Manufactured from 1-5/8" mandrel bent 304 stainless steel tubing Kooks Long Tube Headers are TIG welded for strength, and feature a leak-free ball flange design to fit perfectly into the included 2.5" diameter 304 stainless steel Shorty X-pipe for excellent exhaust flow and performance.

      If I get this header and off-road combination, would it go hand in hand if I also buy the magnaflow exhaust system bolt on.???

      • This combination will work with Magnaflow cat-back systems as the flanges that connect them are the in the same position and the piping size match up at 2.5".

      Automatic fitment? Do these have fitment issues with automatic 98 gt's like the bbk's do? I know the Slp longtubes will fit but I'm looking for a matching o/r x or h pipe which Slp does not offer.

      • This Kooks Header and Off-Road X-Pipe Combo - 1-5/8 in. (96-98 GT) should work just fine with an automatic transmission.

          Kooks headers OffRoad X combo

          Kooks headers and OffRoad X combo is easily the nastiest exhaust setup around. It has a growling rasp like no other it is literally the best sounding exhaust for these mustangs. I highly recommend this set up, you won't be disappointed!
