Releases the Full Benefits of Upgrades to Induction. If you’re investing time and energy in upgrades to your Mustang GT’s induction, especially if you’re going for forced induction from supercharging or turbocharging, you also need to open up the exhaust flow so your Mustang breathes more freely, releasing the benefits of those mods. These Borla Long Tube Headers with X-Pipe are optimized to replace the stock restrictive exhaust system from the head, deleting the cats for a huge improvement in exhaust-gas flow.

Full-Throated Race-Exhaust Roar. The big, 1.75” Long Tube Headers really let your Mustang sing. With their 2.5” collector, they’re less restrictive and, with the cats gone, there is little to impede the full-bodied race sound. The crossover X-Pipe just adds to the music.

Deletes the Cats. These headers are designed to remove the catalytic converters from your Mustang. They’re intended for off-highway use and will not support any need for emissions-legal operation.

Skilled Construction. Borla builds its Long Tube Headers and X-Pipe from 16-gauge, aviation-grade T304 stainless steel. The tubing is mandrel bent to achieve smooth, restriction-free gas flow from the 1.75” primary pipes to the 2.5” collector, which uses a stock flange for maximum compatibility.

Calibration Needed. Optimized to support extensive modifications and tuning to improve engine breathing, the Borla Long Tube Headers produce real results with calibration. Expert tuning of your Mustang’s ECU will allow the full benefits to be realized.

Application. The Borla 1-3/4 in. Long Tube Headers with X-Pipe are designed to fit the 2005-2010 GT Mustangs.
