I have the meisterschaft exhaust on my e550. I love the sound. That said, I wouldn't mind a touch more volume. I believe an x pipe could achieve this. That said, I don't know if I would lose power due to the loss of backpressure, a trade off I don't want to make. Have any of the tuners or fellow members done a before and after and have factual and not theoretical dump results?

Thank you for your advise in advance! My car is going in to the shop while I go on a trip to have every don't removed, touch ups done, alignment, and might as well have them weld in the x pipe to be 100% ready for summer!! (If I will not lose power haha). I can't wait for the bumper to get the plate holes filled and touched up so I can finally mount my new front lip!
