So I got ambitious and did a Vacuum line/emissions delete on my late 2g DSM.
The engine bay looks much cleaner that before, only other thing I really need to do to clean up the engine bay is swap out my throttle body and intake manifold
Before removal:
After removal:
If there are any DSMer's wanting to do this be warned that doing this will render your car illegal on Federal highways, but if you've removed your Cat, then it's safe to assume you don't care about it
also here is a link about which lines you can remove, whatever you do do not t you BOV line like it shows. this has been proven to create problems with holding boost and getting correct readings
