Has anyone used the SSI for a SWB car? I bought a set from Ecklers(deleted them from my world because customer service doesn't exist) and the center support tab on the right side was welded on upside down and ALL the exhaust ports were uneven and not machined properly. Called the manufacture as well....sent me back to Ecklers. Just wasn't mentally prepared to take on customizing new SSI heat exchangers. I don't like to complain but when customer service doesn't even care, I feel like I need to tell someone.
