so one question I have is Valvetronic said to use a 2.5” x pipe which I did. The actual pipe on the ford is 2.25” so the muffler shop made an adapter to go from the stock pipe to the x pipe. Should I go with a 2.25” x pipe ? Wasn’t sure if the pressure was building up in the x pipe. Just one more thing im throwing out there.

Valvetronic Exhaust

They will just use a reducer, it should be fine. It's not as if ur car is going for a 3 inch to a 2 inch.
The other question for you was what rpm and speeds did it drone?
When I had the mrt axleback on the drone was bad between 2500-3500 rpm
And between the transmission sitting in higher gears and the drone it became a nuisance.

The best exhaust I have seen so far....

Someone was saying that without an x-pipe, the valvetronic mufflers can sound a little raspy. But I also heard in this thread that people are also getting drone with their exhaust setup which would be upsetting to have.
Another thing I am curious on is about using an x-pipe or an h-pipe since I hear an h-pipe can deepen the sound of exhaust. I wonder what I would like more since I normally am a v8 sound kind of person but since this has a v6, maybe just support that sound with an x-pipe instead of trying to morph it closer to a v8 and miss it by a mile. So many thoughts!!!
That looks like a sweet setup! I assume it's more effort and money than I would want to get into right now but I'll dream about it!

I would agree with that statement because hopefully if they're wrong, they'll work with you if there are any issues.
Issue here is this is a thread about the Valvetronic mufflers that are universal so they will not guarantee it will be drone free. So what I and everyone else on this thread are trying to do is see if others have installed these mufflers, if they had any issues, and what they may have done to resolve those issues.

The "drone" sound is entirely based on the acoustics of the exhaust- which if you're not an expert- you don't know anything about. No single muffler or cross pipe is the problem. It's the volume and length of the exhaust and the pulses per time (frequency), which produce the sound.
Trying to guess which hybrid solution will work is pointless! If you do a hybrid solution and get lucky, cool. Otherwise, you're going to have to invest in additional acoustical aids (Helmholtz resonators) to cure the resonance at low RPM frequencies.
If you think the ST is ever going to sound like a true dual-exhaust cross-plane V-8, you are bound to be disappointed.

Just looking for people's experiences. There are always people willing to do some experiments for the fun of it and FOR SCIENCE. I used to do this with a friend when I was in high school and college where we would throw together random exhaust systems and tell people about it in forums and people found it interesting and at times beneficial. I no longer do that but am just seeing if anyone else has tried such a thing. It seems there are a few people trying it such as 56mq and WindyDishes and just looking to see what their experience was.
