Scotty's are Simply a work of art. I'm currently using a Pod but got him to make a pipe to fit stock box. It accomodates either very nicely.
Not hard to cut the Breather and Bov pipes to install. Sounds all wooshy and stuff with a Pod. Very nice.
In Fact, the pic above is MY PIPE! Photo taken in the Backyard after painting.
Forget buying a metal pipe for sound though, Buy one to ensure your intake can NEVER Suck Shut!
Plus it looks totally tits and sounds sick.
