My friends dad just bought an 05 Ram with the 5.7 Hemi and I was wondering what perfomace mods were avalible. He wants to get dual exhaust for sure and maybe a power programmer. What would be a good place to start as far as the mods go?

The exhaust and air intake are always good places to start as you know.
I know some of the site sponsors have offered specials on headers for the Hemi, as well as offering programmers from Hypertech and/or superchips. Of course you can go real crazy with an STS turbo system. I think i remember something being offered on Dodge Forum as well from our vendors. Might want to do some searches in that section for what they have.
I heard that the programmers can't improve too much on the 04 and up 5.7's. I'd focus more on headers, exhaust and intake.

buy the sts turbo! Great top end performer. A lot of thought went into this system!............... WORTH THE MONEY!
I have an 04' QC 4x4 AWD hemi with stock 3.92 gears. In stock form, I ran it down the 1/4 mile at 16.64 seconds.
I just finished installing The sts turbo with boost controller, and their air to water intercooler. I haven't finished tuning the system yet, but let me tell you, from zero to 60, it feels like a 15 second truck, and from 60 and on it feels like a high 12 second truck.
I suspect 1/4 mile times to be mid 13's, and top speed easily 150mph+ (past the speed limiter) when all said and done. Pretty damn good for a 3 ton tank!
I have an APS 2500 stall converter on the way, and thoughts of a dual set of 4.56 gears in the future as well.
Yeah...Getting a turbo is a nice mod if your a MILLIONARIE! J/K Its a good one if you have 6G's lying around. Unless you wanta race your truck. But for an everyday driver I would go for the easy stuff.
YO HE WAS SHOOTING FIRE OUT HIS EXAUST???!!! WERD YO, I BET HE SPRAYED A 300 SHOT OF NAWSSSSSSS AND YOU STILL SMOKED HIM WITH A BLOWN FUEL RAIL FO SHIZZLE das wassup
Speed (power) costs money; how fast do you want to go?
I've done turbos and various superchargers (Vortech, Paxton, & Kenne Bell); on the street I think the Kenne Bell is definitely the way to go. Just my $.02 having comparative experience.
However, fueling and tuning options available for any given system will make or break any blown application. If the tune is not well researched from the blower supplier, one can spend about as much on dyno time as the setup cost and still not always get things right. Unless going with a well established tuner's product, I'd want to drive (or at least ride in) any blown application in my engined vehicle before buying, especially if in kit form.
All the best.

Yes, I installed the turbo myself! took a couple of really hot days to do it on the driveway, but i was so f'n happy when i first started it up!. Special thanks to kenihemi for the system.
I haven't been to the track yet, and my aps 2500 converter just came in.
I'm still learning how to drive the truck in high boost. inbetween shifts, the throttle plate closes momentarily locking pressure in the intake which floods the engine if you're not careful. Thankfully, kenihemi and his band of merry men have devised a solution to this problem with a diode mod for the map sensor, which i'll be receiving shortly.
I was also thinking of installing a relief valve on the intake manifold to help reduce pressure buildup under these conditions.
I've got the STS system with an APS converter. There are random folks out there selling the base kit for about $4200 or so. I also put on an smt6 piggyback system to control the fuel and to handle that map sensor stuff. Ktmrider came up with that adjustable map sensor mod that you can dial in to whatever altitude you're at and it works good. I believe Kenihemi is running that one too. But I just let the smt6 handle my map stuff. I have a 4x4 QC with 92lb motto 20x10 wheels. Here is video of my big ole heavy truck doing 0 to 70mph. Oh, and this is only at 6psi boost. Excuse the country music.
