Do most of you guys that have headers run under the first crossmember or over it. Just mounted some headers to my 2" lowereed 350 and they come out nice but under the crossmember thanks

I have a 3/5 drop( + 1 1/2" body drop) on my longhorn. she has a couple custom crossmembers, & the tubes are tucked up tight, but go under the crossmembers. IMO, if you arent going superlow, or plan "laying the body", there is no reason to go over the crossmember......69L (

There Are 4 Kinds Of Headers That I Know Of,

Block Hugger Style (Various Versions)

Shorty Style (Dump At A 45 Degree Angle)

Mid Length Style (Like What's On "GQ" Now)

Full Length Style (Most Common, What "GQ" Had)

Going Over The Crossmember With Full Length Is
Difficult, They Have To Put In Radical Bends To
Get It Up And Over, Sometimes They Even Have To
"peice It" With Multiple Peices To Make It Work,
Going Under The Crossmember W/ Full Length Is
The Most Common, You Will Not Have Any Issues
Like Said Above Unless You Really Slam It.
