5.7L upgrade

[05MAG_R/T]

I have a 2005 5.7 R/T and im thinking about starting to upgrade my engine but idk what to start with, im really into speed, sound, and performance. everything is stock in the car. If anyone could tell me parts that would be great to start off with and where i should go from there would be great. Thank you.

Cold air intake is a really good way to start... And throttle body spacer is nice too...

Think the norm is cai, tuner (I use an intune), exhaust. I'll let other people tell you about the tb spacer lol

I'd skip the TB spacer as well. Chutlu is right on the money: CAI, a good & versatile tuner, and the exhaust setup of your choice.

I'd agree with the two above, Intake, Exhaust, and Tuner are good things to start off with

Based on the advice of everyone here I went with the CAI and tuner so far and after two weeks I'm still skipping and grinning for an hour after I park.
From what I understand the exhaust is preliminary to future upgrades and with the CAI and Tuner will only make the car sound faster.

Best $600 I ever spent!

Tuner, CAI and a catback exhaust. If you really want to help the Hemi breathe, you'll also need to install headers as the bottleneck is at the 5.7 exhaust manifolds.
After that, it depends on how much power you want and how you want to achieve it. Do you want to stay naturally aspirated or do you want to go forced induction?
For some, adding the CAI, tuner and exhaust is good enough. 20 additional rwhp and rwtq can be had with a tuner and CAI. Installing headers could add another 10 or so.

Does it matter if we go with a K&N CAI or is anoter brand out there better? Im looking to start with some engine mods.. I have a nice stock 5.7.. Nothing done to it at all except the usual maintenance.. Gotta let my Hemi live a little.. lol

You can build your own "real" CAI for less then an aftermarket one. If you take the air silencer off and get the right plumbing, you'll be able to route the cone filter to in between the fender and wheel well. Start with looking at the pics on this site. Fireman just had one installed and looks awesome. You can buy one like his, or make your own.

CAI and exhaust is a must. Then programmer & headers. Results will speak for themselves.

And a 180 thermostat is cheap and easy, and the tuner will adjust your fan temp down. It will run about 185 on the highway anyway. ($30)
A good CAI will also sound good and add another 5 HP or so on a few of the best. (Build it for $100)
A unmarried Predator will add a few more HP and up to 20 with a custom tune. Shifting will be improved. (About $250 plus $200 for a Email tune)

Probably the best sound to be found is the Corsa Extreme cat back system. While you're at it, find a SRT exhaust manifold and mid pipe take off, and match the new Corsa to that. (About $2200 total, but worth it)
Realistically, you'll only gain about 30ish HP at this point, but you now have a structure you can expand on.

A cam is the biggest difference you'll find in performance, but needs supported by the exhaust and CAI change, and 6.1 exhaust valve springs. ($550)
Stock heads flow pretty well until you get into really big cams and other intake manifold modifications. Cams are easier to change with the heads off, and milling the heads 0.030 will add about 15 HP and marry you to premium gas. (Spring change and milling charge).

good advice is hard to come by but damm lol that pretty much summed up everything i been thinking about
