Speed engineering headers installed on my 2014 5.3
I just installed speed engineering 1 7/8 long tube headers, and off-road ypipe on my 2014 5.3 Sierra.
Fitment was great, and I’m beyong impressed with the sound.
Muffler is just a basic 14” maganflow on stock piping.
I am a dealer for SD if anyone one is interested in buying a set.
Heres a short sound clip of a blip of the throttle.

I installed a high flow cat on the end of the y pipe on my SE headers. I did it for the smell mainly. It didn't help the drone at all. Had to get rid of my Borla touring exhaust and go to a stock 6.2 exhaust to get it quiet.

i ditched my y pipe and single 3.5” exhaust with borla xr1 for speed engineering true dual exhaust kit with side exit over the weekend. mild but deep exhaust not, literally no drone, and sound wicked at WOT. I’ll upload some videos onto Youtube and make a thread tonight.

That's the literal first exhaust I had when I did the headers. 3.5" with the xr1. Sounded awesome but droned like crazy. Then I put my Borla touring back on. I swear it droned worse. I've been contemplating the true dual system from SE for some time now. Hearing it has no drone and will flow better and sound better makes me very interested.
