Application: This 2.5 inch round muffler suits V8 and six cylinder performance exhaust systems running a 2-1/2 inch pipe, offering a longer 20 inch overall body for a deeper, more restrained tone than the shorter hot dog style mufflers in the range.
-
Size/Spec Context: At 20 inches overall length, this round muffler gives more internal volume than the 15 inch hot dog mufflers, which generally produces a quieter, less raspy tone while keeping the same 2.5 inch flow path. Suits builds where sound level needs to stay closer to street legal.
-
Construction Note: Manufactured from heavy gauge T-409 stainless steel for long-term corrosion resistance, with a perforated inner pipe and glass fibre acoustic packing material to absorb sound without excessive restriction.
-
Fitment Note: Straight through in-line design suits single or dual exhaust systems running 2.5 inch pipe. Confirm your pipe diameter matches before ordering.
-
What to Pair With: Commonly paired with 2.5 inch mandrel bends, U-clamps and tail pipe outlets to complete the system.
-
Practical Buyer Tip: If you are chasing a deeper, quieter tone than the hot dog style mufflers, this longer round body is the better pick for the same 2.5 inch pipe diameter.
