DESCRIPTION
Product Overview
-
While upgrading to a 4" exhaust system significantly drops EGTs and increases flow, the standard 4" tailpipe can still look small and unfinished under large, lifted heavy-duty trucks.
- This 4-to-6 inch polished exhaust tip provides the ultimate finishing touch. Acting like a massive natural megaphone, it amplifies your diesel’s exhaust notes into a much deeper, authoritative rumble while giving your truck a aggressive, heavy-duty rear profile.
Key Features
- High-Temp Black Finish: Coated in a premium, heat-resistant black finish that resists chipping, peeling, and road salt corrosion while effortlessly masking ugly diesel soot.
- Aggressive 6" Megaphone Blast: Converts your 4" tailpipe into a massive 6" flared opening, naturally deepening your exhaust note for a throatier, deeper tone.
- Sleek Slant-Cut & Rolled Edge: Features an angled slant-cut profile to seamlessly align with your truck's quarter panel and a thick rolled edge for a muscular, premium look.
- Integrated Drainage Hole: Engineered with a discreet bottom weep hole to quickly drain trapped water, preventing internal moisture buildup and rust.
FAQ
Q: How do I clean and maintain the black finish?
A: The black coating is great at hiding black diesel soot. Simply rinse it with clean soap and water when washing your truck. Avoid using harsh steel wool or abrasive chrome polishes.
Q: Will jumping from a 4" pipe to a 6" tip affect my engine's backpressure?
A: No. The tip is located at the very end of your exhaust system. Expanding the tip only alters the acoustics (sound depth) and aesthetics; it has zero impact on engine backpressure or turbo performance.
Q: What is the main difference between the 4-6-12" and 4-6-15" versions?
A: The difference is purely visual and fitment-based. Both feature a 4" inlet and a 6" outlet. The 15" version provides an extra 3" of length, allowing it to extend further past the bedside or tuck deeper under the truck to hide the transition from the smaller 4" pipe.
Q: Can I install these 4-to-6 inch tips on a dual-exit exhaust system?
A: Yes, but check the spacing. If your truck has a dual exhaust setup (one on each side), running dual 6-inch tips creates an incredibly aggressive look. Just ensure the distance between your twin tailpipes and the bumper allows enough room for two wide 6-inch outlets without them touching.
