Well today is my birthday and I'm trying to figure out the next mod for my rt. I currently have slp loudmouths and a trinity tuner, and was thinking of longtubes. Some say they are worth it, others don't. How much horse power are those going to add? 25? Should I just go with hi flow cats or an offroad x? Also I was looking at the AFE stage II intake. Is the AFE worth modifying to fit my rt? Or should I just get a regular Arrington intake? I was tempted to add nitrous, but I want to hold on to the warranty a little longer. Any suggestions?

Okay, well, after researching more I've decided to pass on the headers, but the AFE stage 2 intake? Any help?

I'm in the same boat as you. What did you learn from researching "more power" steered you away from headers? Power gains? $$$?

I think the only CAI for the 2011+ that made substantial gains was the Legmaker Frankentake IV. The rest are just for looks and sound. That's good you already have a tuner, you can then use the CAI tune for further gains.

I absolutely LOVE my AFE Stage II CAI, but then again I have a 2010. 2011+ would not yield as much gains. Dodge really did a great job making the stock intake flow so well on the 2011+s.

@c26 I was doing research and most people said that the shorties would help almost as much as the longtubes, but much cheaper. Also my dad said I couldn't install longtubes on the car. So longtubes are a no go for now..

@omaha that Frankenstein intake helps more? That's surprising to me. I would have thought the afe would have been better

Any other suggestions for mods?

fastman throttle body comes to mind or any other ported throttle body really

I just did jba long tubes and catless mids two nights ago and what an improvement. Throttle response is up, over all power is up, sounds wild. I couldnt be happier with the increase in power and sound.

I'm looking at the LMI fender pull CAI when funds free up some. I'd think it would have a slight advantage over the Frankentake IV.
