So I have a stock TPI 350 and want to get a couple parts for it before they stop making the ****. I want to get SLP intake runners Link, and an SLP Cold air kit Link with an aifoil Link. about how much of a HP gain would I see with this stuff? Then I want to get some kind of headers, a high flow cat, and this Borla cat back. What headers would you guys reccomend? how much would it be to get them installed? Thanks. So with all of this stuff would I see a pretty good HP gain? I want it to be faster than my dads 05 Mustang GT...

 

Not much. Save your money for a set of ASM LTR's. As for headers see the exhaust section. For a price? More then you would want to pay.

 

Go for dyno don headers or the hooker 2055 but to beat a mustang you would need to port your tpi and chip and a good tune to beat him if you want some SLP headers i seeing some in Los Angeles craiglist for $300
