Replace the small muffler behind the primary muffler in the BORLA® S-Type system with Polyphonic Harmonizer 60680 to attain the ATAK® sound level (louder than S-Type). BORLA®'S Polyphonic Harmonizer Technology utilizes patented units that contain pipes of different diameters and lengths to create multiple exhaust notes that harmonize to deliver a clean, rich, full-bodied sound to the BORLA® mufflers. The mufflers then enhance this sound to the character and volume appropriate for our Touring, S-Type and ATAK® systems. Built from premium T-304 stainless steel, superior to T-400 series (such as 409), to give you the absolute best in performance and durability. Ultra-smooth mandrel bends ensure maximum flow & power, and precision computer numerical control (CNC) manufacturing ensures an accurate fit. Best of all, BORLA® stands behind every Polyphonic Harmonizer with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.This Part Fits:

The length is perfect. Nice and long.
Color: Yellow, Size: X-Large
These tanks are the perfect length. I love how they fit and feel. I bought these in 5 colors. Although, if you want to keep them long, I suggest hanging them to dry. Putting them in the dryer shrinks the length about 2 inches.

Great Tank Top
Color: White, Size: Large
I love this top. It fits snug and is comfortable. The length is perfect. I especially like the wide shoulder straps which hides my bra straps. I’ll order more of these in different colors.

Get it!!
Color: White, Size: Small
Great tank and definitely want to buy in more colors! Thick enough to not be see through but not to make you die of a heat stroke. Good cut and cute fit! Seems like it’ll last awhile! Perfect as a top or as an under layer if needed.
