Has anyone tried putting a different exhaust on their bronco? I have the 2.7 V6 twin turbo and been wondering if borla or corsla and have they noticed any mpg change

Lots of reviews for both of those on here.
Checkout “Fast Intentions” too.

I have the @Fast Intentions Inc. & have been very happy. Mileage, couldn't really tell you, but it lowers temps and creates more torque & hp without obnoxious exhaust notes.

Probably the best way is to monitor boost or engine vacuum on a certain stretch of freeway at a constant speed. Take several readings before changing. Then compare after you install the new exhaust.

I don't know if the Bronco gauge will read vacuum or not. Most accurate would be to install a temporary analog boost/vacuum gauge. Tee off one of the lines connecting to the intake manifold. The lower the boost or higher the vacuum the more efficient the engine.

I gained around 4 inches of vacuum when I changed the muffler on my WRX. I went from zero to 4 inches of vacuum at a constant 70 mph. The company selling the muffler claimed 7 hp.

If the new exhaust is working for you, your Bronco may even feel a bit more responsive. But the change is subtle.

Or you can spend the money and pay someone who has a chassis dyno. But make sure you use the same dyno each time.

I have the 2.7 and went with the Borla S-Type exhaust. Did it for looks, sound, and higher clearance. If I got any more MPG it’s nominal. I am getting a bit better gas mileage though with my Pedal Commander.

@Dadsquatch how does the s type sound to you

@Brandon113 I think it sounds great, but I’m not an exhaust expert. The ATAK will definitely be too loud and the Touring I was afraid wouldn’t be enough. The S-Type seems right to me. It’s very loud on initial startup while the engine revs until warm, then has a nice low rumble at idle. When you step on it, it’s noticeable from inside the cab and you hear it but not annoying by any means.
