Gt exhaust on ecoboost?

[gigo980]

Im thinking of installing a quad tip exhaust on my ecoboost and i was wondering if the gt exhaust would sound better than an ecoboost exhaust if i adapted it with a y pipe?
(Looking for the deepest tone possible)
If you have any suggestions on good quad tip exhausts for the ecoboost then please tell me.
Thanks!

4 won't fit in the diffuser hole you have now. Afaik there is no difference from behind the y pipe 8n chamber or packing.

I've considered the same swap, not for sound, but for performance. I've been told that the GT pipes are 2.5" instead of 2.25". If you're picking them up at a salvage yard, perhaps you can also pick up a GT rear diffuser!??

An I4 will always sound like an I4, no matter how many tips the exhaust has. Is this just for looks, or what are you after with this mod?

Ditto! Only thing I can figure is that it's a generation thing... At the track I run a single drag pipe (which to me sounds like a honda civic without exhaust), but while warming my drag radial tires up in the burn out box, I sometimes get a thumbs up from the younger guys!?
Reminds me of when my Grandmother told me my 390GT Mustang sounded like a truck...lol

I'm running a 3" downpipe into a short Y adapter into the GT catback without the stock resonator, and this is what it sounds like: https://youtube.com/shorts/j78nD5zcZWk

From the inside, it's fairly quite. As for performance, that's hard to gauge as before this setup I had straight through mufflers.

Did the short y adapter cause any problems with the fitment?

No issues with fitment as this was a custom job. I'll get some pictures once I have the car on stands sometime in the newest future.

The exhaust is mostly the same between them, and an Ecoboost will pick up exactly no horsepower from the cat back exhaust. The downpipe can affect spool time but that's about it. The sound will always be that of a turbo 4. If you want a lower tone, look to an aftermarket cat back that has a resonator. They tend to accentuate the low tones more.

Try the MBRP race series for your car. It gives an aggressive tone and arguably the best sounding sporty exhaust for the I4. MBRP 2015-2021 Mustang 2.3L Ecoboost Aluminized Race Series Cat-Back (Polished Tips) - S7275AL If you have any questions please feel free to reach out to me. #TEAMLETHAL
