anyone try this a-body 383 big block exhaust

i bought the 340 system with the stock mufflers.I tweaked one spot and the fit was o.k. right to the stock manifolds.
the stock mufflers are very quiet..but that was what i was after.I love the sound of the
unsilenced air cleaner moaning at wot.
i think my system was on sale for $288 complete with mufflers..Such a Deal!
