recommendations for exhaust

[Richard J. Andrews]

on my 4kq with relatively stock everything (except 2.3 cam and empty cat)
i left the middle muffler and had a cherrybomb turbo muffler installed at a
local muffler shop
the muffler only cost 19.99 and install was like $25.
sounds sweet but not too loud either.

i will record sound samples if desired.

HTH!
