Kooks 1-3/4" to 1-7/8" Long Tube Headers W/ Catted X-Pipe
Add horsepower and torque that pairs with the throaty exhaust note to your 2014-2020 Mustang GT350 with a set of Kooks headers with catted x-pipe kit! Kooks builds all of its products to the highest standard, and these are quite possibly one of the best long-tube header systems you can buy for your S550 Mustang! As the stock exhaust on your Mustang ages, the catalytic converters can become clogged and rust out, causing exhaust leaks and hindering performance.

Kooks Construction
Kooks long tube headers for your Mustang feature 304 stainless steel tubing, the primaries start out at 1-3/4" and stepping up to 1-7/8", and collectors with O2 bungs welded in. Constructed of 16GA 304 stainless steel tubing with standard 300 cell high flow cats will ensure increased airflow and performance over the factory mid-pipe. Ensure the exhaust system on your GT350/R Mustang is performing properly with these made in the USA long tube headers and high flow catted x-pipe from Kooks!
