FITMENT

• Inlet Diameter: 4" ID (Internal Diameter) - Slips over 4" OD pipe; Outlet Diameter: 6" OD (Outer Diameter); Overall Length: 12".

• Perfect for upgraded Ford Powerstroke, Chevy GMC Duramax, and Dodge Ram diesel trucks running aftermarket 4" exhaust systems.

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

• Premium Polished Stainless Steel: Crafted from high-grade stainless steel to resist rust, flaking, and discoloration caused by corrosive exhaust gases and harsh winter road salt.
• 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 will expanding from 4" to 6" affect my exhaust note?

A: It acts like a megaphone. It naturally deepens the sound, transforming high-pitched rasp into a much lower, throatier rumble without drastically increasing raw volume.

Q: Will the massive 6-inch outlet clear my rear bumper or quarter panel?

A: Usually yes, but you should check clearance. Because a 6" tip is significantly wider than a standard 4" pipe, ensure you have at least 1 to 2 inches of clearance around your current tailpipe so the new flared tip doesn't vibrate against your bumper or body paint.

Q: How easily does this polished finish show diesel soot or black smoke?

A: The mirror-polished finish will show black carbon and diesel soot quickly if your truck is tuned or lacks a DPF. If you don't want to wipe down the polished stainless steel after every drive, we highly recommend choosing our High-Temp Black Coated version instead.

Q: Will jumping from a 4" pipe to a 6" tip affect my engine's backpressure or turbo spool?

A: No. The tip is located at the very end of your exhaust system, way past the turbo and downpipe. Expanding the very tip of the tailpipe only alters the acoustics (sound depth) and aesthetics; it has zero impact on engine backpressure, torque, or turbo performance.
