I recently added a 5" Granatelli exhaust to my 7.3 idi turbo. I modified the downpipe to mate it to my application. Right after install I started the truck and she fired right up like she always did. Now, it's taking about 4-5 tries to get her to fire, and even then sometimes it'll just choke out and have to try again. Once it starts it runs fine and once it's warmed up, it'll start right back up first try. Any ideas? It's very troubling. Can't understand why adding an exhaust would make my truck hard to start. Thanks in advance for any help you can offer.
