Description
Overview
Build your system your way with the Flowmaster Exhaust Pipe, a straight length of 409 stainless steel designed for clean, professional exhaust fabrication. With a full 48.00 in. body length and no bend, this straight run gives fabricators and DIY builders the raw material needed to connect components, extend a run, or replace a worn section without compromising flow. It slots into Flowmaster’s broader family of exhaust and tail pipes engineered for 100% custom exhaust builds.
Measuring 2.50 in. (2-1/2 inch) in tubing diameter throughout, this pipe delivers a consistent primary and main piping diameter for smooth, unrestricted flow. The 16-gauge wall thickness and 409 stainless steel construction bring durability and corrosion resistance to the table, making it a smart choice for a lasting performance exhaust system rather than a quick patch.
Key Benefits
Whether you’re welding up a full performance exhaust from scratch or replacing a rusted tail pipe, a quality straight length is the backbone of the job. This Flowmaster exhaust pipe is graded as a High Performance automotive item, giving you a dependable foundation for exhaust pipes and exhaust parts that need to hold up to heat, road grime, and time. Pair it with mandrel bends to route your system exactly where it needs to go.

Part of a Full Custom Exhaust Line
Flowmaster’s exhaust accessories now include a full line of mandrel bends available in pipe diameters from 2.00 in. to 3.00 in. These stainless steel bends come in various radii and angles from 45 to 180 degrees to allow 100% custom exhaust fabrication. Combine this straight 2.50 in. pipe with the matching bends to route around axles, crossmembers, and floor pans while keeping a smooth, mandrel-quality flow path from front to tail pipe.
Fitment & Fabrication
Because this is a universal straight length rather than a vehicle-specific kit, it’s meant to be cut, positioned, and welded to suit your exact application. That flexibility makes it a favorite for anyone piecing together a custom exhaust or upgrading a section of their existing exhaust system. Please note this product carries a California Proposition 65 warning.
Choose the Flowmaster 2.50 in. exhaust pipe as the building block for your next performance exhaust project and enjoy stainless steel quality you can weld with confidence.
