Steps for rack and roof access
-
Someone stated in another thread here that they got a 150* drop in EGTs from wrapping the downpipe, cheap enough, I gave it a try
No change for me, I guess your mileage will vary
-
In fact, that discussion got me to research EGTs a bit more, I thought I was running fine for the last two years, turns out that my exhaust guy mounted the probe AFTER the turbo, I didn't know any better at the time. Moved the probe to the exhaust manifold, um yeah, I have a problem - need to turn that tune down a bit!
-
After the rack went on, got some wind noise/droning in the ceiling, not surprising since the headliner was out, just one layer of bare metal - very annoying when driving, needed to put it back together before I got on the road again.
-
Ceiling insulated, bituthene-type roofing as poor-mans dynamat, and a layer of blue foam insulation as an additional sound measure.
-
The blue stuff kinda sticks to things when sanded
-
Much better

Ready for the road now...
