Does the Charge Pipe Kit for Chevrolet Silverado HD trucks also fit the GMC Sierra HD?

Yes. HPS lists the same kit for the 2013-2016 GMC Sierra 2500 HD and 3500 HD with the 6.6L Duramax LML, alongside the Chevrolet Silverado 2500 HD and 3500 HD of the same years, across the trims HPS names from WT and Base up to High Country and Denali.

Will this kit fit a 2017 or newer Duramax truck?

No. The 2017-2019 trucks carry the L5P engine, and HPS makes separate hot side and cold side pipes for it. This kit is listed only for the 2013-2016 Silverado HD and Sierra HD with the 6.6L LML, so check the model year and engine code before ordering.

Why stainless steel instead of aluminum?

HPS chose 304 stainless steel because it tolerates higher pressure and temperature than aluminum and resists corrosion. The Charge Pipe Kit for Chevrolet and GMC LML trucks uses 16-gauge mandrel bent tubing, 3-1/2 inch on the cold side and 3 inch on the hot side, in place of the factory pipes.

What comes in the box?

The kit includes both stainless steel pipes, fluorolined reinforced silicone boots, stainless steel spring-loaded T-bolt clamps and a step-by-step installation manual with photos. HPS designed the boots to resist the oil blow-by common on these engines, where the factory pipes and boots are prone to leaks and cracks.

How hard is the installation?

HPS states that no modification is required, and the two-piece pipe design is meant to make fitting and later service easier. The included manual guides the installer through each stage with clear photos and written instructions. HPS does not publish an install time for this kit.

HPS Hot and Cold Side Charge Pipe Kit for Chevrolet Silverado HD and GMC Sierra HD LML

HPS’s Hot and Cold Side Charge Pipe Kit for Chevrolet Silverado HD and GMC Sierra HD LML trucks swaps both factory intercooler pipes on the 2013-2016 6.6L Duramax for mandrel bent 304 stainless steel. The cold side runs 3-1/2 inch tubing and the hot side 3 inch, both in 16-gauge wall, and each joint is made with fluorolined silicone boots made to resist the oil blow-by common on these engines. It suits the LML owner who tows hard, has added power or is done chasing leaks at the stock boots.

Design and Performance

HPS picked stainless over aluminum here because it handles more heat and pressure and resists corrosion, a sensible trade on a diesel that spends much of its life under load. HPS cites sharper throttle response and lower exhaust gas temperatures, yet publishes no dyno figure for the LML, so treat this Charge Pipe Kit for Chevrolet and GMC diesels as a reliability upgrade first. If only one side has failed, HPS also sells each pipe on its own.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
