I'm currently running an Injen - which looks/sounds okay - but just know that NO SRI is going to add HP unless you have a piggyback module with a new air/fuel map (like the CP-e).
I'm going to be getting in my CP-e MAFci the next month and will be doing a back-to-back dyno test and will post the results.
Others have dyno'd theirs compared to OEM and have posted the result quite favorably, but I want to compare Apple to Apples and see how much better the CP-e is over the Injen.
Like I said, the Injen is a known brand and makes a lot of noise, but no performance other than what you "think" it might be doing under the hood!
Oh yeah - I'm talking about the V6 here to - not the I4 BTW.
