Speed Engineering True Dual X Pipe Side Exit
Here’s a video of my 2014 crew cab with the Speed Engineering X pipe exhaust that uses the rear side exit. I originally had the y pipe and 3.5” exhaust into a Borla XR1 that was dumped at the rear axle. Sounded great but drone was so bad I had to shift into 5th on highway to fight the drone with any normal conversation I had in the truck. This new exhaust literally has 0 drone at any speed and is mild outside, but once you go WOT it gets rowdy. From driving it roughly a week I believe I picked up power also. I will also attach a video of a WOT i did with the windows down. Instal was awesome. I did use lap joint clamps for driver, passenger, and crossover connections. I believe you should use some ultra copper RTV on the crossover with a clamp or weld or v-band since the curve of the attachment from driver side header makes it too hard for a perfect seal. I used the supplied clamps for the rest of the connections you just have to tighten them down until the clamp is touching. I used an air gun then ratcheted the rest of the way. It sucked.. but no leaks!

Nice. Think I'll add that to my Christmas list.
Gotta ask, who tuned the truck? Reason I ask is mine hits 5500 in first and feels like it hits a limiter and stalls for a second or so before it shifts.

I used a guy local to me. i’m in OKC. Man I see you mention the drone and you need to give this a shot. $475 shipped to my door from a dealer. true stainless. can’t beat it. Are you saying mine runs good? Lol it does need a slight tweak in tune after exhaust. Shift points on normal driving is little off but overall I love this and in my opinion, screw a $1000+ Corsa catback

I’m willing to bet that hitch is still some torque management. I remember you said you were using a mail order style tuner. What’s your overall impression of that L86 manifold? That, and a little bit of opening up the stock air box is next before a retune

I'll grab a video later today. I'm betting it's torque management also. I'm debating picking up HP Tuners and getting it tuned locally with that instead of the Diablo.
Can't say how much the L86 improved anything as I don't have any before and after numbers but the throttle response was certainly better. Mileage stayed the same.

Thanks man. After driving a little more I *think* it's a tad louder on E85, but not obnoxious and I like it. Which would make sense though since truck makes good amount of power on E-85 over 91. Love it so far
