I need help on my next mods. what route I should go. As of now I have only the Y-Pipe and rear mufflers installed. I have the exhaust but not installed, and the vcn is not either. I want to really open up the breathing first.

I'm gonna order the large K+N, make my own heat shield and custom CAI. i'm also really considering having the uim/lim PnP

Any Suggestions on my next mods before I install the N20 and full exhaust?

With just a y-pipe i put down 164whp/147wtq

How can i get to around 180's whp/160's wtq


Thanks in advance
