More Horsepower and Torque. Replace those heavy and restrictive cast iron factory exhaust manifolds with a set of Flowmaster's Scavenger Series Elite long tube headers that will improve exhaust flow to increase your Pony's horsepower and torque.

Quality Construction. Flowmaster's Scavenger Series Elite long tube headers are made to last using free flowing mandrel-bent 1-5/8" 409 stainless steel tubing, 3/8" thick laser-cut one piece flanges and factory style collector connections that ensure a direct leak free fit.

What is the preferred mid-pipe AM has that will fit these longtubes? I noticed there aren't any Flowmaster mid-pipes for the 2010 on the site.

  • When doing long tube headers you will want to match the same brand header as mid-pipe for proper fitment. We strongly recommend not mix matching brands as they may not bolt up.

I already have Flowmaster cat-back exhaust on my mustang, do I still need to get mid pipes in order to put these long tube headers on my car?

  • Hello, Yes you would be required to have a mid pipe it will work with stock mid pipe as well

Is this type of Longtubes able to be compatible with other types of Off-Road H-Pipes or is it only compatible with it’s own brand to stay together? Just wondering since my car is an ‘06 GT..

  • These Flowmaster 1-5/8 in. Ceramic Long Tube Headers can work with other headers, however, we always recommend staying with the same brand with headers and mid-pipe due to manufactures differences in tolerances.

Could I use these with my V6 mustang? With the BBK True dual Conversion Kit?

  • The Flowmaster 1-5/8 in. Ceramic Long Tube Headers will not work with the V6 due to differences between the engines installed in each.

    Beauty And The Beast

    I bought and installed along with Flowmaster off road shorty X pipe. Wow the car is angry fire breathing beast. I love the sound and I still have stock mufflers in place. I wanted to put Flowmaster Hush power mufflers on to cut down a bit on the rasp, but it seems that they have been discontinued. The headers them self are beautiful! I will have to shop around to see what mufflers I match up to them.
