Hi all. I finally cut my OEM mufflers out and had stainless 'Resonators' put in their place. Also removed the OEM resonated tips and replaced with Megs res-delete tips. The exhaust is WAYYYYY louder than I expected, and was promised, it would be. Very raspy. Anyway, the car seems to be running way more fat, especially on the big end. I have A/F ratios of 10.4, where 11.2 was the norm.

I smell fuel all the time, from idle to ripper. burns my eyes and face. I would have thought an open exhaust would lean me out a bit, but I'm pretty fat.

In summary I am Trilogy kit 224, Kooks Headers into X pipe. Air intake. Lightening MAF. Exhaust is 2.5" everywhere except over the axles is 2.25"

Not sure if this should be in the tuning section, but will start here. Really wish I was close to one of our prime tuners.

I think I can data log, but my old Xcal 3 has a bad LCD screen and I cannot see it most of the time.

Any insight out there?

The resonators aren't going to cut the loudness, they will help eliminate some drone. 18" Magnaflow mufflers will help cut down on the loudness.

Maybe contact MartyO, his guy Jeff is a tuning wizard.

If you decide you want a re-tune, talk to Marty. You can remote tune with them and datalog with your X3 plugged into your laptop. They will log into your laptop and set it up for you. Just follow their direction and the process goes really smooth.
