exhaust is usually the first place people look at. a good set of headers and higher flowing exhaust system will usually net you some gains. which model tj do you have?

Cheap & Power does not exist in cars. None truer than the magna.
The magna's are pretty well strunge out and aftermarket modification parts, especially for power, are few and far between.
There's nothing cheap that provides a considerate improvement for the magna.
Only thing would be a free-flowing less restrictive exhaust that will get you around 6kws at the flywheel. Nothing to sing home about. Continue with high-flow cat and extractors and you'll have a more usable power curve and a nice note, but no real step up in power.
If you're willing to give up the slushbox, then a manual conversion will give you power at the wheels and a much raw and fun experience. Never looked back on my decision to convert.
Don't bother with fancy overpriced and overhyped aftermarket pods, intake manifolds etc. Factory setup is best.
Otherwise for the odd 2.5-3k you can have a 380 engine fitted which will give you nearly 200kws at the fly (150ish at wheels).

I may consider putting a 380 engine and manual in how much you think that would cost and to have fitted ?

Labour charges could be an easy 1k if you're going to pay someone from start to finish.
You then need to consider the cost of the gearbox and engine plus clutch & flywheel and of course; belts, pulleys, pumps, gaskets which would be a wise thing to replace while the engine is out of the car.
In all, I'd be budgeting at least 4-5k for the lot. And that's fairly conservative at that. Gearboxes can be cheap as $300 if you know where to look. But clutch's are min $600 and flywheels $700. 380 engine's are fairly pricey due to their rarity and increased demand for magna's. Not sure about WA, but here you'd lucky to get one under 1.5k plus all the serviceable parts (belts, pulleys, gaskets, pumps etc) which could be anouther easy $800.
Costs can esculate qute badly. Personally, I think it's the wrong car and chassis to do such serious work too.
Why not just get a manual first and see how you go and whether it's enough power difference for you. The 4sp slushbox restricts a good 15kw from the wheels. Very noticeable difference.

I would recommend having a search through the forums as there is a lot of good information on this topic already.

Yep, plenty of info if you look around.
Cheap, easy, kilowatt effective mods don't exist.
From cheapest and least effective to most expensive:
cold air intake
different color plug leads
high flow exhaust
manual conversion
380 conversion
turbo or supercharger
But if you are limited for cash, time, mech skills, just leave the car as is.

Theres also aftermarket ecu chips, or options of putting a ralliart tune in yours, ralliart cams (hard to find)
Theres also extractors but I paid $895 for my 2nd gen, I think a 3rd gen magna would n3 cheaper

Not only is a aftermarket chip illegal, its completely useless for a stock as a rock magna. The point of chips is to make use of any new engine modifications that would alter the engine and/or power output enough that a the ecu can no longer properly run the car and you'd not be using thenfull potential of the new setup. Unless the op is going to change something signifxsnt on the compression, intake, timing etc of. Thief engine, or the engine itsf, there is absolutely no need.
If th had a 5sp auto then you could potentially argue for the ralliart runs so the shift points would be more aggressive . But rjsy have a a sokara which came with a 4sp auto.

The most "bang for buck" mod for power would be a manual conversion and a free flowing exhaust. Significant and noticable difference. And can be done for under 1.5k. In manual you'll soon find the the cat has too much power for a FWD large family car. Almost no tyres will prevent wheelspin on a wet day, and through corners you definitely feel the limitations as the car under steers, tram lines and torque steers through corners. Its very unsettled.
Spend the money you would on a 3)0 engine getting stiff struts and bracing. Coupled with a manual and it'll bs a completely new raw car.

Straight through muffler
High-flow cat converter
Grab a spare ECU, send it down to SKR in SA and get a postal tune.
HM headers for down low power off the mark, or pacemakers for top end roar.
15kw gain roughly from all of that. That's a 10% increase in power which should bring your car up to around 165kw at the flywheel.
Change your spark plugs and leads, replace your dizzy cap/rotor, use a high quality engine oil, flush your transmission, change your alternator and power steering belts. Nice, clean fresh engine for all your newfound power to go through.
