I have thought of the down pipe thing and if I am replacing parts which I know I will be I am going to do the 3" down pipe but I may change the whole exhaust system as what is the point of having a 3" go to a 2.5" and back to a 3" tip I don't know why magnaflow did that instead of going 3" all the way maybe noise reduction who knows seems like they made more work for everyone there....Thanks for the reply.
