This universal Borla X-pipe is selected by exact manufacturer part number 621104. Confirm every inlet, outlet, body, offset, clearance, finish, and fabrication requirement against the Borla drawing before ordering.
Key Features
- Precision CNC Manufacturing: Computer-controlled fabrication ensures exact dimensions: 3.21in inlet centerline, 3.45in outlet centerline, 27.63in overall length and 45-degree ends.
- T-304 Stainless Steel: Heavy-duty construction resists corrosion and withstands extreme heat for long-term reliability in demanding conditions.
- Mandrel-Bent Design: Ultra-smooth interior bends maintain consistent diameter for unrestricted exhaust flow and peak horsepower gains.
- X-Pipe Configuration: Balances exhaust pulses between banks to reduce backpressure, sharpen throttle response and refine exhaust note.
- Leaders in stainless steel exhaust design since pioneering systems for classics like Rolls-Royce and Ferrari.
- Focus on mandrel-bent flow and T-304 materials sets the standard for performance exhaust fabrication.

Frequently Asked Questions
How do I confirm this universal Borla part will fit?
Match the inlet and outlet diameter, body dimensions, flow direction, offset or center layout, available clearance, material, finish, and required fabrication to the exact Borla drawing before ordering.
Will this change require an engine tune?
A cat-back, axle-back, tip, muffler, or post-catalyst component usually does not require tuning, but confirm the exact application, emissions configuration, oxygen-sensor locations, and local requirements before installation.
What should I inspect before installation?
Check the shipping carton and components against the exact part number, then inspect clamps, hangers, gaskets, mating flanges, clearances, tip alignment, and required reused factory hardware before removing the original exhaust.
Installation Instructions
Follow the current Borla instructions and vehicle service information for this exact part number. Let the exhaust cool, support the vehicle safely, compare all parts before removal, protect sensors and wiring, use the specified clamps and torque values, align all joints and tips without preload, confirm body and suspension clearance, check for leaks, and retorque after the first heat cycles. Professional installation is recommended.

Explore standalone fabrication components, resonator replacement assemblies, and catted connecting pipes by exact application, connection size, and exhaust configuration. What an Exhaust X-Pipe Does An X-pipe connects the two paths of a dual exhaust through a crossover, allowing exhaust pulses from both sides to interact. Its design can influence exhaust flow and sound, but the result depends on the engine, headers, catalytic converters, mufflers, and overall system layout. An X-pipe is not automatically a muffler, resonator, or complete exhaust system. Some products replace a factory sound-control section, while others connect specific headers to the remaining exhaust. Choose the component for its intended position and function. Vehicle-S...
