Does this 4-inch dual exhaust kit fit 6.7 Powerstroke Cab & Chassis models?

No. Cab & Chassis models have narrower rear frame rails, different fuel tank placements, and altered rear suspension geometry compared to standard pickup beds (F-250 / F-350 Pickup). This kit is engineered specifically for standard pickup bed configurations.

Will I need to remove or relocate my factory spare tire for a dual exhaust setup?

Because this dual kit routes piping around both sides of the rear axle and differential, some wheelbases and bed configurations may require adjusting or removing the oversized factory spare tire to ensure proper clearance for the driver-side tailpipe.

Can I add a muffler to this 4-inch dual DPF delete exhaust system?

Yes. If you prefer reduced interior drone while retaining high-flow exhaust benefits, a straight-through 4-inch performance muffler can be welded or clamped into the intermediate section before the Y-pipe split.

Does this 4-inch downpipe-back kit require a custom tuner?

Yes. Removing the factory DPF alters backpressure and sensor readings. You must install a compatible off-road tuner to turn off regeneration cycles and clear Check Engine Lights (CEL).

Will installing a dual DPF delete exhaust improve my truck's fuel economy?

Eliminating the restrictive DPF stops active fuel-burning regeneration cycles. When paired with proper tuning, most 6.7 Powerstroke owners see a noticeable improvement in overall MPG.

How does deleting the DPF impact long-term engine reliability and routine maintenance?

Removing the DPF stops diesel fuel from diluting your engine oil during regen cycles, significantly boosting overall engine lifespan.

Single Exit vs. Dual Exit Exhaust Comparison

Comparison Dimension	4"Single Exit (Single Pipe)	4"Dual Exit (Dual Pipe Kit)
Exhaust Sound	Deep & Low Resonance. Single large-diameter pipes produce a lower frequency rumble with minimal drone.	Crisp & Loud. Splitting flow into two pipes increases sound frequency, producing a sharper, more aggressive tone at higher RPMs.
Visual Style	Rugged & Traditional. Single side-exit tailpipe for a clean OEM+ look.	Symmetrical & Aggressive. Dual exits deliver a muscular stance for 2016 f250 dual exhaust and f350 dual exhaust builds.
Fitment & Underbody	Simple Installation. Follows factory routing channels without interfering with spare tires.	Symmetrical Routing. Requires routing around axle and differential; may require spare tire adjustment on specific wheel bases.
Performance & EGT	Direct Flow. Excellent EGT reduction under heavy towing and high boost conditions.	Dispersed Flow. Optimizes low-to-mid range torque response for daily driving setups.
Cost & Complexity	Budget-friendly with fewer components.	Premium dual-pipe aesthetics with heavy-duty Y-pipe splitter hardware.

Exhaust System Buyer Guidelines

Choose Single Exit if: You regularly tow heavy loads, prefer a deep low-frequency tone without highway drone, and want a quick bolt-on setup that preserves full spare tire placement.
Choose Dual Exit if: You prioritize symmetrical rear styling for truck shows or daily street presence, want an aggressive exhaust note, and drive mostly unladen or city routes.

Installation Overview & Technical Notes

Estimated Installation Time: 2.5 – 4 Hours (Depending on rusted factory hardware and shop tools available)

Installation Difficulty:Moderate to Advanced

Key Installation Considerations:

Direct Bolt-On Design: Engineered to utilize factory mounting hanger locations without major frame welding.
Underbody Clearance: Dual tailpipe routing requires extra alignment around the rear axle, differential, brake lines, and spare tire location compared to a single-exit system.
Spare Tire Fitment: Depending on your truck's wheelbase and oversized aftermarket tire size, temporary lowering or removal of the spare tire during installation may be required for optimal tailpipe symmetry.
Tuning Requirement: Off-road race tuning is required immediately following installation to clear DPF regeneration codes and Check Engine Lights (CEL).

Professional installation by an experienced diesel performance technician is highly recommended.
