Recommended exhaust shops in orange county

[alexc0814]

Hello,

I'm looking to do the fister mod to my exhaust but since the car is my daily I need it to be a single day type thing, and it seems like any decent muffler shop should be able to replicate the mod (for hopefully less money too). Something around orange county would be preferred but I could travel to san diego or LA too for a good deal.

Thanks!
