Ok so I am still in high school and we have to do a senior project and I am working on my car cause I want to lean more about them and how to work on them. I have a few questions though I am looking at buy the Blitz Nur Spec R catback for my car and i want to know if I get that should I but a Cobb accessport? I was reading and it seams that when people get exhaust they seam to recamend buying one or you have to. Even if I dont need one and I do get one would it help with HP or would it not be worth it.

This could be a noob question but what makes the car stage 2? Is it when you do the up pipe and down pipe?

Thanks guys help would be appreciated

 

am running stage 2 with HKS up pipe , HKS downpipe, HKS Carbon Ti exhaust. intake nd underdriive pulley with COBB AP flashed to Stage 2 map. That's wat makes the car stage 2 or as i know off

 

pretty much just a dp makes it stage 2. if you can swing it, get an ap for your exhaust, you'll love stage 1.

 

ok thanks guys yea i am going to get an ap thanks for the help
