Add catted connections to your Mustang header upgrade
For a naturally aspirated 5.0 Mustang with Kooks long tube headers, 11513200 supplies the 3-inch Performance-catted front pipes. The 300-cell cats are part of this exact product, with 16-gauge 304 stainless tubing and ball-and-socket header connections.
SKU: 11513200
Match the cats to your engine
Choose these pipes for the listed naturally aspirated GT / Dark Horse 5.0 applications. The Performance cats are not recommended for forced induction. Your engine specification matters as much as the model year when choosing the catalyst version.
Choose one rear connection arrangement
Clamps are purchased separately. To retain the OEM-size rear exhaust, add the separate 11513000 adapters. A matching Kooks crossover that includes its own adapters and clamps is an alternative arrangement; choose the parts for the rear system you are fitting.
Matching products
For a 2015-2026 GT 5.0 using OEM-size rear exhaust, the GT 5.0 OEM adapters are supplied as a pair and require fitting clamps separately. For the same GT 5.0 header-and-connection installation, the ULTRA X-pipe offers a crossover with its own mid-pipe adapters and all clamps, as an alternative rear connection.
