First option:
1. All available product for Saga FLX (accept Room Bar) from Ultra Racing.
2. 15" rims with 195/50/R15 tyres.
4. ECU tuning, remove speed limit and improve FC.
3. Aftermarket high flow stock replacement air filters for Saga FLX.
5. Aftermarket high quality or braided stainless steel brake hoses.
6. Aftermarket Rear skirt diffuser.
7. Aftermarket 4-2-1 exhaust manifold with ceramic coating, keep stock catalytic.
8. Aftermarket S-flow muffler.
all 8 options seems good, and yes do keep the stock cat-con on so you don't compromise the environment unnecessarily
if i may recommend:
- get good brake pads such as EBC ultimax/greenstuff (if more braking power is desired along with low brake dust/noise) brake pads
- get good engine oil (eg: torco, liqui moly, motul)
- get good CVT fluid (eg: lubegard/torco/motul)
- get good performance oriented tires (NVH will be a concern though, consider 2 sets of tires if you want both)
- get good lightweight rims, japan oem'd tech such as advanti, lenso would be good, if budget permits can go higher such as original japanese rims
- get good suspensions, adjustable if budget permits (at least 2-3k or more for the good ones) or get good progressive based sport springs such as eibach or H&R along with good absorbers (consider sport/performance based gas types as you're going for lowered springs (good ones only lower a bit so not much to worry) and it'll stress the absorber more than stock springs
- stick with 4-2-1 + s flow, and try to go for proven reputable brand while at the same time leaving the stock cat-con
