Description
Overview
Build the custom system your project deserves with the Flowmaster U-Fit Dual Exhaust System Kit. This crossmember-back, universal package gives you the raw components to fabricate a complete mandrel-bent dual exhaust system on nearly any street rod, muscle car, or pickup. If you’ve been searching for a durable, build-it-your-way performance exhaust that puts the design in your hands, this Flowmaster kit is engineered to deliver.
Constructed entirely from 409S stainless steel, the kit combines corrosion resistance with the kind of long-term durability builders have longed for. The slip-fit design makes assembly and adjustment straightforward, letting you dial in the routing, angles, and length that suit your chassis before you commit to final welds.
What’s In The Kit
The kit includes twelve pieces of 2.50-inch diameter tubing in carefully selected bend configurations, giving you the flexibility to route both sides of a true dual system. Four additional 2.00-inch diameter components are supplied specifically for fabricating a crossover pipe, so you can tailor a balanced, custom exhaust exhaust pipe layout for your demanding vehicle project. Every piece is mandrel bent to preserve smooth interior diameter and consistent flow through each exhaust pipe.

Key Benefits
Whether you’re upgrading a classic muscle car, finishing a street rod, or building out a pickup, this kit gives you the freedom of a fully custom catback-style dual layout without hunting down individual bends. The 16-gauge pipe wall and stainless construction stand up to heat and the elements, making it a smart foundation for a lasting car exhaust system. Fabricators who want to shop for exhaust components that go together their way will appreciate the versatility here.
Fitment & Installation Notes
This is a universal kit designed for custom fabrication, so it adapts to a wide range of chassis rather than bolting to one specific application. The kit uses new hangers, which are not included, and a muffler is not included — allowing you to pair your preferred muffler and mounting hardware with the system. Because it’s CARB compliant with Emission Code 5, it’s suited for street-legal builds in applicable states. Please note the California Proposition 65 warning applies to this product.
For anyone comparing Flowmaster against a Borla exhaust, Corsa exhaust, MagnaFlow exhaust, or Walker exhaust, the U-Fit Dual kit stands apart by putting complete design control in your hands while delivering the durability of 409S stainless steel.
