Custom Exhaust Fabrication for a Race Boat Build in St James MO

This one was a serious build. We were working with a turbocharged race boat running a big-block setup, and the customer needed the exhaust side completely redone to make room for a new pro-charger configuration. Old wrapped pipes out. Clean stainless fabrication in.

Here's what we were dealing with on the front end - four exhaust tubes wrapped in heat wrap that had seen better days. The wrap was fraying, the pipes underneath were tired, and none of it was going to work with the new forced induction setup being planned. Starting fresh was the only real option.

We fabbed up a fully custom stainless steel header merge collector from scratch. The mirror-polished finish isn't just for looks - stainless holds up against the heat cycles a forced induction race application throws at it. The bends are tight and intentional, designed to fit the specific geometry of this engine bay without robbing flow.

Getting the routing right in a boat engine bay is a different challenge compared to a car. Space is tight, angles are awkward, and everything has to clear components that don't move. We took our time laying out the collector and the primary pipes so the install would drop right in without interference issues.
