MBRP Exhaust vs. Stock: Is a Performance Exhaust Worth It for Your Truck in Austin?
Share
Technical Comparison Overview
Stock exhaust systems prioritize cost and sound suppression. MBRP exhaust systems prioritize exhaust flow and material durability. This document compares technical specifications and performance data for truck owners in Austin and nationwide.
| Feature | Stock Exhaust | MBRP Exhaust |
|---|---|---|
| Piping Type | Press-bent | Mandrel-bent |
| Material | Low-grade steel / Aluminized | Aluminized, T409, or T304 Stainless |
| Muffler Design | Baffled / Restrictive | Straight-through / High-flow |
| Sound Level | 1–2 (Quiet) | 3–10 (Variable) |
| Backpressure | High | Low |
Exhaust Flow and Mandrel Bending
Stock exhausts use press-bending. Press-bending creates restrictions at every curve. Mandrel-bending maintains a constant diameter throughout the pipe. MBRP uses mandrel-bent tubing. This reduces turbulence. Reduced turbulence lowers backpressure. Lower backpressure allows the engine to evacuate gases faster.

Performance Data: Horsepower and Torque
Data confirms performance increases when replacing stock systems with MBRP.
- Horsepower Gains: Typical increases range from 5 to 18 horsepower.
- Torque Gains: Increases range from 10 to 28 lb-ft.
- Throttle Response: Improved response due to faster turbo spool-up in diesel engines.
- Fuel Efficiency: Documented gains of 1–2 miles per gallon in specific cruise conditions.
- EGT Reduction: Diesel applications see Exhaust Gas Temperature (EGT) drops of up to 200°F.
Lower EGTs prevent turbocharger wear. This is critical for heavy towing in high-temperature environments like Austin, Texas.
Material Selection and Durability
Climate dictates material choice. Austin has high heat and humidity.
Aluminized Steel (Armor Lite)
- Composition: Mild steel with aluminum-silicon coating.
- Application: Dry climates.
- Pros: Lowest cost. High heat resistance.
- Cons: Susceptible to corrosion if the coating is scratched.
T409 Stainless Steel (Armor Plus)
- Composition: 11% chromium.
- Application: Most truck environments.
- Pros: High durability. Moderate cost.
- Cons: Develops surface oxidation (red/brown tint). Does not rust through.
T304 Stainless Steel (Armor Pro)
- Composition: 18% chromium, 8% nickel.
- Application: Coastal areas or high-salt environments.
- Pros: Highest corrosion resistance. Retains finish.
- Cons: Highest cost.
DIY Customs Store stocks all material grades for nationwide shipping.

Sound Profile Configurations
MBRP provides three primary sound levels to replace stock configurations.
1. Tour Profile
- Characteristics: Minimal volume increase over stock.
- Technology: High-volume mufflers with advanced packing.
- Use Case: Daily driving. Zero cabin drone.
2. Street Profile
- Characteristics: Aggressive under acceleration. Quiet at cruise.
- Technology: Straight-through design with acoustic dampening.
- Use Case: Enthusiast drivers.
3. Race Profile
- Characteristics: Maximum volume.
- Technology: No muffler or minimal resonator.
- Use Case: Off-road or track use.
Austin Local Environmental Factors
Austin truck owners face specific conditions.
- Temperature: Average summer highs exceed 95°F. High heat increases exhaust component expansion. MBRP uses heavy-duty hangers to manage thermal expansion.
- Humidity: Average humidity in Austin is 67%. This accelerates oxidation on stock aluminized systems. T409 or T304 stainless steel is recommended for longevity.
- Terrain: Hilly areas around the Colorado River require frequent downshifting. Performance exhaust reduces backpressure during high-RPM climbs.

Installation Requirements and Process
MBRP systems are bolt-on. No welding is required.
Required Tools
- Socket set (10mm to 19mm)
- Wrench set
- Penetrating oil (WD-40 or PB Blaster)
- Exhaust hanger removal tool
- Safety glasses
Installation Steps
- Preparation: Apply penetrating oil to all factory bolts and hangers.
- Removal: Unbolt the stock system at the flange or clamp point. Remove from rubber hangers.
- Initial Fit: Slide the MBRP front pipe into position. Secure loosely with provided clamps.
- Muffler and Tailpipe: Install the muffler followed by the tailpipe sections.
- Alignment: Adjust the tip for clearance from the body and bumper.
- Torque: Tighten all clamps to manufacturer specifications (typically 45-60 lb-ft).
DIY Customs Store employs MECP certified professionals to provide technical support during the installation process.
