JBA 65-73 Ford Mustang 351W 409SS H-Pipe

If you're looking to get more out of your 1964-1973 Ford Mustang's 351W engine, especially if you've already upgraded your headers, this JBA H-pipe is a solid choice. It's designed to replace the factory mid-pipe, opening up the exhaust flow to help your engine breathe easier. This means you can expect a noticeable bump in performance and a deeper, more aggressive exhaust note.

This H-pipe is constructed from 409 series stainless steel tubing, which is well-built and resists corrosion, especially when paired with JBA's stainless steel headers. The tubing is mandrel bent, meaning it maintains its diameter through the bends for unrestricted exhaust gas flow. It also includes O2 sensor provisions where needed and factory-style hangers for a straightforward installation. The hand-polished finish gives it a custom look under your Mustang.

Keep in mind that this H-pipe is not street legal in California or states that follow California emissions standards due to its lack of catalytic converters. It's intended for off-road or competition use only.
