Frequently Asked Questions

Does the S7115AL fit the Dodge Challenger SRT or Hellcat?
No. The MBRP S7115AL is engineered specifically for the 5.7L V8 HEMI R/T and R/T Plus models for 2015-2016. It does not fit 6.2L or 6.4L HEMI applications.

How loud is the S7115AL on a 2015-2016 Challenger R/T?
The S7115AL uses the Street profile with tuned resonators that produce an aggressive note during acceleration and a moderate, refined tone at idle and highway cruise. It is louder than stock but not raspy or droning.

Is the MBRP S7115AL a direct bolt-on for my Challenger R/T?
Yes. The S7115AL is engineered for direct bolt-on fitment to the factory exhaust manifolds and reuses the stock rubber mounting hangers. No cutting, drilling, or welding is required.

Will installing the S7115AL affect my Challenger's emissions or require a tune?
The S7115AL is a cat-back exhaust, meaning it replaces only the section behind the catalytic converters. Catalytic converters remain in place, so emissions compliance is maintained. No ECU tune is required for installation.

How much power can I gain with the S7115AL on my Challenger 5.7L HEMI?
Reduced backpressure from the 3-inch mandrel-bent tubing and crossover X-pipe can contribute to measurable horsepower and torque improvements. Results vary by specific build and configuration.

What size are the exhaust tips on the S7115AL?
The system includes four 4-inch diameter polished stainless steel tips with a single wall design and an embossed MBRP logo.

How long does it take to install the MBRP S7115AL cat-back exhaust?
Installation typically takes 2 to 3 hours using basic hand tools. The system is designed for DIY installation and mounts in the factory hanger positions.

Does the MBRP S7115AL come with a warranty?
Yes. MBRP covers the S7115AL with a 3-year limited warranty against defects in materials and workmanship.

Installation Instructions

1. Safely lift and support the vehicle on jack stands. Allow the stock exhaust to cool completely.
2. Apply penetrating oil to all factory exhaust flange bolts and hangers. Allow to soak for 10 minutes.
3. Remove the factory exhaust from the rear of the catalytic converters rearward, unclipping from all rubber hangers.
4. Compare the MBRP S7115AL components to the factory parts for routing reference.
5. Begin installation at the catalytic converter connection point, hand-tightening the flange hardware.
6. Route the crossover X-pipe section into position, placing mounting clamps loosely.
7. Install the resonator mid-section and route tubing to the rear of the vehicle.
8. Mount quad tip section onto factory rubber hangers, ensuring proper positioning and equal tip protrusion.
9. Verify all four tips are even and the system clears all chassis components through full suspension travel.
10. Tighten all clamps and flange hardware to specification, working front to rear.
11. Start the engine and inspect for exhaust leaks at all connection points.
