New FlowMonster Chambered Mufflers from ... Flowmaster?

Posted by Andy McJannett on

Not just another Flowmaster knockoff!

FlowMonster mufflers actually come from ... Flowmaster?!

While there have been many ‘white box’ copies of the iconic chambered Flowmaster mufflers, many of suspect quality and durability, FlowMonster mufflers are the ONLY inexpensive chambered muffler made by Flowmaster!

Compared side by side, the FlowMonsters are identical to the Flowmaster (other than colour) in exterior dimensions, inlet and outlet locations as well as baffle placement for that awesome chambered muffler sound.

We even pulled some from the box and found them to have the same weight (9.6lbs for a 2-chamber) and .080” wall tubing thickness.

Why choose FlowMonster?  Price!

Regardless of size or configuration, they are all $49.95CDN+tax!

All One-Chamber & Two Chamber mufflers are the same low price of $49.95. And while Flowmasters used to be made in the USA, recent shipments have confirmed that they are now produced in China, as are FlowMonsters.
