RemTune 90 Degree 3″ Stainless Pie Cuts
Category: Raw fabrication components. These are individual unwelded segments intended for custom projects. They require welding to assemble into a finished pipe or exhaust system. Not a complete exhaust — for experienced fabricators and builders.
Material and finish: Premium 304 stainless steel (AISI 304) for strength, corrosion resistance, and heat tolerance. Built to handle demanding fabrication applications on any vehicle.
Geometry and performance: Tight 90° radius cut designed for maximum flow. The geometry minimizes turbulence, aiding smoother exhaust flow and more predictable performance outcomes.
Best for: Experienced fabricators who need modular pieces they can weld into a custom exhaust layout. Pick this if you want a proven tight-radius option that fences off excessive turbulence.
Limitations: Not a turnkey exhaust solution; requires skilled welding and fitting. Careful handling is advised to maintain edge quality prior to installation.
Piclafe 3″ Pie Cuts — 5 Pcs, Polished
Configuration-friendly: Each 3″ OD pie cut supports bends up to 90 degrees and can be arranged in multiple configurations for custom routing.
Material and finish: 304 stainless steel with mirror-polished edges. Precisely cut and deburred for clean welds and a professional finish.
Best for: Builders who want an aesthetically polished finish with reliable stainless steel performance. Suitable for visible sections of an exhaust or fabrication project where finish matters.
Limitations: Comes as separate pieces; assembly and welding are required to complete the system.
Tigtonic 3″ 90° Stainless Pie Cuts (6pcs)
Fully customizable: These sections can be arranged in configurations up to a 90° bend. They come deburred and polished to support immediate welding straight from the box, saving fabrication time.
Material: 304 stainless steel with a 3″ outside diameter. The ready-to-weld finish helps reduce prep work on job sites.
Best for: Shops needing a straightforward set of ready-to-weld pie cuts that minimize finishing steps before installation.
Caution: Ensure the chosen configuration matches your intended routing; misalignment can require rework at the weld seams.
WUMZIJ 3″ Pie Cuts — 5 Pcs, Polished
Material and finish: Premium 304 stainless steel with a mirror-polished surface. Each piece includes a protective plastic film to guard edges during transport.
Size and fit: 3″ outside diameter with thickness around 1.3 mm; polished to maintain smooth weld joints and clean interior flow.
Best for: Projects where precise fit and a clean appearance matter, including visible sections of exhaust or performance builds.
Limitations: Plastic film should be removed before final assembly; improper removal can leave residues on edges.
Tellyouwin 3″ 5pcs — Tight Radius, Polished
Material: Premium 304 stainless steel, anti-rust, and resistant to heat, acids, and saltwater. Edges are mirror-polished for clean welds.
Finish and protection: Includes a protective bag to prevent damage during shipping and storage.
Best for: Builders who want polished pieces with dependable corrosion resistance and convenient packaging for easy storage.
Limitations: The 3″ OD is standard here; verify your exact bend requirements to ensure the 90° option matches your design.
Ticon Industries Titanium 3” Pie Cuts (5 PCS)
Specialty option: Titanium pie cuts delivered in 4.5° increments per side, totaling 9° per pie, for precise angular control in complex routes.
Finish and prep: Individually laser-cut and ultrasonically cleaned so they are ready to weld right out of the packaging. Titanium adds lightweight strength for weight-sensitive builds.
Best for: Projects requiring tight angular control and reduced weight, especially in performance or race-oriented fabrication.
Limitation: Titanium options can be more expensive and may require different welding considerations than standard 304 stainless steel.
Buying Guide
What should I consider when choosing a 3 inch pie cut?
- Material and corrosion resistance: Most options use 304 stainless steel for durability in heat and moisture. Titanium is lighter but costs more.
- Finish and edge quality: Polished edges reduce weld prep and improve appearance; deburred edges ensure cleaner welds and less snagging during installation.
- Radius and bend angle: A 90° bend is common for tight exhaust routes, but plan your layout to confirm the required angle and the number of pieces you’ll need.
- Welding requirements: Some sets are fully deburred and ready to weld, while others are raw sections that require fabricator skills for best results.
- Packaging and handling: Some pieces include protective films or bags to prevent damage in transit and storage.
How do you choose between 3 inch pie cuts for a project?
- If you need maximum flow with tight routing, prioritize tight-radius options with smooth internal geometry.
- For visible exhaust sections where appearance matters, prefer mirror-polished finishes and clean weld edges.
- For quick fabrication with less finishing work, choose deburred and ready-to-weld sets.
- Balance cost versus weight: Titanium variants offer strength-to-weight benefits but at a higher price point.
Installation and fabrication tips
- Plan the layout on paper or with app geometry before cutting to minimize waste and misalignment.
- Ensure proper edge preparation and compatibility with your welding method (MIG/TIG).
- Use protective films or bags during storage to protect polished surfaces and edges.
Quick reference FAQ
- What is a pie cut used for in exhaust fabrication? Pie cuts allow precise, curved segments to form custom exhaust routes with controlled bends.
- Are 3 inch pie cuts reusable after welding? Yes, but avoid excessive heat exposure that may alter shape or finish.
- Which material is best for corrosion resistance? 304 stainless steel offers strong corrosion resistance and heat tolerance for most automotive environments.
- Do I need to weld these pie cuts? Most products listed are unwelded or deburred sections designed to be welded by a skilled fabricator.
- Can I install these without professional tools? A TIG/MIG welder and basic fabrication tools are typically required to complete an exhaust assembly.
- Are there non-metallic alternatives for 3 inch bends? Pie cuts are typically metal; non-metal options exist but are uncommon for high-temperature exhaust use.
