His harpipe kit were one piece...it was very nice! Except the BOV was positioned weird...
DSMconvert stuff has always been way cheaper then its competators so I dont think matching it Perrin is even an option. I dont think hes using aluminum or the price would be high.
I would say a nice SMIC to match your Hardpipe kit (best option for fairly stock turbo). And maybe a trade in or upgrade program for a FMIC. Meaning trade in our old pipes for a FMIC. And then you can probally sell the returned pipes for a fraction of the price. Just a suggestion. Im sure for stock set up peopel will buy a SMIC and the future they might consider a FMIC with a bigger turbo.
