I believe it.

The Nissan 350-370 crowd have been running them for years and they have a few aftermarket applications tailored with branch resonators.

I am not sure why a tuner hasnt stepped up to produce these for our cars. Something designed with carefully calculated sizes and lenghts (no offense to your math skills )

Folks seem intent on welding straight through resonators in the Xpipe but branch resonators in the rear section is what really eliminates drone.
