#1 I am a seafoam noob so don't know what it is and what it does and how to do it.
#2 Again, I know this sounds lame but I live in an apt, I have no where to work on my car quietly and without prying eyes from others. I can stop by a local exhaust shop and have them check for leaks, would they be able to see or find them should they be there or are they so small sometimes only seafoam will show them?
#3 Leaks would only solve some of the issues I am having. Being catless I am sure is one of them, the turbo xs, soon to be history is one of them as well. Going catpipe instead of trackpipe, might help but waiting for add'l suggestions.
