Product Description
DIAMOND EYE 800465 is the 5" Big Dog Quiet Tone, a chambered, baffled universal diesel muffler built from aluminized steel. It reduces in-cab drone and harshness without choking flow—perfect for heavy-duty trucks that need a calmer tone on the highway and under tow.
FAQ: HOW QUIET IS THE BIG DOG?
Noticeably quieter than a straight-through race muffler or a delete pipe. The internal chambers focus on cutting drone while maintaining strong flow for tuned and towing builds.
FAQ: WILL THIS FIT MY TRUCK?
Yes—this is a universal muffler with 5" I.D. inlet and 5" I.D. outlet. Verify you have room for the 51" overall length (45" body) and confirm hanger locations before purchase.
FAQ: WHICH WAY DO I INSTALL IT?
It’s single-in / single-out. Align for clearance and weld or clamp into your 5" system per your preferred install method.
