Straight Pipe Exhaust help
I have a 99 1500 5.9 and I have an open exhaust from the cat back. I'd say go with option number one. I continually get asked if my truck is a diesel because it "sounds" like one. It's loud, and yes, it pops and crackles but usually just on startup.
I personally don't think it sounds like one, but that's probably because my fiance owns one.

Right now, because the muffler is cut off, the pipe from the cat ends right under the cab, and I didn't know if the vibration was just because the pipe ended there, or if this is normal.
Thanks again!
Cool, that's exactly how I want it. However, do you get a lot of cab vibration from it, almost like a subwoofer "bass" tone?

I love the way it sounds, and right now, I really miss it. Don't get me wrong, the cummins motor sounds great, however, I miss mine.
If you are wanting good sound,but not the high pitched tone,3" pipe is what you want.Looking for the diesel sound?That would be hard to do without a diesel engine.With a gasoline engine,your only choices are quite,noticable,and loud!!!!!Another suggestion would be use 2" or 2-1/4" pipe,and a Magnaflow muffler,or Flowmaster 50 HD....The smaller pipe would give you more punch through the muffler..Just a thought!!!!!!
