Running Speed Engineering longtube headers on your F-150 and want a true dual crossover instead of a single-outlet Y-pipe? This X-pipe kit keeps both exhaust banks separate with a cast X-pipe crossover section for improved exhaust pulse balancing and a deeper, more aggressive tone. Built from 3" mandrel bent 304 natural stainless steel with TIG-welded construction and 3" stainless band clamps included. An optional wideband O₂ bung is available for tuning applications.
⚠️ Important: This X-pipe is designed and tested only with Speed Engineering longtube headers. It is not designed to work with factory exhaust manifold equipment.

Frequently Asked Questions:
Q: What is the difference between this X-pipe and the Speed Engineering Y-pipe (25-1170) for the F-150?
The Y-pipe merges both exhaust banks into a single outlet for connection to a single cat-back. This true dual X-pipe keeps both banks separate with a cast crossover section for improved exhaust pulse balancing and a more aggressive tone. Choose the Y-pipe for a single cat-back setup; choose the X-pipe for true dual exhaust character.
Q: Will this X-pipe work with factory exhaust manifolds?
No. This X-pipe is designed and tested only with Speed Engineering longtube headers. It is not designed to work with factory exhaust manifold equipment.
Q: Is a wideband O₂ bung included?
An optional wideband O₂ bung is available for wideband sensor placement for tuning applications.
Q: What is the X-pipe section made from?
The X-pipe crossover section is cast for durability and precision, paired with mandrel bent 3" 304 natural stainless steel tubing throughout the rest of the system.
Q: What material is this X-pipe made from?
304 natural stainless steel with mandrel-bent tubing and TIG-welded construction. 3" stainless band clamps are included.
