Remus: ???
Wagner: 3" or 4" available

I assume each of the 6 (although some don't have the exit sizing listed) will taper to 3" at the exhaust side to match the OEM exhaust.

What are your, and everyone's opinions on diameter piping?

This is my second consideration after pricing...
Cars with production date up to 08/13 have a flange size of 3.5"
Cars with prod date after 08/13 have a flange size of 4.0"

downpipe flange size have to match OE or else it will not fit
All companies offer both versions
