    Product DetailsCustomer ReviewsRelated ProductsRecently ViewedBack to Top

    The factory exhaust manifolds on your GMT900 Silverado or Sierra are one of the first restrictions holding back your LS engine. This complete full kit pairs Speed Engineering's 1-7/8" longtube headers with a 3" off-road Y-pipe that connects directly to the existing cat-back location — replacing the restrictive factory exhaust manifolds and mid-pipes with a free-flowing stainless system designed for significant horsepower gains, improved throttle response, and a deeper, more aggressive exhaust tone. Dyno proven to deliver over 25 rear-wheel horsepower over stock.

    Built from 304 natural stainless steel with mandrel-bent primary tubes, merge spikes, CNC-machined flanges, and full TIG-welded construction.

    ⚠️ Important Notes:

    • Rear downstream O₂ sensors are not used — a check engine light for catalyst efficiency will appear and must be disabled via PCM tuning
    • Y-pipe is compatible with 6-speed automatic transmissions
    • Depending on factory exhaust configuration, some cutting or welding may be required for Y-pipe installation
    • 2007 Classic body style: These headers will NOT fit the 2007 Classic (carry-over GMT800 body). 2007 Classic owners should purchase 1999–2006 exhaust products instead

    Kit Includes:

    • 1 Pair of 1-7/8" Stainless Longtube Headers
    • 1 Three-inch Off-Road Y-Pipe / Connection Pipe
    • 1 Set of Zinc-Coated Header Bolts (upgrade to stainless ARP bolts available at checkout)
    • 2 MLS Exhaust Gaskets

    Optional: Speed Engineering LS Spark Plug Wires and Plug Wire Fire Sleeves can be added at the time of purchase.

    Features:

    • Full 1-7/8" Primary Tubes with Merge Spikes — Full-diameter flow from cylinder head to collector for maximum exhaust scavenging
    • 3" Collector — Optimized for strong low-to-mid RPM torque
    • Mandrel Bent Tubing — Consistent tube diameter through every bend; no crimping, no restriction
    • CNC Machined Flanges — Precision fit at the head and collector for a leak-free seal
    • 304 Natural Stainless Steel Construction — Corrosion resistant, heat tolerant, and built to last
    • Longtube Header Design — Maximum scavenging efficiency vs. shorty or mid-length headers
    • Standard Graphite Manifold Gaskets Included
    • Dyno Proven — 25+ RWHP gain on 4.8L, 5.3L, 6.0L, and 6.2L applications
    • Compatible with 4.8L, 5.3L, 6.0L, and 6.2L LS V8 Engines
    • V8 Engines Only

    Frequently Asked Questions:

    Q: What is the difference between this kit and the 1-3/4" headers-only listing (25-1013)? Two differences: this kit includes the Y-pipe, header bolts, and MLS gaskets in addition to the headers, and the primary tube diameter is 1-7/8" vs 1-3/4". The 1-7/8" headers offer a step up in flow for builds with supporting modifications. Choose the full kit for an all-in-one purchase; choose the headers only if you already have or plan to source the Y-pipe separately.

    Q: Will I get a check engine light after installing this kit? Yes. The rear downstream O₂ sensors are not used with this system, which will trigger a catalyst efficiency code. This must be resolved through PCM tuning and cannot be cleared by simply resetting the ECU.

    Q: Does the Y-pipe work with my transmission? The Y-pipe is confirmed to work with 6-speed automatic transmissions. Depending on your factory exhaust configuration, some cutting or welding may be required for Y-pipe installation.

    Q: Will these fit the 2007 Classic Silverado or Sierra? No. These headers are for the 2007 new body style (GMT900) only. 2007 Classic (GMT800 carry-over) owners should purchase 1999–2006 exhaust products instead.

    Q: What is included in this kit? The kit includes a pair of 1-7/8" stainless longtube headers, a 3" off-road Y-pipe, two MLS exhaust gaskets, and zinc-coated header bolts. An upgrade to stainless ARP bolts is available at checkout. Speed Engineering LS spark plug wires and plug wire fire sleeves can also be added at the time of purchase.

    Q: How much horsepower does this kit add? Speed Engineering's 1-7/8" longtube headers are dyno proven to add over 25 rear-wheel horsepower on 2007–2013 GMT900 applications compared to stock exhaust manifolds.

    Q: What material are these headers made from? 304 natural stainless steel with full TIG-welded construction, CNC-machined flanges, and merge spikes.

    Q: Are these headers street legal? No. These are race-only headers intended for closed-course competition use only. Installation on a street-driven vehicle may violate the Clean Air Act (42 U.S.C. 7522(a)(3)).

    ⚠️ Race Use Only: This product is manufactured and sold for installation on vehicles used solely for competition. Once installed, the vehicle may not be used, registered, or licensed for use on a public road or highway. Installation on a street-driven vehicle may violate the Clean Air Act 203(a)(3), 42 U.S.C. 7522(a)(3).

    We want you to love what you ordered. If something isn't right, here's everything you need to know.

    30-Day Return Window

    You have 30 days from the date of purchase to initiate a return. After this window, we are unable to accept returns. We do not offer exchanges — all approved returns are refunded per the terms below.

    How to Initiate a Return

    To request a return, contact us at sales@berryperformancesales.com with your order number and reason for return. All returns must be approved by our team before any item is shipped back to us. Once your return has been approved, your item must be shipped within 10 days of approval. Items shipped without prior approval or outside this window will be refused and returned to sender.

    Return Conditions

    To be eligible for a return, items must be:

    • Unused and in original condition
    • In original packaging
    • Inclusive of all parts and accessories

    Custom ordered products are non-returnable. If you're unsure whether your item qualifies, contact us before purchasing.

    Once we receive your return, we will inspect the item before processing any refund. We reserve the right to deny or adjust your refund if the item is received in a condition that differs from what was originally shipped — including signs of use, missing parts, or damage that occurred after delivery.

    Fees to Know Upfront

    We believe in being transparent about costs:

    • Restocking Fee: 20% — deducted from all return refunds
    • Return Shipping: Buyer's responsibility on all standard returns
    • Cancellation (Installment/Payment Plan): 7% fee to cover transaction costs
    • Cancellation (Credit Card/PayPal): 3.5% processing fee

    If your order arrives damaged or defective, you must contact us within 48 hours of delivery at sales@berryperformancesales.com. Claims reported outside this window may not be eligible for resolution.

    When contacting us, please include:

    • Your order number
    • A description of the issue
    • Clear photos or video of the damage or defect

    If your item was damaged during shipping, this is handled as a carrier claim separate from our standard return process — we will assist you in filing that claim. Items confirmed to be defective due to a manufacturing or fulfillment error will have return shipping costs covered by Berry Performance Sales.

    Refunds

    Once we receive and inspect your return, refunds are processed within 3–5 business days back to your original payment method. You'll receive a confirmation once it's been issued.
