Cobra has introduced an updated version of its original Tri-oval slip-on muffler. While the Tri-Oval was a hit from the start, the Tri-Oval II mufflers offer improvements in nearly every way. This is a significant upgrade while retaining many of the original design elements.

“The Tri-Oval really broke the design mold at a time when slipon mufflers all looked the same,” said Tim McCool, Cobra President. “We pushed the creative envelope a bit then, and continue to do so with our innovative designs to this day. The improved and reshaped Tri-Oval II is just the latest example of a great design matched with outstanding performance.”

The new Tri-Oval II shape begins with a four-inch round, single piece muffler body that gets ovalized at the rear by way of a specially designed tool built in house at Cobra Engineering. The redesigned chromed tips retain their unique dual-port outlet pattern, while a graceful scalloped edge forms the top line of the tip. Machined alluvial flutes highlight the interior inclines of the solid aluminum tips. The mufflers deliver in a multimodal fashion, moving from the graceful, machined shapes to the low feral growl barking from the mufflers. The louvered cores conduct that rich sound in part by the way each core merges into a formed Y-shaped collector inside the dual exit ports at the rear. It’s one of those valuable intersections between the visual and the aural. And it is the specific acoustic manipulation by that louvered core which gives the Tri-Oval II its distinctive yowl under acceleration and its gruff rumble on run down. It's a sound reminiscent of the original Tri-Oval muffler, but improved with a bit less rasp than before, and one that is deeper and fuller than the previous generation.

Said McCool, “we have made every attempt to make the Tri- Oval II the premier muffler in the business. From performance, to style to sound, it clearly is in a class by itself.”

Emissions Notice The state of California considers aftermarket exhaust systems to be legal replacement parts for non-catalyst equipped motorcycles and/or if slipon mufflers are installed downstream of the OEM catalysts. California does not allow the use of aftermarket systems that remove original equipment catalysts, (except for racing use only) unless the Air Resources Board has issued an Executive Order for that system. For California riders we offer Air Resources Board approved Fi2000R ARB units (ARB E.O. No.D-633-1). All other Fi2000 models are not legal for street use in California.
