making improvements

[OnTheProwl24]

First off I just became a proud owner of a 03 marauder with only 26000 miles for $14.5 and I love the car and I'm already looking to make improvements and I need yall help because I'm not really mechanically educated ok everything I'm planning to install is from reinhart automotive
1. Either a k&n or jlt Cai which one is better?
2. Pulleys
3. Kooks long tubes exhaust
4.4.10's
5. Torque converter
6. Sct tune
All of this is random order but I would like someone to tell me how much HP and torque u think all of this will generate and if I need anything else to make all of these improvements perform correctly thank-you

And one more thing I know this is a marauder club and some of you will be bias but I would like a honest answer I was stuck in between this marauder and a 06 charger srt8 with 56000 miles on it for $23k but I got the marauder if u had the same choices what would u have done honestly don't be bias thank-you ahead of time for your responses

First, your mod list should get you close to 300 rwhp, just substitute the SCT tune for a custom dyno tune (Note: Today's canned tunes may be equal to dyno tunes, just talking from the past).
Second, you made the same choice that I would have.
Third, no question or doubt about it, go with the JLT CAI. Far and away the best.

Wow, I wish I could've got that lucky for the price. :(

Skip those mods and start with a supercharger. That will by far get you the most bang for your buck. Then do the Kooks when you can. Won't need a TC and gears after the blower unless you're just trying to make it haul as much ars as possible while sacrificing some level of comfort...

jlt. if your going s/c any time in the future do kooks after the s/c then dyno tune. but if thats years from now and you cant wait get a xcal 3 first its a must for 410s and pullies and make sure its steeda pullies

I see you picked up the Marauder, good choice if you got the Blue one. It's the rarest of all!

Tune, intake, pulleys and 4.10 gears are good mods to start out with.
