I have a 3" exhaust the HKS super dragger is 3" all the way to the tip and it is a 5" also I have taken out my cat and installed a test pipe so it is straight through. Thus with my 1JZ it isnt that loud really at idle it has a rumble to zib clothes other than that nothing. My n/a 7M was actually louder.
