*UPDATE KIT TO TWIN CAN SYSTEM*

Upgrade Your Existing Catch Can to the Twin Can System

Already running one of our original RXP Catch Can systems? This update kit brings your setup up to our latest 2026 redesign — the most effective blow-by filtration system we've ever built.

What's Included

• New mounting bracket
• 6 feet of hose
• Barb fitting
• New filtered CSS (Clean Side Separator) can with drain

Why We Redesigned It

Our original RXP Catch Can systems were the best on the market — but we made them even better. During boost, the original clean-side CSS would occasionally allow pressure to escape back toward the air filter box, leading to minor oil accumulation and odor over time. While this is normal factory behavior, we engineered a solution: a new 5-chamber Ultimate Catch Can System with an inline CSS that eliminates this issue entirely.

Vehicle-Specific Notes

• Ford EcoBoost owners (2015+): Your kit includes an adapter to retain the stock sensor location.
• GM owners: Your kit includes a tee for the valve covers, routing blow-by to the new CSS can instead of venting vapor near the throttle body.

You can order this CSS update kit on its own, or upgrade to the complete Twin Can System. Either way, your engine will thank you.
