It seems the Raptor guys are unhappy with the oddball sound of the twin turbo ecoboost 6 cylinder, even though it has lots of power and is a technical marvel. I bet they grit their teeth when they hear a Rebel (or other cool Ram) go by with an aftermarket exhaust rumbling the Hemi power sound. Most Raptors probably never see real Baja type off roading anyway unless they live in desert states. I bet more will switch to Rebel in future.
Isn't there a rumor that Ford will be putting their next big V8 in the Raptor? Likely around the same time the Rebel TRX comes out along with an actual V8 in it.
There isn't an exhaust on the market that can fix the sound of the Raptor.
It's an incredibly underwhelming sound for a $75,000 baby-baja truck.
Yes, the tech specs are good, but Ford is capable of building a NA V8 close to those specs, they won't because they're trying to sell ecoboosts to their regular truck buyers due to the EPA CAFE situation.
To do that they're convincing Ford buyers that the ecoboost is literally the best engine ever, and there are no alternatives - by putting into their top end vehicles (Like the GT, and the Raptor).
It's working, there's a near religious following for the ecoboost on a ton of web boards.
The arguments go as far as to suggest that NA V8s are actually more complex than the the V6 turbo with intercooler setup.
