Let me know what kind of custom exhaust work you are looking for, and I'll do my best to help you out.
I will be moving into a commercial space in the spring/early summer and would love to host an open house. Until then I am working out of my two-bay garage, which is adequate to get the job done, but can't fit a bunch of people.
In other news... Underdog Motorsports now carries a complete line of aftermarket parts for the Legacy, WRX/STI, and BRZ. I've attached a partial line card with the most relevant manufacturers, but if you don't see a particular manufacturer you are interested in, please don't hesitate to ask! As always, you can call, email, or PM with any questions or requests.
*edit* Updated line card and moved it to the first post.
