found a company on ebay called custommustang.com that has a pi intake kit for 285.00 + 25.00 shipping. has the gaskets, coolant tube, etc. even the aluminum crossover has the second hole drilled out for the other sensor. thinkin about getting it. what can i expect from this pi intake? obviously some power, but does the exhaust sound different? heard a few say it does. any thoughts?
