I just installed the Sinister kit on mine. I can tell you that the blocker plate fir like a glove with no trouble getting both of the bolts in that support the up pipe, but no slack.
I paid the extra for the Sinister kit because of horror stories I read about Rudy's and other less expensive copy cat kits having difficulty getting all the holes to line up. This caused the bellows on the stock up-pipe to rupture, necessitating doing it all again.
Personally I don't like the idea of having to re-do work that I don't have to, because it is not fun and ultimately even more costly.
I think you get what you pay for, you be the judge.
