Exhaust question
 

Hey guys I had a quick question, Im thinking of buying JBA LTs ans H-pipe with cats. I already have the JBA axle-back, does anything else need to be purchase as far as piping goes? Will I need oxygen sensor extensions and high temperature head gaskets?

I'm also looking to buy the Predator tune and the C&L racer CAI. Is that a good choice? Will a canned tune be sufficent for a new exhaust and intake. I know a custom tune would be better for optimal proformace but will the canned to be ok?
