Dumbrotorkid

If there was something wrong with the secondary turbo Is there any way it would make a noise like a hitting or knocking sound?? because i was driving today and ive had this ticking noise for a little while now and it used to be at regular intervals(ticking) but now every once and a while it skips. Im aslo hearing the turbos whine alot more now that i put the stock main cat back in. Any ideas would be helpfull thanks
