Stainless Bros: Redefining Exhaust Fabrication Excellence

As a subsidiary of Ticon Industries, Stainless Bros has emerged as the premier supplier of professional-grade stainless steel exhaust fabrication components for builders, fabricators, and performance enthusiasts who demand uncompromising quality. Founded in the early 2000s and based in Texas, Stainless Bros controls every aspect of manufacturing—from the elemental composition of raw stainless steel to final quality control inspections—ensuring consistent excellence across their entire product lineup.

The Fabricator's Ultimate Resource

Unlike companies producing complete bolt-on exhaust systems, Stainless Bros specializes exclusively in premium fabrication components that empower professional shops and DIY builders to create custom exhaust solutions tailored to specific applications. Their comprehensive catalog serves turbo builds, naturally aspirated performance systems, diesel truck upgrades, import tuner projects, domestic muscle applications, and competition race vehicles.

Premium Stainless Steel Materials

Stainless Bros offers components in both SS304 and SS321 stainless steel grades. SS304 provides excellent corrosion resistance and weldability for most exhaust applications, while SS321 adds titanium stabilization for superior high-temperature performance in extreme turbo and racing environments. Every component utilizes 16-gauge (.065" wall thickness) construction for the ideal balance of strength, weight, and thermal management.

Mandrel Bent Tubing Excellence

At the core of their product line are precision CNC mandrel bends available in sizes from 1.5" through 5" diameter. Unlike compression bending that crushes and distorts tubing, mandrel bending maintains consistent internal diameter throughout the entire bend radius. This eliminates flow restrictions, hot spots, and turbulence that rob power and create back pressure.

Available bend angles include 15°, 30°, 45°, 60°, 90°, 180°, and specialized UJ (U-Joint) configurations. Both tight radius (1.0D) and loose radius (1.5D) options accommodate different clearance requirements and packaging constraints. Bends come with or without leg lengths, providing maximum flexibility for header collectors, downpipes, mid-pipes, and complete turbo-back systems.

Every mandrel bend features laser-cut ends for perfect mating surfaces, hand-finished to a fine 180-grit brushed appearance, and ultrasonic cleaning to ensure a ready-to-weld surface straight from the package. This attention to detail saves fabricators countless hours in prep work.

Comprehensive Turbo Components

For turbocharged applications, Stainless Bros offers an extensive selection of turbo-specific flanges including inlet flanges for popular turbocharger models (BorgWarner S200/S300/S400 series, Garrett GT series, Precision Turbo PTE configurations), outlet flanges in both traditional bolt patterns and v-band configurations, and wastegate flanges for TiAL, Turbosmart, and other popular external wastegate brands.

Their Sequence Merge Collectors utilize advanced CFD-designed merge technology that optimizes exhaust pulse timing and scavenging effects for maximum power extraction in multi-cylinder turbo manifold builds.

V-Band Clamp Systems

Professional fabricators rely on Stainless Bros' heavy-duty v-band clamp assemblies for secure, leak-free connections that enable quick disassembly. Available from 2.5" through 5" diameters, these CNC-machined 304 stainless flanges pair perfectly with their proprietary clamps designed for proper sealing characteristics and clamping force distribution.

Quick Release V-Band Clamps feature cam-lever mechanisms for tool-free installation and removal—essential for competition vehicles requiring frequent turbo changes, exhaust modifications, or inspection access. Standard v-band clamps provide maximum clamping force for permanent installations.

Pie Cuts and Transitions

Custom exhaust routing demands precise angle adjustments. Stainless Bros manufactures both tight radius and loose radius pie cuts in 4.5° and 7.5° increments, allowing fabricators to create smooth bends at any angle by combining multiple sections. This modular approach enables complex routing around frame rails, suspension components, and drivetrain obstacles.

Transition Reducers in cone-style configurations provide smooth diameter changes from 1.5" up to 5", maintaining velocity and minimizing turbulence when connecting components of different sizes.

Muffler and Resonator Options

For sound control without sacrificing performance, Stainless Bros offers several muffler configurations:

Round Ultra-Light Mufflers utilize straight-through perforated core design with high-temperature fiberglass packing for minimal restriction and weight savings—ideal for track-focused builds where every pound matters.

Oval Mufflers pack additional sound-absorbing material into a low-profile design, delivering quieter operation with an OEM-plus aesthetic. Available in standard and thin-profile versions to fit tight clearance situations.

Bottle/Bullet/Oval Resonators provide drone reduction when placed strategically in exhaust systems, particularly effective at eliminating cabin resonance in the 1,800-3,000 RPM cruise range. Available in 2.5", 3.0", and 3.5" sizes with various body lengths.

Professional Fabrication Accessories

Beyond primary exhaust components, Stainless Bros supplies the complete range of professional fabrication essentials:

  • Straight Tubing in 2-foot and 4-foot lengths across all diameters
  • Flex Joints for vibration isolation and thermal expansion management
  • Slip Joint Connectors for serviceable connections
  • O2 Sensor Bungs and exhaust temperature probe bungs
  • Exhaust Hangers and mounting hardware
  • Silicone Couplers and high-pressure Mikalor Supra band clamps
  • Welding Supplies including ER308 and ER347 TIG filler wire optimized for stainless fabrication

Vehicle-Specific Flanges

Stainless Bros manufactures precision exhaust flanges for popular platforms including Porsche 996/997 Turbo, Audi R8/Lamborghini Huracan V10, BMW S-series engines, and other European exotic applications requiring exact OEM fitment specifications.

Quality Control Standards

Every component undergoes rigorous inspection ensuring dimensional accuracy, weld integrity, and surface finish quality. Stainless Bros' commitment to controlling raw material chemistry ensures consistent chemical composition across production runs—critical for TIG welding characteristics and long-term corrosion resistance.

Applications Across the Performance Spectrum

Import Tuner Builds: Complete turbo manifold kits for Honda K-series, Subaru EJ/FA platforms, Mitsubishi 4G63, Nissan SR20/RB26, Toyota 2JZ applications utilizing tight-radius mandrel bends and v-band turbo flanges.

Domestic Muscle: LS-swap exhaust systems, Coyote headers, HEMI turbo builds requiring larger 3.5" to 5" diameter components for high-horsepower naturally aspirated or boosted applications.

Diesel Performance: Heavy-duty 4" and 5" exhaust components for Cummins, Duramax, and Power Stroke diesel truck builds, turbo upgrades, and DPF-delete systems where legally permitted.

Competition Racing: Ultra-lightweight components for drag racing, road racing, time attack, and drift applications where rules allow custom fabrication.

Exotic Upgrades: Premium aftermarket exhaust systems for European supercars requiring showroom-quality welds and finishes.
