Did you get the regular ss one or did you get the coated one? I think the coating does help with the heat, although I like the look of the regular ss better....
I think the all stock intake is best, I just added the Takeda for the sound. Also with the RV6 there is a lot of heat since there is no more heat shielding. I've been looking at a Perrin down pipe blanket made for Subaru's and it looks like it will fit just need to add a hole for the 02, but 200 bucks is a lot. I might just header wrap it.
