Friday
I put on my 4" MBRP exhaust with kitty intact.
HMMMM
wasnt ear as nice of fit and finish as the magnaflow on my 7.3
However I did like the pipe going over the axle from the muffler is all one piece, made it easy to align
the turbo downpipe was a major PITA to get aligned so it didnt hit the body pinch welds and the bolt heads on the cross members.
also the factory down pipe what a turkey it was coming out.
good thing i had my ryobi cutzall recip saw. vrooom like butter
rest of system went together real easy.
as for temps
right off it ran 150 cooler at 65 mph pulled 550-650 at 83F outside temps
cooled down to below 400 at idle relativley fast , under 2 minutes
seems to have helped the turbo lag, which surprises me. it spools up noticably faster. really
the in dash mpg gauge gained 2 mpg at 72 mph over a 20 mile trip
the 2000 rpm droan is gone gone gone
sound is not loud, has a nice deep rumble at first start then the turbine kicks in to a nice low whine.
accelerating.... with rear window open sounds nice and with a smooth rumble, not offensive
with windows closed I cant even hear it.
and the 5" tip i know added .5 mpg just because it looks so good
some items that needed a slight modification
there is a wire harness at teh end of the passenger side valve cover that is wrapped with black convoluted tubing on its entire length except for teh last 2 inches. this part is wide open to the extreme heat from the turbo downpipe
so I wrapped the rear and one jus tforward of it in a black membrane reflective tape and manufactured a heat sheild 3" x 6" to deflect downpipe heat away from teh wires.
and I shined a flashlight thru the kitty. I could see light although it was very dim
