- Verify your system’s muffler length and 5" ID connections before ordering.
FAQ
Will the MDA531 fit my truck?It’s universal for 5" systems with a 31" muffler section, but it is not intended for 6.4L Ford, Chevy LMM, or 6.6L Dodge. Measure your existing section to confirm.
What’s the difference between Armor Lite and Armor Plus?Armor Lite is aluminized steel (great value). Armor Plus is T409 stainless (better corrosion resistance). See the stainless alternative MDS9531.
Is welding required?Most installs use band clamps or welding. For best results, mock-up first, then weld or clamp as appropriate for your system.
Does this come with clamps?No. Reuse existing 5" clamps or source MBRP 5" hardware. (Clamps sold separately.)
