Just bought a k03s :-) advice?

larger bore decat downpipe will make a difference even with the rest of exhaust as standard - well worth doing

stick with grooved discs as drilled seem to have a tendency to crack easily from past expereience

Resonated is the quiet one

When you say how hard is it -
I took my K03s off yesterday as its shot and needs a rebuild - I started at 7:30am and finished at 11:30am, its fiddly as hell and you end up switching from under the car to over the car all the time lol

Worth it when its all sorted though 

In regards to upgrades, just look at peoples sigs and go as far as you want...

I have grooved disks. They realy good and aint cracked.
fmic is worth is all the way. If you want a better induction kit then get one thats a cold air kit (sits right at the bottom) but be carefull in wet weather as your engine will nock the water back.
also for non resonated systems, cops wont say jack to you AS LONG AS YOU DONT FLOOR IT PAST THEM lol
my mk3 is loud and drowny as anything but i only use it 1 off and never floor it to hear that throaty beefed up noise from the back

[Dalo Harkin]

Unless it states not for road use, there shouldn't be a problem with the amount of noise

Louder is better

I've been looking at the fmic u get on eBay for around the 200 mark, but read good and bad reviews :-/

I run an eBay FMIC on my MK3 conversion and it does the job perfectly. I don't think you'll be running the power on a K03s that requires huge Forge intercoolers. I'd say buy the core seperate though and route your own pipes and I had to throw out a lot of the kit 

[Dalo Harkin]

If your stage 2 on a K03s you need an FMIC, what limits the ebay FMIC is the diameter of the tubing you need to be above 2" (preferably 2.5") for it to be worthwhile fitting one
