I have a 2006 F-150 XLT Super Cab...is the factory exhaust just a bolt on? I do not know much about all this, but someone told me if I was looking to replace the factory exhuast - from the cat back - then it is just bolted on and it would be a piece of cake to take the factory off and put the new one in. Anyone know if this is indeed the case?

 

Bolt-on? Yes.

Piece of Cake? No.

I removed all the factory exhaust for my '08 Screw from the Y-pipe back without cutting but it wasn't easy. Mine is 2 yrs younger than yours and in a milder winter environment and I still had to use a fair amount of WD-40. My advice is to attach a ratchet strap from the hitch to the hanger on the muffler and ratchet it down until it breaks loose.

 

glad someone asked this question. im wantin MRBP duals and was worried about takin stock pipe off. think anything other than wd40 would work better? i was thinkn brake-clean or liquid wrench

 

I just used WD-40 pulled with all my might. Try the ratchet strap. It should work.

However, I have family that work in a machine shop doing parts for the coal industry and they swear by this:

Said that it has unstuck even the worst rusted parts they have dealt with.
