Please don't mess up your Excursion. Your truck looks very nice. Stacks should not be installed in a Excursion, its rediculous?..stacks thru the interior? Thats as bad as people cutting their pickup caps to run the stacks out the cap's roof..look for some pictures of that ..it looks horrible. The resonation, heat, and lack of space would totally make your Excursion un usable. You could not put them behind the rear seat also as mentioned as the fuel tank and rear axle would get in the way ..if you installed them behind the front seats ..you would lose the rear seat seating area... which would make a Excursion useless. If you want stacks get a pickup.. both of my pickups have stacks .. it allows the truck to still be used as a truck. You can still haul things, and still be able to sell the truck or easily remove the stacks etc..if you cut the floor and roof of your Excursion to install stacks you would ruin the resale value of your Excursion, you'd lose seating capacity, and introduce a host of possible problems, vibrations, water leaks, heat and interior noise. The only way it may work would be to run them up the outside of the truck. But a 4" pipe has to be supported and allow the doors to open etc.. The Excursion exteroir does not have gaps in the door line etc..ie both doors meet with no separating post and the rear doors close in part of the rear wheel well, so the only location could be in front of the rear bumper and up the quarter panel. I can't think of a support bracket that would hold the weight of a small stack 4" etc and not marr the body ..
Some one please photo shop a few pictures with interior shots with large pipes running thru the floor, pictures of external stacks with ssome support braket, and some roof stack ideas.. and help cafercr35.
