Tomei TI exhaust - does it fit S650 Ecoboost

[Stévens]

I bought the Tomei TI exhaust, I have a 2025 Mustang eco-boost, it was my understanding that it fit, but now I’m having trouble verifying this. Could someone help me please?

Not sure, but one datapoint is that S550 Ecoboosts had 2.25" exhaust pipe diameter, and now I believe S650 Ecoboosts have 2.5" diameter (like the GT).

This means GT axle-back exhausts (your item looks like an axle-back?) fit the S650 Ecoboosts, as proven by Roush listing their S650 axle-back as the one item for both Ecoboosts and GTs.

There are several after-market exhaust systems out there for the EC, and no two alike. But this one? It is the loudest, raunchiest one available! I guess that's why you ordered it?

It is a Cat-Back system designed for the S550 Ecoboost

i definitely like the way this exhaust sounds the best but now I’m not sure if it will fit

My experience with that exhaust on my Subaru Sti is two years in exhaust started leaking via the slip joints and finally the weld where the curves are started leaking too.
