I 4" down pipe will cause no issues...

Is the outlet a true 5" or just where it necks out at the down pipe connection?

Its not right in front of me, but I'm thinking since its the v-band outlet with a 88mm turbine wheel, its only 5" at the lip ends... If I remember correctly obspsd was having back pressure issues with running a 3"dp on his s475... Maybe he'll chime in...

I could see a 3" down pipe being an issue, but I really dont see a 4" being that much of an issue if any. More then likely its a 4" or 4.25" right at the wheel...

4" will fit. Take off insulation and beat it in a lil.

Gonna have to check them out later. I cut off a small piece of an up pipe to see how well it will fit around one of the flange opening. About a 1/4" bigger than it needs to be to fit perfect.

Any special bellows for the up pipes?

I bought the Irate kit and his has bellows.. If it were me and I was making my own I would def add some bellows, gives the up pipes just a bit more flex with the high heat.
