Hi guys,

I can get a hiflowed s4 turbo for a good price, but would like the twin scroll s5 exhaust housing.

Can i just simply unbolt a series 5 exhaust housing and bolt it onto a series 4 turbo?
Are there any problems involved with this?

Also, are there any larger exhaust housings which would bolt straight up?

Thanks for the help guys,
Mike
