Cold Start - 2017-2020 Ford Raptor 3.5L EcoBoost Trombone Equal Length Resonator Delete, RDFR20EL

 Here's a cold start video of my Whipple Tuned 2017 Ford Raptor with the SPD Performance 3.5L  EcoBoost Trombone Equal Length Resonator Delete, RDFR20EL

Definitely louder on cold-startup than with the Flowmaster Flow-FX.  The truck sounds like a race car when you floor it, and really screams!  There is some drone from 1,800-2,200 rpm so I'm not happy with that as that is cruising RPM around town.

SPD Gen3+ Trombone Equal Length Resonator Delete Installed

 It's been 4 years since I changed the exhaust with the Flowmaster Flow FX setup and was looking for something a little different.  SPD created this new equal-length resonator delete pipe that mimics the 2020+ Raptor exhaust.  It's pretty funky looking!

When I first reached out in February, I asked SPD about "drone" and they said absolutely no drone... well, it's not entirely true.  

The pipe showed up a few weeks ago, so aboutI had mine installed today - ordered February, showed up about 2 weeks ago... almost 5 months waiting!!!

My initial review (sorry no video yet)

• The truck idles more deeply, and sounds throatier
• it's definitely LOUDER for sure, but very cool to hear how this engine 'breathes' - you can't hide any throttle wiggle with this pipe!  Seriously with this mod, it sounds more like you're driving a Ford GT - it's pretty crazy!
• sadly it drones around 2-2.1K rpms which is really disappointing, which is a lot of driving around town RPMs when in sport mode, and hunting right around 6th gear...

Maybe it's just the difference from the FlowFX which tended to rumble more in the middle of the truck - now all the sound has moved to the rear outlets...

I kept my Flowmaster FlowFX if I want to go back but will give it some time to wear in a bit

Hope to record and post a video soon for a better sound review.
