Muffler Update questions
Hey all I had spoke to a rep at Flowmaster about a cat back for a v10 Excursion. They suggested 3'in/Out big block 50 or 70 series. DO you guys know if there is one that is a easy swap out without taking it to an exhaust shop?
Thanks

unless you want dual exhaust (sounds like you are just keeping the single exhaust pipe) then buy a muffler and weld/clamp it in place. retaining the factory pipe with the use of like 10 inches of filler pipe to make up for the small muffler.
the factory pipe should be 3 inches already, so just buy a muffler and save some cash.

Ditto on what rebel says.
I also spoke with FM recently about the same thing. They used to have the kit a few years ago but no longer carry it. But I guess you probably knew that.
Depending on how good you are with tools & a welder, the F-250 kit might fit with some minor mods for gas tank clearance and more length in front of the muffler. The 50 & 70 are both relatively mild. The 50 is 18" long and the 70 is 22". I believe the F-250 kit fits a 133" WB CC while the Excursion has a 137.1" WB.
I am ordering my FM 70 BB II tomorrow, 3" offset/offset part # 53073.
To save a little money I am going to use the stock tail pipe that is 3" with mandrel bends. A friend is going to weld it for me. $113 for the muffler, free shipping to lower 48. You can get a decent stainless tip as well for about $40 and your rusty tailpipe will be neatly tucked away under the quarter panel. $153 for a new exhaust and I get to get my hands dirty!
