Honestly, I probably would have posted something here and asked if anyone with a lift installed a Banks exhaust kit and if they did, how did they solve the clearance problem. If I got decent feedback, like I did in this case, then yes I would have bought it. If I didn't get any response, then I wouldn't have bought it.
Now having written that, I should have done exactly what I just wrote and then I would have been prepared and avoided this issue altogether.
As Homer Simpson once said, "I am so smart! I am so smart! S-M-R-T! I mean S-M-R-T!
