 30–60 minute job with basic tools.
