Three reasons to go with an aftermarket WRX up-pipe:
1: They don't have the restritive "flex" area that out legacy up pipes-have.
2: No cat as well.
3: EGT Sensors are good things. A aftermarket WRX up-pipe will already have
the bung in place for you to install one; no need to have it tapped.
Go with the aftermarket.
