Installed reverse which is the Forge tech preferred method. Use the right spring, I am stage 2 so running 18-19 psi of boost, I used the yellow spring. I have this on my 9000 with stage 3 (atmospheric one), and they both work flawlessly and sound awesome. Of course the diverter design is less loud but you still hear it esp. with open air intake. I am running snorkel with K&N and I still hear it a little. It looks better in reverse also IMO. A no brainer if your old one is weak.
The kit comes with all the springs, lots of decals, tools, and cool keychain.
