Choose an H-crossover for your Mustang header exhaust
Keep your OEM rear exhaust and add a 3-inch H-crossover after the Kooks headers and connection pipes. 11513600 uses mandrel-bent 304 stainless tubing and supplies the mid-pipe adapters and clamps together.
SKU: 11513600
A complete crossover connection
The included adapters and all clamps connect this H-pipe to the OEM rear exhaust on the listed 2015-2026 GT / Dark Horse 5.0 installation. Choose it as one rear-connection arrangement for the matching Kooks front exhaust.
Compare the crossover styles
The H-crossover connects the two banks through a linking pipe. The ULTRA X-pipe is the matching alternative if you prefer an X-crossover. The retained mufflers and front exhaust still play a major part in the sound you hear.
