I'd also buy some header paint and sand down the spots where the coating is peeling off and spray them.
I actually like your idea. I noticed the y-pipe I received is much better than the stock one, but I didn't know it was better than Speed Engineering.
OK, so I'm trying to prep my car for installation in the next few weeks - month. Here's my check list, can you guys proof read for me if I missed something?
-Delete EGR and AIR and block off EGR on Air Intake Manifold. (Can't go LS6 or FAST for a while.)
-Buy Gaskets for headers. (Can I use ANY header gasket? Or do I need one specifically for the brand she gave me?)
-Buy Two O2 extensions.
-Buy Spark plugs, wires, wire sleeves (because, you know.)
-Blast the hell out of all my bolts with liquid wrench.
Then I'm good to go? (Have the exhaust shop do the rest?)
