I love Borla mufflers but these "Crate" mufflers are definitely a gimmick how can you tune it to a specific motor when there are so many variables
But they don't sound bad here on this 440
I have narrowed my personal choices down to 3 different mufflers and heres my list maybe it will help you in deciding
Borla XR-1 (No idea how the sound compares between oval and round case)
Guy in this vid gets on it around 3:30
Oval Case: 40943 & 40944 The 40943 is most likely louder than the 90944 because of the shorter case length
Round Case: 40085
Black Widow Exhaust Widow Makers
They have the same size specs as the Borla S Type Mufflers but 1/2 the cost and come in 3 inch Black Widow Exhaust - Products
