    Looking for a budget-friendly, leak-free exhaust solution for your LT swap that tucks in tight and keeps a clean traditional look? Speed Engineering's cast iron LT swap exhaust manifolds offer improved flow over a factory manifold with a 2.25" outlet and 2.5" V-band exit flange configuration — without the fitment complexity or cost of stainless longtube headers. Cast iron construction means excellent durability and less valve noise compared to traditional shorty or longtube headers. The tight tuck design fits most popular classic GM chassis for a clean, sleeper-friendly appearance.

    ⚠️ Important Installation Notes:

    • Gen V LT direct injection engine swaps only — these manifolds are NOT compatible with SBC or BBC engines
    • 4L80E or older Turbo 350/400 transmission — bellhousing ears may need to be trimmed for proper clearance due to tight fitment
    • 1968–1974 Nova and 1968–1972 Chevelle early 1960s applications require an aftermarket steering shaft

    Features:

    • Cast Iron Construction — Durable, heat-resistant, leak-free sealing designed for long service life in LT swap applications
    • 2.25" Outlet Diameter — Improved flow for maximum performance from a cast iron exhaust manifold
    • 2.5" V-Band Exit Flange — Clean, secure connection to your exhaust system
    • Tight Tuck Design — Universal fit for most popular classic GM chassis with a clean traditional muscle car appearance
    • Less Valve Noise Than Headers — A quieter, more refined driving character compared to shorty or longtube headers
    • Gen V LT Swap Conversion Manifolds
    • V8 LT Engines Only

    Vehicle Applications:

    Note: All applications listed are Gen V LT swap conversions. These manifolds are not compatible with the original factory engines in these vehicles.

    Frequently Asked Questions:

    Q: What is the advantage of cast iron manifolds over stainless longtube or shorty headers for an LT swap? Cast iron manifolds offer excellent durability and leak-free sealing with less valve noise than traditional shorty or longtube headers — making them a great choice for street-driven LT swap builds where a quiet, traditional muscle car look is the goal. They also tend to be more budget-friendly than full stainless header setups.

    Q: What connection type do these manifolds use? These manifolds feature a 2.25" outlet diameter with a 2.5" V-band exit flange for a clean, secure connection to your exhaust system.

    Q: Will these work with my SBC or BBC engine? No. These manifolds are designed for Gen V LT direct injection engine swaps only and are not compatible with SBC or BBC engines.

    Q: Do early 1960s Nova and Chevelle applications require any additional parts? Yes. Early 1960s Nova and Chevelle applications require an aftermarket steering shaft for proper fitment.

    Q: Will these fit with a 4L80E or older Turbo 350/400 transmission? These manifolds may require trimming of the bellhousing ears on 4L80E or older Turbo 350/400 transmissions for proper clearance due to the tight fitment design.

    Q: Are these manifolds street legal? No. These are race-only products 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)

    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.

    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.

    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.
