I agree with the prior posts. My dealer installed my Specialty Spares exhausts, removed the AI, and put in the 130 mains. I ran it awhile like that but was having bad deceleration popping even after different adjustments. They THEN installed the 45 pilots that also came with the SS. The popping went away and it has run great ever since. The dealer had done quite a few of these changes and was very big on not going bigger than necessary or upping the pilots unless it proved to be necessary.
