So far it looks nice and fit pretty well.
Welds look solid and professional quality, I have not installed them yet but I did put them in place under truck to ensure length and thus far everything looks good. I will give an update after install and on the road with them
Product came in earlier than expected and is made out of high quality materials. SPELAB hasn't let me down yet!!
The product installed perfectly high-quality superior part. For my 2022 f350. Coolant reroute kit.
Everything works great all parts fit hangers fit have pictures if needed
This is a really nice set up inexpensive but well-made. Make sure you use 1/4 inch drive and torque wrench, if you get the half socket 10mm and multi size extensions even better it’ll make getting those two back bolts easy
Makes truck breathe better and will definitely blow your y bridge out so do that while you’re in there looks great and fits up pretty good not perfect
Installed this SPELAB EGR Throttle Valve Delete on my 6.7 Cummins and the fitment was perfect. The kit was well made, installation was straightforward, and all the necessary parts were included. Everything lined up as it should and the truck runs great. Highly recommend for anyone looking for a quality replacement component.
I originally had the Banks Monster Ram intake with grid heater delete, and costed $1200. Recently I decided to give Spelab a try for their 3.5” pusher style intake with grid heater delete. Fraction of the price and performs the same. Only regret I have was my purchase of Banks.
Great product
Good product fast sipping was not that bad of a job
Nicely done ✅
Easy installation and everything fit perfectly. The kit is well-made, comes with the necessary components, and worked as expected. Shipping was fast and the quality exceeded my expectations. Highly recommend for anyone looking for a reliable EGR delete kit.
Very impressed with the quality of the cooler. Couldn’t find any instructions for the install. However, I was able to figure it out and plan to post a video for anyone else who may need help with the install.
Installed this on my 2015 6.7 Powerstroke and everything fit perfectly. Quality parts, straightforward install, and noticeable improvement in engine temps and reliability. Would definitely recommend this kit to anyone doing an EGR delete.
LMM 6.6L DURAMAX 2007.5-2010 FAQ
Yes, the LMM 6.6L Duramax is known for its reliability, especially with proper maintenance.
With regular maintenance, it can exceed 300,000 miles, sometimes more with consistent care and quality parts.
Use a high-quality synthetic diesel engine oil, typically 15W-40, meeting manufacturer specifications for optimal performance.
The LMM (2007.5–2010) added a Diesel Particulate Filter (DPF) for the first time on the Duramax platform. It also retained the EGR system. Both the DPF and EGR are common failure points that degrade performance over time through soot accumulation and cooler cracking.
Yes. The Mini Maxx V2 or EFILive AutoCal V3 tuner is required after deleting the EGR on the LMM. Without tuning, the ECM will flag fault codes, trigger limp mode, and eventually force a forced regen cycle that defeats the purpose of the delete.
The standalone EGR Valve Cooler Delete Kit ($79) removes only the EGR hardware — no tuning included. The All-in-One Kit bundles EGR delete, CCV reroute, and optionally a tuner for a full emissions-off build. Choose All-in-One if you're doing a complete delete in one step.
Yes for standard pickup body styles. The 4"/5" DPF Delete Race Pipe for 2007–2010 LMM is a direct bolt-on. However, it requires tuning to prevent fault codes and is for off-road use only. It is not compatible with Cab & Chassis configurations.
The factory LMM Y-bridge is plastic and prone to cracking under sustained boost pressure, causing boost leaks, surging, and black smoke. The SPELAB 3" aluminum replacement ($178) eliminates this failure point and improves throttle response on any tuned LMM build.
Stock LMM produces 365 hp / 660 lb-ft. A full DPF/EGR delete with performance tuning typically adds 60–100 hp and 100–150 lb-ft torque. Combining a delete tune with an intercooler and intake upgrade pushes gains higher.
Yes. The LMM uses a Variable Geometry Turbocharger (VGT) that can stick or wear out due to carbon buildup — the same issue that plagued the LLY. Deleting the EGR reduces carbon deposits entering the VGT vanes, extending turbo service life significantly.
