dougs header d450

I have had both in mine, the Dougs were easier to install than the tti's. I did not have to remove torsion bars or steering column to install the dougs, however, the dougs run very close to the brake prop valve. Both headers rub the steering linkage, I jacked the Dougs up before tightening the header bolts and it helped minimize the rubbing. The tti's are better for performance.
