Mornin' Y'all!
I just finished a one week trial of my straight pipe and resonator delete, and I have to say that straight pipe life is the only life for me.
I knew I would be happy with the sound, but there has been another, very surprising benefit. As we all know, there is a common perception that straight piping can reduce low end torque.
Let me preface this by saying this is only butt dyno results, but I've put 50k on the truck and am pretty familiar with how it feels and drives.
I'm pretty sure I actually gained a significant amount of torque from idle to around 2300 rpm. On my daily drive, which is around 110 miles round-trip, I've noticed the truck holding on to eight gear for a lot longer, and it actually doesn't skip down to 7th or 6th gear on moderate inclines. It just chooches right up the grade.
I have also noticed no decline in economy even though I'm getting into the throttle more from a dead stop and am running with mds off now that it is straight piped. I can only attribute this to a need for less throttle when cruising.
As most of us would expect, there was also a good top-end gain. There are a couple passing zones I frequently use to get around semis, one of which is a downhill stretch where it's fun to fly. Before straight pipe, I would be back in my lane at 80-ish mph. I have used the same passing zone twice in the last week, and have found myself hitting 95 mph when I'm finally back in my lane.
None of this is remotely scientific, I don't have any dyno numbers or 0-60 times before and after. I'm just a real guy giving my genuine perception. And my genuine perception is that everyone should be straight piped.
