Product Description
High-flow 5-inch universal muffler built in T409 stainless. The MBRP GP290022 uses a straight-through, louvered core to keep backpressure low while taking the edge off exhaust bark on big 5" systems. It’s a durable, budget-friendly stainless option sized to drop into most 5" diesel exhaust layouts with ~31" of straight section available.

FAQ
Will this fit my truck?It’s universal for any 5" system with about 31" of straight pipe available. Measure your available straight section and confirm 5" connections before ordering.
How loud is it compared to a straight pipe?It reduces harshness vs. a straight pipe while keeping flow strong thanks to the straight-through louvered core. For the quietest 5" option, see the Quiet Tone alternatives above.
Is T409 stainless good for winter/salty roads?T409 offers strong durability and value. For maximum corrosion resistance, frequent rinsing is recommended; T304 is even more corrosion-resistant but usually costs more.
Clamp or weld?Either works. Welding gives a permanent seal; quality 5" band clamps make future service easier.
What if I want quieter?Choose the Quiet Tone versions (M2220A aluminized or M2220S stainless).
