That sucks I have installed tons of boom tubes and never had a alignment problem.

So....I had to bend the sh*t out of the hangers. It looks perfect now but required multiple installations and removals to get them bent just right.

Dealing with the poor fitment was worth it once I got the hangers bent right. The exhaust note is the best out of all the systems I have tried (5 to date)!
