I am looking into getting a Hemi Ram in the near future and if I were to get one I woulf probably get a Flowmaster Catback and a K&N Cold Air Intake. I was wondering how much HP do you guys think I would gain?

 

I have Magnaflow dual cat back and the K&N CAI and from what I have read or heard on DF is you will pick up around an extra 5-10 HP. Can't say as I noticed a huge jump in performance, but it sounds terrific and I also think it helps a little on the MPG.

 

I always assume the dealer is full of crap so I cut the gains they claim by half.

 

I vote for closer to zero.

 

I have a cold air intake, flowmaster 40 dual exhaust. It just makes it sound cool, maybe a little better mpg. But performance, idk probibly nothing.

 

Probably would gain around 15-20HP from a cold air intake and exhaust. But a 20HP gain is something you would really feel.

 

Nicky B, you have dyno sheets to prove this? If not please stop spreading bad info.

 

Well, Flowmaster DOES post dyno sheets for each kit...question is do you believe them, and do you know how they ran the tests.

Same thing with K&N.

 

If you really want to know put them on and get a dyno done. Or ask the manufacture's tech exactly what was put on the vehicle to get the dyno results and then do the same to your vehicle.
