Frequently Asked Questions
Q: Will this fit my 2015 Duramax?
A: If you have a 3" exhaust system, yes. This is a universal fit muffler — verify your pipe diameter is 3" before ordering. Center in/center out configuration.
Q: Does this come with clamps?
A: No, clamps are sold separately. We recommend 3" stainless steel band clamps for a secure, leak-free connection.
Q: How loud is this muffler?
A: This is a straight-through resonator design — it provides moderate sound reduction while maintaining a deep performance tone. Louder than a chambered muffler, quieter than a straight pipe.
Q: Is this stainless or aluminized?
A: 409 stainless steel — offers better corrosion resistance than aluminized steel at a more affordable price than 304 stainless.
Q: Can I use exhaust clamps instead of welding?
A: Yes, 3" stainless band clamps work well and allow for future removal if needed.
