Not necessary. You can save some money by buying a 2" wide, 15' roll of header wrap. Did mine that way and it was pretty easy and effective.
No need for a u-bend delete as a bolt-in downpipe will have that already deleted. I agree with the suggestion to skip the rear ported manifold. Save your money on that and put it into the rocker fund. The rear PEM will give you like 3 hp at best probably. If you take apart your exhaust in one sitting, you could just use a dremel to touch up your stock rear manifold if it even needs it.2.Downpipe
