Hi All, looking for some help with this project. After Googling and searching threads, most people do the resonator delete, and some sort of other exhaust modification, like secondary cat deletes. I am looking to be a bit more subtle for an '07 ML500, and don't want to cut off baby cats.
Initially, my intent was to add a resonated x-pipe, but based on a couple W164 underbody photos, I am not sure this is possible. The distance between both pipes is quite large and it would take some custom fabrication to make it work. Instead, people seem to delete the resonators before the rear muffler area and replace them with straight pipes. I am open to doing the same. A different thread said one can expect ~20% more sound with no drone and a quiet cabin off the throttle. That's exactly what I'm looking for ... something very subtle that'll add a touch more flavor to the exhaust.
Has anyone done a resonator delete? If so, what is the ID/OD and length of the piping you used? I would like to purchase stainless steel piping but need the dimensions first. Also, does anyone have any Youtube videos of the resonator delete only? I found one on a W164 and some older W210s, but if there is a forum member with something on hand, that would be cool to see. Again, most go beyond just deleting the resonator.
What's the distance between these two pipes?

Thank you very much! I took a look at the linked thread and this is exactly the kind of information I need. The vehicle has a few other issues that require attention including a nasty habit of eating a quart every 200 miles, so maybe an engine swap is in order. When that's underway, I suspect we may remove the resonators. Sounds great on throttle withouth the drone and other negative side effects.
