I have gone to 3 different shops for work already. The work is OK but hard to recommend, especially on lowered cars and for picky Lexus people.
The one several of us trust is Troy Ermish Racing in Fremont.
Good if you need a whole custom exhaust done.
Do a search for Ermish in the NorCal section for history.
For smaller work I am trying out another shop for some small work this week. I'll post once I have results.
If the place checks out I may consider them for installing my x-pipe and running custom piping to eliminate my resonators.
I'd go to Troy Ermish but he is only open M-F until 5pm, which never seems to work for me.
