2011 RT challenger performance questions.

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

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.

2011 RT challenger performance questions.

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.
