Re: performance mods on hemi
I am satisfied with the Air Aid dry filter Jr kit that keeps the stock filter housing and changes the intake tube for a smoother flowing unit. I also did the TB ground mod, cleaned and hand ported the TB with good noticeable results on low and mid range.
As for a tuner, go with Diablosport, that's the best option, the InTune works great.
The cat back has divided opinions about it`s possible performance improvements since the stock cat back diameter is 3 inches, many recommend just swapping the main muffler for the largest Magnaflow you can fit and use the stock piping and resonator. That gives it a louder but drone less tone.
