Hmm i recommend getting AEM cai instead of INJEN cai unless you can get a replacement for their retarded washer bottle. Other than that, AEM and INJEN are pretty much the same in term of improvement over stock intake. For CBE system, if you going for good budget and light weight, I'd say STILLEN is good, but with a few added lbs, you can get MAGNAFLOW instead. MAG's tips are very nice looking on the GC since they have the biggest tips out there compare to others. If you're looking to drop the car to 1 pinky gap or lower, then ARK TD Exhaust is not recommended

. You can ask qwaszx for his opinion since he saw how scraped up on parts of my ARK's.
As for the talk about ARK's CBE product, it's up to you to decide (if this is what you're looking into). For me it's great, just having issue going big bumps.
You can also get PowerAxel (sp?) reflash or SFR reflash (which I got). Not sure about PA Reflash since I never got that one, but for SFR's, it is also great for me too, plus it was worth the drive up to PA Westchester.
For suspension, I have Stance GR+ which is great, you can go with BC coils too if you're looking for budget cut. Ark Dtp is also good as well, but that's just from other members' words.
If you drive around Chantilly area a lot you'll most likely to find me driving up and down 50

. If it's a dirty Nordsgrey with no badges and a scrape on passenger side, then that's me
