Product Description
Overview
MBRP’s MDA30 is a universal 4-inch muffler bypass (muffler delete) pipe from the Armor Lite (aluminized steel) series. It replaces a 30-inch muffler section to maximize flow and sharpen exhaust tone while keeping cost and weight down.

Fitment Details

FAQ
Will the MDA30 fit my truck?Measure your muffler section: this pipe is 30" overall with 4" connections. It’s universal for most 4" aftermarket diesel systems; OE-specific systems (like some 6.4L Ford and LMM Duramax layouts) may require model-specific parts.
Is hardware included?
Clamps/hangers are typically reused from your system; purchase new 4" clamps as needed (sold separately in our exhaust hardware sections).
How loud is a muffler bypass?
Louder and more aggressive than a muffler. If you want performance with some refinement, consider the MBRP GP015 high-flow muffler or Quiet-Tone M1004A/M1004S listed above.
Armor Lite vs. Armor Plus/XR?
Armor Lite is aluminized steel for strong value. Stainless options (Armor Plus/XR) offer increased corrosion resistance at a higher price.
