Sometimes the dealership themselves don't make the call. When my front lift failed my local guys had to file EVERYTHING with PAG Germany to effect a warranty claim. That included every single mod on the car. You'd bet there's somebody in Zuffenhausen whose job is to review that data and determine if the claim is eligible under warranty... It's unfortunate but that's just the commercial reality. You and I might do the same if it's our business.

My advice is, if the warranty is important to you, don't mess with the exhaust. Or at the minimum, have the upgrade done by a trusted independent and be prepared to swap out everything for original parts if/when you need warranty work performed...

Similarly the modestly stronger pull above is likely just perceived, but the combination of weight loss and slight torque improvement (perhaps) in usable range makes it a winner.

My car has no A/C, lightweight exhaust, lighter Euro bumper bar, and Wevo motor mounts so I have approx. 92 lbs. off the rear of the car.

What I was wondering was whether it was a drastic loss or a small loss. I know you don't stay below 3,200 RPMs for long but there are times and you don't have the time to downshift...
