I ran off many leaks in joints and clamps when I went boosted + catless headers and Roush exhaust yet with the factory resonator!! it's still loud on wots but normal cruising is fine! However, Found an amazing deal on Ebay for an H pipe from Roush and couldn't resist the deal so I bought it knowing it won't be quiter but for sure I will have more somooth flow. I will not get rid of the factory resonator just in case the volum is unbearable.
it would be nice if we share the clips to compare set ups!
