Building a fully custom exhaust system and planning to weld everything in place? Speed Engineering's 3" Fabricator Edition exhaust builder kit is the step up from the standard slip-fit builder kit — an assortment of mandrel bent 304 natural stainless tubing with flared ends for tight, weld-ready fitment.
Note: This is a universal weld-in build-your-own kit and is not designed for use with any specific Speed Engineering header or pipe product. Welding required.
Features:
- 3" Mandrel Bent Tubing — Consistent diameter throughout for maximum exhaust flow
- Flared Ends — Sections fit together cleanly for tack and finish welding
- Assortment of Bent Tubing — Multiple bends and sections for flexible custom routing
- 304 Natural Stainless Steel Construction — Corrosion resistant and built to last
- Universal Fit — For custom exhaust fabrication on any application
Frequently Asked Questions:
Q: 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.
Q: 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.
Q: What size tubing is included? All tubing is 3" diameter, mandrel bent for consistent flow throughout.
Q: 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.
Q: What material is this kit made from? 304 natural stainless steel with mandrel-bent tubing and TIG-welded construction. Flared ends are included on all sections for weld-ready fitment.
