Time to pick your brains again.
What would be the difference in getting the Walkinshaw over the radiator air intake and remap with just a cat back Wortec, compared to what I would see from getting the headers, cats and xpipe done first?
It's about 1100 for Walkinshaw bits and 1800 for the AAS treatment.
Does the extra money on the exhaust justify the return in performance?

if it’s a monaro you have ? do the diff first , put a 3.9 in , a cold air intake and a map will give you more bhp but will you actually notice it , the diff you will , vxr8 the exhaust i think is 8 ? bhp more , cold air intake and a remap on a vxr8 is quite a lot of ££ for not a load of extra grunt , theres a you tube clip i think it gave it an extra 45 ish or so increase in bhp , a 30 bhp increase is not that noticeable apparently

If you get the headers, cats and X pipe done first, you won't see much of an increase in power. The reason being the factory cat back and the standard air intake are restrictive.What would be the difference in getting the Walkinshaw over the radiator air intake and remap with just a cat back Wortec, compared to what I would see from getting the headers, cats and xpipe done first?

Basically start withe the intake first then a cat back followed by the headers. Obviously it's better if you do at least the exhaust in one go, but cost is the overriding factor for most.
Think of it as getting more air into the engine, and more burnt gases going out the exhaust with the least amount of restrictions as possible.
Leave the remap until last, but make sure you're not going to to do anything else to the engine anytime soon otherwise another remap will be required.
One thing I did learn earlier on is when you look at individual components the manufacturer claims all kinds of power and torque inceases. Well in reality they don't do much on their own, they will only show decent gains in conjunction with other performance parts fitted as an overall package.
Your prices seem a bit off to me, are you sure you are getting like for like comparisons. It's hard to believe that Walkinshaw's are cheaper than AAS.
That is how I modified my Monaro over the years and it's worked out fine for me.

As above , it’s a collection of mods that work the best but it’s often a lot of £££ , the monaro focus pack , modified air box k and n filter , that says to me not a lot of benefit doing an otr on a monaro? , bigger intake pipe , sports cat headers exhaust and a remap , it cost 4000£ and gave 100 bhp extra which is a fair lump of bhp , my ls1 ute got mapped , it was difficult to notice much of a difference , diff in my monaro a big improvement

The price quotes were for the 2 different jobs, AAS for the exhaust as I've already got cat back. The Walkinshaw was for intake and remapBasically start withe the intake first then a cat back followed by the headers.

There is no such thing as BHP, it is only a mathematical function of torque.
What you really want is to be able to apply more torque to the wheel per unit of time.
PH’ers should know this! I came to this forum hoping for a better quality of post than BarryBoys or Facebook, and some of it is, but a lot of it is equally uninformed dross that someone heard off their mate down the pub.
Alas!
