    Flowtech introduces their new 4 to 1 LS turbo headers for the popular GM LS-series engines. These headers offer a perfect combination of quality and value for your performance application. Featured in stainless steel mandrel bent tubing with various finishes for lasting longevity and outstanding durability for both street or strip vehicles.

Flowtech once again delivers a leading edge over the competition with these LS turbo headers!

  • Up and Forward, mounting configurations

  • 11540 is rated 3.0 out of 5 by 1.
    Rated 3 out of 5 by from Headers Headers still aren't installed but they seem well built for the price point. My beef is with the v-band flanges. These are not standard flanges. They are hubcentric which is nice if you plan to use the provided flang, but I was going straight into a 3" to 2.5" reducer that was machined with standard v-band flanges. This part doesn't work so i'll be using the provided flange. Not a deal breaker but should be known. Also, plan on picking up a couple of 3" clamps because the clamps in the box need to find the trash bin.
