Few questions. I just got my 4" MBRP exhaust kit. Just went to put it on to find that my turbo has a 5" coupler, and the down pipe I got is a 4" coupler. I cut my old exhaust out so now im screwd until I get the right exhaust. Is it ok to start my truck with NO exhaust on it. Right now its sitting in the middle of my shop, but dont want to start it to move it if it will damage something. Also truck is a early 04. paperwork that came with exhaust says its for a 03-04, so it should be the right kit. Are all early 04 turbo outlets 5"? Trying to figure out if they sent the wrong downpipe, or if I have a unusual turbo on my rig. Thanks.
