To fit the SZ turbo outlet pipes you need BDE low profile mounts or OEM AL bracket needs to be notched. Not worth it unless engine pull is scheduled, IMHO. As for the intercooler piping; I found the hardest part was removing the oem piping, install of the 2.5 piping and intercoolers was cake walk and well worth it. Took me about a full day, that included modding the corner markers to fit intercoolers.
