So far I have not heard from big to small. Most have them of equal size all the way. Only heard from one of my turbo friend with modded engine, from 2.5" all the way the near rear end go to 3". Even my turbo is 2.5" all the way. NA depending on CC can be from 2" to 2.2"......:rolleyes:
I think is pretty common now for turbos to go from big to small. I have seen a turbo car went from 3" at downpipe, to 2.75" middle piping and 2.5" muffler...... 3">2.75">2.5".....
But i myself use 2.5" all the way la....and the muffler is called a Loop Flow....Not S-Flow....Something the exhaust shop fella came up with.....
