Replace the small muffler behind the primary muffler in the Borla(r) S-Type system with Polyphonic Harmonizer 60680 to attain the ATAK(r) sound level (louder than S-Type). Borla(r) '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(r) mufflers. The mufflers then enhance this sound to the character and volume appropriate for our Touring, S-Type and ATAK(r) 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(r) 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:

Garbage
Size: 6FT*6FT, Color: Black
This product is absolute garbage! It literally took all day to put it together and if the air conditioning blows on it the wrong way than the whole thing top over and it falls apart.
It’s not made of quality material and is very flimsy. The only reason I’m not returning it is because it’s too difficult to put together and I don’t wanna spend that much time trying to take it apart. Do not buy this!
