FAQs

Aluminized vs. stainless — which should I choose?
Aluminized offers excellent value and everyday durability; stainless maximizes corrosion resistance in harsh climates. Sound and flow are comparable in like-for-like systems.
Will this system drone?
Our bend geometry and muffler selections minimize cabin drone at highway speeds while preserving a confident diesel tone.
Is it truly bolt-on?
Yes—OE locations, contour-bent hangers, and Perfect Fit Lap Joint Exhaust Band clamps simplify install with hand tools. Remember to re-torque clamps after 100–150 miles.
