Just ordered a 3.5 inch downpipe and I would like to know your opinions on what to do for the exhaust system. I am currently running the hooker cat back system and I am very happy with it. As most already know it has a 3 inch collector that bolts to the test pipe. Should I find a 3.5 to 3 inch reducer and fabricate the connection to the test pipe? Or should I try to find a 3.5 cat back system. Is there anyone out there that makes these? Thanks for your help!
