couple places i know of this is personal stuff ive had done at plaza muffler in orange. on lemon and chapman
theres pomeroys in santa ana just north of warner on main st. good work, good prices.
theres manny's muffler off harbor and the 22 fwy before trask. good work, 510 owner. lot of pride in craftmanship...he likes it to look clean under there. clean bends, welds.
ive done work on my personal cars with these guys and i have no problem sending my customer directly to them. if you go, tell em adrian from discount tire centers sent you...might help
