Im looking at putting a set of headers onto my 99 is200 that go into a 2.5 inch straight pipe with a sports muffler on the end and a high flow cat converter, I'm not sure will i need a tune after i do this exhaust or can i get the exhaust done and drive it for a few months then put a tune on the car? the headers do not have cat converters but still have the same factory, O2? sensors and the same with the new custom pipe.
Is 200 Straight Pipe And Tune? Help
