Adding a properly designed, thoroughly tested up-pipe is one of the most effective early mods you can make to your Subaru. At GrimmSpeed, our goal was to create a 2-bolt up-pipe that checks every box: precise fitment, long-term durability, strong performance gains — all while meeting modern emissions standards. The result is a SEMA Certified component engineered to deliver on all fronts.

DESIGN:

This up-pipe was developed entirely in-house using our FARO Arm and advanced SolidWorks CAD software, giving us complete control over every detail — from material selection to final fitment. The result is an OEM-header-compatible up-pipe with dead-on accuracy, thanks to ½" CNC-milled stainless-steel flanges and reverse-engineered tolerances based on real-world data.

Each unit is packaged with a set of our proven GrimmSpeed Fire Ring multi-layer steel gaskets and corrosion-resistant zinc-coated hardware — no extra parts or trips to the parts store required. Everything you need is in the box.

We offer the pipe in two finish options to suit your build style: raw stainless steel or our black ceramic thermal coating. The thermal-coated version adds an extra layer of heat control, reducing engine bay temperatures and helping prevent heat soak — all with a cleaner visual footprint under the hood.

MATERIALS:

Only the best local raw materials are used in every GrimmSpeed 2-bolt Up-Pipe.
The flex joint is constructed from 321 Stainless Steel with an interlocking liner for durability, and the tubing itself is made from heavy-duty 14-Gauge 304 Stainless Steel — 33% thicker than most competitors' offerings. Each pipe is CNC mandrel bent for precise, smooth flow, and our ½" thick 304 Stainless Steel flanges are CNC-milled for tight tolerances. For superior strength, each pipe is hand-welded both inside and outside of the flange, ensuring a strong, smooth mating surface for optimal airflow. All fabrication is performed by our Certified Welders/Fabricators, meaning every single up-pipe that leaves our facility is built to handle serious abuse.

PERFORMANCE:

Flow and Boost Response:
You can expect spool times to improve by approximately 300-400 RPM, helping your turbo reach full boost faster and more efficiently. Reducing turbo lag significantly improves overall driving response and power delivery, especially in performance and track applications.

International and Special Shipping Considerations

• International orders are subject to higher shipping fees. If you would like to review your shipping cost, email us at sales@jdmuscleusa.com with your full address and items you plan to purchase.
• In some cases, shipping costs may be incorrectly calculated for international or oversized items. We reserve the right to adjust the shipping fee and will work with you to negotiate a fair cost if needed.
• Customers can challenge and request a review of international shipping fees, and we’ll do our best to find a lower rate where possible.

• Shipping Cost Adjustments: Shipping rates fluctuate, and while we strive to provide the most competitive rates, there may be instances where the shipping cost you paid is significantly lower than the actual cost. In such cases, we reserve the right to request the difference to ensure we cover our basic expenses. We appreciate your understanding and will always aim to keep shipping costs as affordable as possible.

Freight Shipping Guidelines

• Freight shipments require you to be present at the time of delivery.
• The delivery driver may provide a delivery receipt (Bill of Lading). It is crucial to inspect the shipment before signing.
• Carefully check the packaging for any visible damage (dents, punctures, rips) and notate it on the Bill of Lading.
• Open the package and inspect the product itself. If damage is found, document it in detail on the Bill of Lading, take photos, and contact the shipping company to initiate a damage claim.
• Do not refuse the shipment. Contact us at sales@jdmuscleusa.com for guidance.
• If the delivery driver is unable to wait for inspection, note this on the Bill of Lading.

Failure to document damages before signing the Bill of Lading will void any claims for refunds or replacements.
