Application: This 3 inch round muffler suits V8 performance exhaust systems running a larger 3 inch pipe, giving a longer 20 inch overall body for a fuller, more controlled tone than the shorter 3 inch hot dog muffler in the range.
-
Size/Spec Context: At 20 inches overall, this holds more internal volume than the 15 inch hot dog version at the same 3 inch pipe size, generally producing a deeper, less raspy note. Suits builds wanting a 3 inch flow path without the sharper tone of a shorter chambered or hot dog muffler.
-
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 to absorb sound while keeping flow open.
-
Fitment Note: Straight through in-line design suits single or dual exhaust systems running 3 inch pipe. Confirm your pipe diameter matches before ordering.
-
What to Pair With: Commonly paired with 3 inch mandrel bends, U-clamps and tail pipe outlets to complete the system.
-
Practical Buyer Tip: If comparing against the 15 inch hot dog muffler at the same 3 inch size, this longer 20 inch body will run quieter for the same pipe diameter.
