Product Spotlight: Sequential 8-1 Headers by HDR Industries & Stainless Headers MFG. INC.
Let’s cut to the chase, because this definitely isn’t your grandpa’s set of rusty old manifolds. The HDR Sequential 8-1 Headers from Stainless Headers are a next-level, hand-crafted performance weapon for big-inch V-8s — purpose-built for jet boat and high-output marine applications — and they were one of the most talked-about exhaust systems as seen at PRI 2025.

Honda Header Shootout
When it comes to performance, there is one steadfast rule: All the good air that goes into making horsepower must eventually find its way out. This means that adding all the cool camshafts, intake manifolds and even superchargers to help improve airflow into the motor will be useless (okay, maybe not useless, but certainly much less effective) if the motor is not able to rid itself of the exhaust. Cork up a serious performance motor and watch it struggle and gag on its own exhaust fumes.
