I wonder if that guy who is selling them would trade. My boom tubes arent loud enough...

 

Got them installed today, sounded better than I expected. There's a second at start-up thats actually really loud, but it tames down fast. Bits of drone here and there but nothing I didn't expect, with what's basically a muffler delete. Definitely glad I pulled the trigger, though!

Finally installed mine today too. Different sound than the flowmasters. Not as throaty.

 

They do sound pretty dam good.
