Borla F-250/F-350 SUPER DUTY '17-'19 6.2L V8 AT 2+4WD 4DR 3.5" x 8.5" EXTENSION PIPE FOR 148"WB (60691)

Replace the muffler behind the primary muffler in the "S-Type" system with this Polyphonic Harmonizer 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-controlled CNC manufacturing ensures an accurate fit.

Best of all, BORLA stands behind every connection pipe with a Million-Mile Warranty. Just what you'd expect from the world's most experienced (and most winning) exhaust brand.

Features:

• Made from aircraft grade, austenitic stainless steel
• Can be polished to a mirror-like finish
