Not sure of what or if they could do it but...
Oceana muffler on old vb blvd helped my out when I couldn't get the second part of my eisenmann axle back on. It took three of them an hour and cost me 80 incluiding my inspection. I was happy with the cost considering it took three professional an hour to do it on a lift, I would have never of gotten it.
They have done two f150's of mine which I was also happy with.
I also brought him my e36 m maybe 6 years ago, he threw it up on the lift brought me out there and told me he couldn't improve on the m's system. ( already 3 in w/o many bends). Which was nice rather than saying sure ill do it!
