FAQ
What is the difference between this kit and the standard 3" exhaust builder kit (25-1033)?
The key difference is the construction method. The standard kit (25-1033) uses slip-fit construction with band clamps — sections slide together and are secured with clamps, making it easier to position and adjust before final installation. The Fabricator Edition uses weld-in construction with flared ends — designed for builders who plan to tack and weld everything permanently in place for a cleaner, more finished result.
Does this kit require welding?
Yes. This is a weld-in kit and requires welding for installation. It is not a slip-fit or clamp-on system.
What size tubing is included?
All tubing is 3" diameter, mandrel bent for consistent flow throughout.
Is this kit designed for a specific vehicle or header?
No. This is a universal build-your-own kit and is not designed for use with any specific Speed Engineering header or pipe product. It is intended for custom exhaust fabrication on any application.
