Will this work with other longtube headers such as pacesetter or Mac? And if I convert to dual exhaust which setup will I need?

  • The Flowmaster Direct Fit Catted Y-Pipe will only work with shorty headers, but it's anticipated use is for a completely stock application. This will not work with a dual exhaust setup as well, since the dual exhaust conversion will include a X-Pipe.

    Flowmaster High Flows

    The tone these cats give your stang is absolutely incredible. Startups and forceful and sometimes your treated with a glorifying crackle, at low speeds, nearly idle, you get that classic muscle car metallic rumble, from there, hitting 3k, 3.5k, the tone gets so rich in depth and volume. I haven't rolled my windows up since putting these on. Next, the power is definitely noticeable. She pulls much harder now, these cats a great for someone looking to had tone and not necessarily volume, it still is plenty loud for a daily but with our v6's this a perfect way to add a beautiful tone and power without "trying" to be a v8. Id recommend a shop if you live in the Northeast.

    Perfect fit for the 2005-2009 V6 Mustang!

    This is a pretty straight forward install, as there’s no welding required and you bolt it on to your stock headers! If your catalytic converters are original and old, upgrade them BEFORE they clog and overheat your headers/engine! Plus, these are high flow for better performance. If you have a dual exhaust, just cut these pipes befor the Y.
