I am looking for some of the stock 2 3/4" rubber hoses that come on the stock 4tecs like the exhaust and intercooler hoses. I am trying to route my exhaust out the back (thru hull) without taking off the opas or relocating the stock RXPX intercooler. I would like to use the Riva Rear exhaust aluminum tube but I'm not sure if I can make it work without moving the intercooler. I'm in south FL if anyone has any of this stuff or any ideas on what to use to run a rear exhaust on an PX without removing the opas and moving the intercooler I am open to ideas. I wouldn't mind trying the riva waterbox if anyone has one.
