Stock BOV and Pod filter will let everyone know its turboed if thats what worrys you
The only reason I have an aftermarket BOV is cause I was sick of the noise of the standard one. Mines plumback and doesnt sound to loud. The standard one just Shitted me off, but its a good item as anyone on here will confirm
Exhaust wise. I have an X-Force 3" turbo back exhaust, Mild steel $1100 two years ago when I got it. Stainless ones arent much more.
I like the sound of mine, wouldnt hesitate buying an X-Force exhaust again
