Scan Gauge Install & my dual exhaust

OK this pic is my ScanGauge install. As most of you know, there aren't a lot of places to "cleanly" install the ScanGauge so I created a spot.

If you're interested, the first thing you need to do is make a template; use some fairly heavy duty cardboard because it will give you a realistic version of the real thing. The cubby where I installed mine isn't "square" so take your time with your template. I bought a sheet of 1/16" ABS plastic from Tap Plastics. Tin snips work great when making the initial cuts but you'll need a Dremel for final sizing.

Cutting out the slot was the biggest pain: I used masking tape over the area & then laid out the dimensions where I wanted my "slot". I drilled a 1/2" hole where I wanted the cut-out to be and then started slowing cutting pieces out (I used razors & wire cutters mostly) and then "dremeled" it for the final dimensions. I recommend at least 1/2" space above and below the slot & when you bend the plastic you'll know why.

NOTE: CUT OUT SLOT BEFORE YOU BEND THE PLASTIC!!!

Bending the plastic wasn't all that painful. Neither a hair dryer or Bic lighter will work. I used a portable "blow torch" with the fire set on lightest possible setting. I then clamped the plastic to a metal straight edge to get a perfect bend and "ran" the torch along the straight edge until it started bending. I bent mine a little past 90 degrees so while the plastic is malleable you'll have to help it past the 90 degree mark.

NOTE on ordering a sheet of ABS plastic: I was looking to buy a 16" X 16" sheet in case I screwed something up. When I put in the dimensions I wanted, it turned out that a 16" X 16" sheet cost the exact same as a sheet of 24" X 24" (the postage was the same too), so I ordered a 24" X 24" sheet so if anyone is in the Tampa area I have plenty of extra. The sheet was $10 and postage was $12 but they package like they're mailing something very fragile.

There really isn't a way to "permanently" install the piece of plastic you just made so I put foam under it and then "tucked" it down where the back of your cup holder is. The cup holder is held in place by 2 plastic clips so it comes out really easy.

I'm pretty sure I didn't explain some of this exactly right (and am also sure I sounded like an idiot in spots) so IM me or post a question if you have a problem.



Here's my duals (I don't have a good of the Thorley headers).
