Hi all --
Planning the exhaust upgrade, and I'd like to get this nailed down.
Gibson uses 2.5" outs for the split rear catbacks for all engines. Is this
just a matter of standardization, or does it really not make much
difference?
I noticed Hoegen had a split-rear exhaust built with dual 2" outs for his
3.9, and I've seen others recommend 2-1/4". Anyone have any factual data
and/or recommendations on what's really at stake here performance-wise?
P.S. Hoegen, how much did the muffler shop charge you to do the exhaust?
TIA,
- Alex
