bolt-on

I have Ktuner, Bolt on aFe CAI, aFe SS Catted DP, aFe SS Front/midpipe, Full aFe SS Cat-back dual exhuast, Im still debating Misimoto vs PRL for intercooler, I need tires, Ive been staring at the 27won RMM for a quick minute, after that besides a drop in turbo, what else can I do?

Just placed my order for aFe power's Full bolt ons, Takeda Momentum Cold Air Intake System w/Pro 5R Filter Media Takeda 2-1/2" to 2-1/4" 304 Stainless Steel Cat-Back Dual-Exit Exhaust System Twisted Steel 2-1/2" Rear Down-Pipe/Mid-Pipe Twisted Steel Down-Pipe (Street Series) Will update you...

K-Tuned has released a downpipe for the type-r, fully built on with no tune need and no check engine light. What do you guy .
