Took my 95 F 350 duelly into the shop Monday morning to have the Bellowed uppipe kit and 4" diamondEye Turbo back installed. From everything I've read on here and, I had one person tell me he could install the uppipe kit in about 3 hours, I was thinking it would be a two day job to complete all. This is the third day and it's still being worked on but, after calling again this morning, I was told I will have it back today but thought they had all week to complete. DiamondEye is to blame a little bit. They advertized old out new in. Only they don't tell you there's a lot of cutting and piecing together to get the new in.
