Hello everyone. Been a while. Last week I fixed my stupidity by removing my 2 year old Flowmaster set up to a Pypes set-up and everyone was correct...I'm so glad I did it. Here is my issue/concern. My car now takes a little longer to start up...but not too bad. Also, there is a hesitation when reving or during acceleration while warming up. I have never had this issue before. Should I worry? Would this be normal due to more flow or do I need to adjust something? Thanks for any input!
