With or with out a hood scoop?

It's just really whatever you want to do. I always really liked the look of the snorkel hood myself. One thing I will mention about your Duster; get some different rear wheels with more inside offset and get as much of the rubber inside the quarter panel as possible. Just a neater look. Just my opinion.
The car was sitting lower but the tires and headers were scraping on dips on freeway and street, I had to raise the car up in the front by the torsion bars, and get rear caltrac springs with a taller ride Hight. The wheels off set are wrong, the wheels came with the car. Those weld wheels are pretty expensive, I will get ride hight down after I buy the wheels with right off set.
