CrystalSS

If Hood clearance is not an issue which is a better choice? I have an Impalass with ported heads, a 230/236 comp cam, 1 5/8 x 2 1/2 collector as&m shorties, 2 1/4 borla full exhaust, runs 13.2 at 102.22 in 1/4 mile. I was ready to order my 29135 super victor but the HSR has been in the back of my mind. After comparing several dyno tests it looks like the HSR is the way to go....
Or are my headers holding me back? considering 1 3/4 long tubes!
