The J tubes swivel. You can point them anywhere you want too ...... well not exactly true. The O2 wires aren't long enough to point them backwards without a wiring extension. I have them pointed forward and slightly down so they have 1/2" clearance from surrounding appendages. My car's low and I see signs of scuffing under the car and I'd prefer if they tucked up underneath a little more. I have a few responsibilities to take care of before a test run. I plan to get on the dyno this week, for better or worse, to see what the numbers are. YEEHAW!!
