I am trying to figure out what is the best way to go with my 2012 challenger I understand that the more air you can put into an engine and the same with the exhaust the more horsepower you can produce. I do not want to go with the supercharger or change the cam.

My only Mod so far has been a Mopar CAI.

I am trying to figure out who makes and would fit into my configuration for a throttle Body Don't know if I should even go up to a 80mm depends on the warranty

As for headers don't really know long or short, make or model. I am thinking about getting the (3") Borla Atak exhaust system with Electric cut outs.(suggestion here would be helpful also)

Would Like some feedback if you can.

Thanks Kevin :scratchhead:

I have the kooks long tubes and borla atak. after hearing the car at WOT on the dyno I decided it was plenty loud and didn't install cut outs.

Is this a 5.7 or SRT? If it is a SRT it already has shorty headers on it so I would only go long tubes for the most bang. The TB is 80mm stock so your choice are 85 87 90mm. 85 and 87mm are the most popular,

Long tubes will net you much stronger gains than shorties. If you get the Kooks long tubes and their midpipe it will bolt-up without modification to any of the aftermarket cat backs.
