I been reading the posts for awhile, and looking over the net and such and have settled on the MagnaFlow SI/DO catback system, (#15749 I think...?) for my 1999 F150 XLT 4.6. Anyways, I would like to tackle it myself since it is supposed to be a simple bolt on replacement package. I have done a few things to my vehicles on my own but I am by no means a mechanic. So, from you out there that have done this install, is it as simple as it is supposed to be? Any oddities or peculiararities I should be looking for? How about special tools or materials? I'll be checking back while convincing the wife to let me spend the money so any help and or tips will be much appreciated. I love this forum and have learned quite a bit here already.
Thanks
James

 

the si/so uses the stock hangars. i dont think the si/do does. it should come with some bolt on hangars or something, otherwise you might need a shop to weld them into place.
