Q1: Will this PCV reroute kit fit my 2014 Chevy 2500HD with the LML Duramax?
A1: Yes! This lml pcv reroute kit is a direct fit for all 2011–2016 6.6L Duramax diesel engines, including Chevrolet Silverado and GMC Sierra 2500HD/3500HD models. (Note: For 2.8L Duramax owners, we also offer specific kits designed for the 2016-2022 Chevrolet Colorado and GMC Canyon.)
Q2: Is an lml pcv delete necessary for my truck?
A2: While not mandatory, an lml pcv delete is highly recommended. The stock system vents oily mist into the intake; rerouting it prevents carbon buildup, protecting your turbocharger and intercooler from performance-robbing sludge.
Q3: What are the main benefits of an lml ccv delete for engine longevity?
A3: By performing an lml ccv delete, you ensure only clean air enters the combustion chamber. This prevents "gumming up" of intake valves and intercooler boots, resulting in a cleaner engine and improved combustion efficiency.
Q4: Do I need a tuner to install this PCV reroute lml kit on my Duramax?
A4: No tuning is required for the pcv reroute lml itself. However, for full delete setups (DPF/EGR), a compatible tuner like Mini Maxx, EFILive, or EZ Lynk is necessary to prevent "Limp Mode" and clear diagnostic codes.
Q5: Will this help with "Service Exhaust System" or "Limp Mode" issues?
A5: While the PCV kit improves intake health, full delete kits for the 2.8L or 6.6L Duramax are designed to permanently solve DEF fluid quality sensor failures and the dreaded "Speed Limited to 4 MPH" messages.
Q6: Is the installation difficult and what is the typical cost?
A6: Our kits feature a bolt-on installation that usually takes about 1 hour. While a PCV kit is affordable, a full delete setup for a 2.8L or 6.6L Duramax typically ranges from $900–$1,400 depending on the tuner and hardware selected.
Q7: Is this kit legal for street use?
A7: This product is intended for competition off-road use only. Please check your local and federal regulations before installation, as it may not be emissions-compliant for on-road use in certain states.
Q8: Do I need a tuner to install this kit on my Duramax?
A8: No tuning is required for this Duramax PCV reroute. However, if your truck is deleted, pairing it with a tuner like Mini Maxx can help clear potential CEL codes.
Q9: Will this PCV reroute cause oil leakage?
A9: Minimal oil misting is normal. To prevent leaks, make sure all fittings are tight and hoses are properly secured.
Q10: How does this reroute compare to the stock PCV setup on LML Duramax?
A10: The stock system vents oil vapor back into the intake, leading to sludge and gumming. Our LML Duramax PCV reroute kit vents externally, keeping your intake dry and your engine healthier.
Q11: Is this kit emissions-compliant?
A11: This product is intended for off-road use only and may not comply with emissions regulations in certain states.
Customer Reviews
The reroute kit was high quality and easy to assemble it really cleaned up the space on my 2014 lml .
Let customers speak for us
The reroute kit was high quality and easy to assemble it really cleaned up the space on my 2014 lml .
The price doesn’t Reflect on the product. Very high quality heavy duty parts . The only thing lacking is instructions that would have put this kit over the top . I did the full lml delete and pcv reroute . The kit doesn’t come with the up pipe you have to order that separate.
Better sound, more power. Love it!
Purchased SPE delete for a F450. Was a little more than I could do to install. Took to my mechanic who installed it. He couldn't stop raving about the quality of the kit, and the difference it made in the truck's performance. This truck would endlessly code saying "cleaning exhaust filter" over and over. All of that nonsense is gone, the truck runs 100% better. AND went from 8.9 mpg to 15.1 mpg! Overly satisfied!
Everything went together good besides having to figure out the installation with only pictures. A video or better installation instructions would have been very helpful. Truck runs and sounds great now!
I was a little scared it would make the truck sound like a soda can but it actually sounds deeper and way better so I can’t complain easy to install ( if you have the long bed you may need to cut back 4” off one of the middle pipes to get the hangers to line up very easy solution make sure you cut the side that doesn’t have a bell end)
be sure to update mini Maxx with the latest firmware 2.0.0.8 FIRST! I learned that lesson😟
I also on my 2019 ram ended up plugging OBD bypass into middle row fourth one up after doing that I got zero codes truck runs great !! customer service isn't a whole lot of help mini maxx responds to emails but not quickly.
The product is great. Does what it's designed to do.
The instructions? Not so much. Luckily, the Customer Service people do their best when emailed and walk you through the process start to finish. The only other thing I'd like to see are the basic beginning settings for setting up "defuel". Every engine is different (Ford/Chevy/Dodge) and finding this info through forums is terrible.
I currently have the DPF deleted, the EGR turned off, and the race pipe has a 27" stainless resonator added to keep it quiet. It rolls coal on "Extreme" and the increase in power on "Stock" is very apparent. I run it on "Stock" 100% of the time and gained over 2 mpg so far on the first tank.
2013 F350 Crew Cab Dually 50225 miles on odometer. No rust anywhere, pristine Cali truck. I guess the original owner couldn't afford to drive it. LOL
It was packaged very nicely, quality is top notch and installation was very easy. Had installed in about an hour. That was taking my time and removing the old exhaust. Would highly recommend!
The craftsmanship is superb and wish I could say the same for the OEM Plastic CCV box. The four security screws were challenging and used Irwin external extractors versus easy outs.
I received both the EGR and Downpipe delete kit quick but there is no Tuner! No tracking number for the tuner and says all my parts have been delivered! What the heck no one spent a grand on a straight pipe and EGR! However they did fix it promptly and I did receive the tuner! So I would say five stars
Honestly, the exhaust was much nicer than I expected fitment wise. It fit just as well if not better than exhaust systems I have installed in the past that were a few hundred more dollars. Shipping time was pretty good as well… received it the same week I ordered it. That’s about all I can speak on for now as I have only put about 100 miles on it.
Everything you need and nothing you don't. The parts install really impressively smoothly.
Could definitely use better / ANY instructions, especially since youtube vids on deleting trucks have been taken down lately.
It took a day of searching and watching vids here and there to find out it is extremely important to go in a certain order:
1: install the tuner first
2: install a "smog equipment has been removed" tune even though the truck still has the equipment at the moment.
3: remove the dpf and egr bits
Money well spent. Install was simple. Do not misunderstand simple with easy. Although it was easy for me. Install of the MINI MAXX V2 was a bit different. The video provided on the site was not how my installation went. In fact it was very different. With that, it did go as expected. The tuner does have some what of a learning curve, not very much info out there now with all the bureaucratic garbage we, in the US, have to contend with. It is out there, just TOUGH to glein. The removal of that gargantuan nightmare of an exhaust filter was not for the faint of heart. It is heavy, and the connectors on all those sensors can be challenging. It will be worth the struggle. The removal of the Extra Grace Required part was the hardest part for me. Having had my exhaust and turbo out 2 times, one of the bolt heads got damaged in the last re-install. That took a huge amount of patience and correctly applied downward force and a special tool. FYI THE PYROS DO NOT READ CORRECTLY ON 2011 F350 IT WILL ONLY READ 1193°!
Then the block off bypass parts, easy install. Looks great and does everything I expected. As a plumber I was able to use some expansion couplings and cut the water tubes and did not use the supplied hose. Then back on the ground to install the exhaust pipe. That was a challenge. The hanger bracket wasn't quite on par and was bent a bit. Nothing like a torch and a quality set of Pittsburgh 3/4" box end wrenches. Got that squared away, lined everything out and the slip joint went in nicely. I only used one of the 3 bolt flange bolts because I saved 2 of the pressed in studs. The down pipe connector flange was a special kind of hurrah. Perseverance, busted knuckle, and lots of upward pressure, accomplished that.! Overall I like the kit, don't like it doesn't come with instructions, but if you're buying this kit I'm betting you're already a mechanic anyway. HUGE THANKS TO SPETUNER.
One more thing, FedEx delivered my 1st kit to 2 wrong addresses, SPETUNER made it right and sent out a new kit for my. That is worthy of my review!
Fast delivery, great product was exactly as described.
