I have a 2007 R/T with 90,000 miles. Trying to add HP. Thinking a K&N cold air intake and Super 44 Flow Master exhaust system. Any other some what cheap ideas?

Well, Let me start by telling you that power doesn't come cheap! Getting more air in and getting that air out efficiently is a good start but it comes at a price. You see these cars being computer controlled need to have the tuning altered to realize any real permanent gains. Fortunately, tuning is available via Diablosport handheld programers. https://www.diablosport.com/


If all you want to do is what you mentioned then you may see some benefit but not as much. Better sound for sure though.


There are 3 programmers available for the Hemi......... The "Predator", "Intune" and the more feature rich "Trinity". The "Predator" is a discontinued programmer that can sometimes still be found used for less money.


With the Diablosport tunes, a cold air intake and exhaust you can expect to gain 20+ rwhp and 20+ rwtq.

Fireman has spoken, so shall it be. :)
Not sure what your HP goal is but keep in mind you already have 90,000 on that motor. I would not want to start throwing too much money at it trying to make big power gains.

I agree hollywood448. That being said, I am not going to be getting rid of the magnum anytime soon. So what are we talking about to get the motor rebuilt with a little bit of umph to it? Sorry, I am new at this. Thanks for all the input.

Me personally don't mind putting in time and $$ into my mag, I don't think I will ever get rid of it. When things go that is the time to upgrade!
I would start with, CAI, TUNER, EXHAUST, THERE are some small things you can do look up the ultimate how to, if I remeber there is a list of free or low cast mods. You can remove the air silencer, and flip the radiator baffle to direct more air in.

As long as you aren't burning oil and the motor is solid, 90K miles isn't too much to work with. I have 110K on my '05 5.7 and I'm pushing almost 500hp without any problems.

As long as one stays n/a or replaces some internals before adding nitrous or supercharger/turbo I would agree. IMO, one would be running a risk of damaging the motor by throwing boost or nitrus at it without checking/upgrading some internals first. Doing the basic upgrades will wake it up some. Add the transformer and enjoy.

My God has it been a year?I guess that's what a 3rd kid will do to you. Thanks for the advice. I ended up putting the K&N cold air intake. Held off on the Flowmaster 44's...until now. I do have a question though. I bought the 44's only cause I was thinking, the American Thunder exhaust kit can't be that hard to match at a local exhaust shop, can it? Am I wrong to think this or is that kit that much better than what a shop can do? Either way the 2 Super 44's are going in. Thanks for the advice.

procompmagnum....wish, just a little pricey. I'm thinking about going with adding the Super 44s and getting some Blastin' Bobs Fat Pipes to go with them. Looking for some good rumble and possibly a bit more horsepower.
