H-Pipe Not Meeting Expectations

[GreenS550]

The suitcase is actually an X pipe with holes in it. But, also a covering. I am thinking an H pipe with the vibrant 12" resonators might just do the trick.

My '18 is too noisy for me and I suppose it might be due to the sound tube and/or the blower

lol Maybe it's the wind noise from all that extra HP!

Actually the suitcase is just two straight pipes with perforations, not an X or an H. There’s no connection between the two sides in the suitcase.

Has anyone installed a H Pipe in front of the existing suitcase resonator?
Seems to me this would provide a deeper exhaust tone whilst keeping the whole system from being overly noisy on start up and when your into it.

There is room in front of the resonator to weld in a small H pipe, it would be inexpensive to do and easy to remove if need be.

My error. My memory isn't what it used to be. I distinctly remember looking right through one and it is actually as you stated. Good grief.

The first time I peeked inside I thought it was an H pipe too. It’s hard to tell that theres no crossover connection.

The H makes for a great sound. But for some of us old guys, too loud. A lifetime ago a good friend working at Eaton made a beautiful H pipe for my 1964 Galaxie with a stroked 427. I put high flow turbo mufflers on it and the sound is simply unattainable with the Coyote. Incredible and the exhaust pressure. Amazing.

I have the active exhaust on my '20. I had an h-pipe installed and did not care for the rasp and general tone what-so-ever. I had that removed and had it replaced with a Magnaflow Tru-X resonated x-pipe. While the tone is just what I wanted (deeper and much more refined) the volume is just a bit louder than the stock resonator.

Wonder how it would sound with the Tru-X resonator left in place and then performing a muffler delete............hmmmmmm.

I ran a Tru-X for a while with the stock 2018 non-active mufflers and didn't care for it because I thought it actually decreased the volume a little in higher rpms, and also felt like it restricted the power a tiny bit. This could have all been in my head of course but that's why I got rid of it. Maybe it's different with the active exhaust, have you noticed anything like this?

Under load/acceleration the car sounds great. While under steady cruising throttle it's pretty quiet but I have not heard it outside the car. I'm afraid the car would drone with leaving the resonator in place and doing a muffler delete kit.

As far as any decrease in power via the good 'ol butt dyno......never really felt a difference.

One of my favorite videos on the benefits (or lack thereof) of X and H pipes:

I personally think it needs some muffler. I saw a video with Roush mufflers and a TruX that sounded fantastic. I’ll have to find that one. IMO the Roush are a little too wild with a normal H or X pipe, but with the MF TruX it tames it down just enough and gives a nice growl.

Just installed a Steeda H-Pipe on my 2020 GT Convertible with active exhaust.
I was expecting a slight increase in volume, keeping the deep tone, no rasp, and no drone. I've got the total opposite.

Volume: The start-up volume is extremely loud. Too loud for what I was looking for.
Rasp: I find that when getting above 2500k RPM the tone is much raspier than with the stock resonator.
Drone: The drone inside the car is ridiculous, especially in 9th/10th gear on the highway which I'm thinking may be because it's a convertible and not a coupe as the videos I watched said there's no drone at all. Even with the stock exhaust there was some drone in track mode in 9th/10th, so I'm thinking it's a convertible thing. But the drone at all speeds now is a lot.

My goal: To reduce overall volume a little, and get back to a deeper tone without the rasp.
Considering a few things and looking for input.
1) Cut the H-Pipe between the H and the Steeda bracket (shown in the picture) and Install 12" Vibrant Resonators?
2) Go back to stock resonator and do nothing
3) Go back to stock resonator and spend a ton on an axle-back active exhaust.

Thoughts?
