Stainless Works TT3311 Tubing Transition 3" OD to 3" ID 11" OAL 304 SS USA Pair

Vehicle Fitment

• Universal - fits any exhaust system using 3" OD tubing that requires a slip-fit connection to 3" ID piping

Fitment Notes

• 3" OD inlet slides over existing 3" OD tubing; 3" ID outlet accepts 3" OD tubing from the downstream section
• 11" overall length provides extended overlap for secure clamping or welding in custom exhaust fabrication builds
• Longer than the standard 6" Stainless Works tubing transitions - designed for applications requiring additional clearance or overlap
• Can be welded or clamped into place depending on application
• Sold as a pair - includes two transition pieces

Features

• 11" overall length provides generous overlap for a secure, rattle-free connection in tight or long-reach applications
• 3" OD-to-3" ID slip-fit design allows tubing to slide together cleanly without reducing the exhaust bore diameter
• Fabricated from corrosion-resistant 304 stainless steel for long-term durability under sustained exhaust heat
• Smooth inner bore maintains full exhaust flow without restriction or turbulence at the connection point
• Compatible with welding or clamping - accepts standard 3" exhaust clamps for tool-free installation in most applications
• Proudly made in the USA and backed by Stainless Works' Limited Lifetime Warranty

Product Description

The Stainless Works TT3311 is a universal 304 stainless steel tubing transition designed to create a clean slip-fit connection between two sections of 3" exhaust tubing. With a 3" OD inlet that slides over existing 3" OD pipe and a 3" ID outlet that accepts standard 3" OD downstream tubing, this transition maintains the full 3" exhaust bore without any diameter reduction or restriction. At 11" overall length, it provides significantly more overlap than the standard 6" Stainless Works transition - making it well suited for custom fabrication applications where additional reach, clearance, or a longer clamping surface is needed.

Sold as a pair, these transitions are a practical solution for exhaust builders working on performance catback systems, header-back builds, or replacement exhaust work that uses 3" tubing throughout. They can be permanently welded into place or secured with a standard 3" exhaust clamp depending on the build requirements. Built from 304 stainless steel and made in the USA, they're backed by Stainless Works' Limited Lifetime Warranty on materials and craftsmanship.
