S475 / S480

Yeah, I was thinking 3" max or maybe a larger oval pipe. I found another build by junior636 he had a bullseye s475 t4 but ended up selling it before finishing the build. The compressor cover looks different/smaller than the others that I have seen. I need to call them and see what is up with their s475. It looks like it should be doable. I believe the shortest filter that will fit is 6". Here are some photos that stole from his build.
