does anyone know what the collector size on the dc 4-2-1 header. i have one on my ls and i want to know what size the collector is so i can get a high flow cat to match up. also i have a apexi rs exhaust and i have no clue what sized the pipping is.

 

search for the collector size.
get a measuring tape and measure your exhaust

 

The header collector is 2.00", and the exhaust piping should be 60mm or ~2.36".

Your best bet would be a 2.25" custom Carsound.
