TitanFlow Titanium Tube Set (2″, 2.5″, 3″ OD)
The TitanFlow set features Grade 1 pure titanium with wall thickness around 1mm. Available in multiple diameters (2″, 2.5″, 3″ OD) and lengths of about 2 or 4 feet, these tubes offer strong, corrosion-resistant performance for custom exhaust fabrication. Suitable for weight-conscious builds where titanium’s high strength-to-weight ratio is beneficial.
- Material: Grade 1 Pure Titanium
- Lengths: ~2 ft (60 cm) or 4 ft (120 cm)
- Diameters: 2″ (51 mm), 2.5″ (63 mm), 3″ (76 mm) OD
- Wall thickness: ~1 mm
TitanFlow Titanium Tube (2″, 2.5″, 3″ OD) — 2 ft / 4 ft
This version mirrors the first TitanFlow option with emphasis on the 2 ft and 4 ft lengths and an emphasis on pure titanium structure. The combination of diameters makes it suitable for bespoke resonator placements, mid-pipe segments, or header extensions in titanium builds. The consistent 1 mm wall enhances rigidity while keeping weight down.
- Grade 1 Titanium
- 2 ft or 4 ft lengths
- 2″, 2.5″, 3″ OD
- 1 mm wall
TitanFlow Titanium Tube 3″ OD (2 ft / 4 ft)
Designed for higher-diameter runs, this Titanium Tube features a 3″ OD option and the same 2 ft or 4 ft length choices, providing versatility for larger-diameter exhaust sections. Titanium’s heat resistance supports performance applications where heat management is critical, such as high-output builds or race-inspired setups.
- Grade 1 Titanium
- 2 ft or 4 ft lengths
- 3″ OD
- 1 mm wall
DNA Motoring ZTL-25SS Stainless Kit — 2.5 Inch
DNA Motoring offers a comprehensive 2.5″ stainless mandrel-bend kit, including straight pipes and various bends. The kit is designed for universal fit, simplifying fabrication for DIY enthusiasts who prefer stainless steel over titanium. It provides options for 4 pieces of 48″ straight pipes and multiple bend configurations to create complex exhaust routes.
- 18-Gauge piping walls
- Inlet/outlet: 2.5″ OD
- Includes straight, 90°, 45°, and 180° bends
- Universal fit for DIY fabrication
2.5 Inch Stainless Steel Tubing — 17.3″ Straight
This 2.5″ stainless steel straight tube offers compact length for short-run sections or as a matching component in mixed-material builds. Its 2.5″ inner diameter supports compatibility with a wide range of exhaust components, while stainless construction brings corrosion resistance and durability for daily-use or performance-oriented applications.
- Exterior-ready stainless steel tubing
- 2.5″ inner diameter reference
- 17.3″ straight segment
JY Performance 2.5 Inch Stainless Tubing
JY Performance provides a 2.5″ OD stainless steel tubing option with a length of 47.3 inches, suitable as a primary straight section or for extending a system. The T304 stainless steel construction offers corrosion resistance and durability for a wide range of exhaust fabrication tasks.
- T304 Stainless Steel
- 2.5″ OD
- Approx. 47.3″ length
Buying Guide: Key Purchase Considerations
- Material choice: Titanium delivers high strength and light weight but at a higher cost and specialized handling; stainless steel offers robust durability, easier fabrication, and broad accessory compatibility.
- Wall thickness: Typical titanium options feature around 1 mm walls; thicker walls provide greater rigidity but add weight. Match wall thickness to your performance goals and budget.
- Diameter and length: Ensure the chosen tubing diameter aligns with your headers, mid-pipe, or resonator design. Long runs may require multiple pieces with butt or slip-fit connections.
- Mandrel bends vs. crush bends: Mandrel-bent tubing preserves cross-sectional area through bends for better flow; avoid crush-bent sections that can restrict exhaust flow and create hotspots.
- Installation compatibility: Check that connectors, clamps, and flanges match your tubing diameter and wall thickness. Some kits include a full set of bends for DIY ease.
- Corrosion resistance and heat tolerance: Titanium excels in heat and corrosion resistance, valuable in high-heat environments. Stainless steel offers cost efficiency with strong durability for a wide range of conditions.
- Project scope: For lightweight, performance-focused builds, titanium is appealing; for broader DIY enthusiasts or budget-conscious projects, stainless options provide reliable performance with easier sourcing.
- Availability and sourcing: Titanium products may come with longer lead times and sourced from specialized suppliers. Stainless options are widely available and economical.
