Right now I have a Maganflow SI/DO (straight out the back) and have considered either dumping the exhaust right before the axle or having new pipes bent to have it exit the side (Lightning style).

What do you think an exhaust shop would charge for each? What is reasonable so I don't get screwed.

I got one of the first Magnaflow kits for the new F150s and the shop that put it on said the fitment was pretty poor (for the pipes running around the spare tire). Now I have developed a squeek from the exhaust rubbing in two spots, so this is why I am considering the change.

 

Do you plan on trying to reuse your existing pipe? If it is good shape probably just the labor to bend and reinstall pipe roughly prob $100 bucks. Prob is if you need to redo all the pipes after muffler. If you plan on alum pipes prob wont cost that much I dont know about cost of stainless pipes might wanna look at the cost of the kit if the pipe and labor is more than $250. Im looking at the same kit wondering if i should keep my side swept or do the same thing. COst of the kit for mine is $515.00 or $165 for the muffler
