I needed a section of 2.5" aluminum pipe welded to my stock throttle body elbow to complete my intercooler piping, lacking the equipment and skill to weld aluminum. I took the elbow over to CFP and Sean had the stock elbow cut off and a 2" section of 2.5od aluminum pipe welded on, and beaded the end for me. It only took him about 30 minutes after I popped in without much notice, and he only charged me 20 bucks including the pipe, which is better than I could find at several places. I give them "props" .
