Simple exhaust question!!
Just put a Flowmaster 50 SUV series on my truck. They did not have the size I was looking for. All they had in SI/DO was 2.5"/2.5". I have a 4.6L, will this affect backpressure more than a SI/DO of 2.5"/2.25". Also down the road would it be safe to run a SI/DO of 2.5"/2" and bring it up to 2.25" pipe using a reducer coupling backwards. Thanks for any help.
