Yup, I agree with Barca. I have the 5.5 V8 and initially went with an X pipe, then went to straight pipes. The note is definitely quieter with the X pipe, but doesn't have such a "chug chug" leaky noise with the straight pipes. When I get to it, I'll probably put the X back in (but it doesn't bother me THAT much to immediately make the switch back). I do really enjoy the louder note at WOT that the straights provide.
My next mod is going to be KW Street Comforts to improve the stance.

Tough to say but I would guess ~25% louder, but with a more noticeable rumble. I'm now interested in the sound without the bulb resonators, which I've never touched.

Oh so you have just the rear set of resonators removed? I wonder how it would sound straight pipe all the way to the mufflers with both set of resonators removed.. Vs my set up which is X pipe to straight pipe to mufflers

I had the exact same set up as you but wanted to try it without the X-pipe. For the most part I'm happy, but may get around to either removing the the bulbs or replacing with high flow cats.

Just replaced the x pipe with straight pipes and I like the sound a lot more now. It has that raspy farty amg noise to it. Thanks for the tip. However I did unfortunately get a fat speeding ticket from testing out how the new exhaust sounds. O well.

Does anyone who has removed the resonator's have any pictures of the layout inside of them? Not cut open but just looking through the pipes from one end. I am particularly interested in whether then large centre resonator has any form of cross over or x-pipe arrangement inside or is a simply pair of straight through perforated pipes.

Thanks. So the pressure equalisation is no more than that shared within the chamber. It makes me wonder if a kiss pipe or arrangement like Supersprint use might be a good compromise between the very quiet x-pipe and thumpy straight pipes. It might also prevent the mild torque loss than some people think the x-pipe creates. Thanks for your help.

why wouldnt you pass visual inspection? The two sets of resonators are just that? Do you have that exhaust leak sound/noise everyone talks about from the rear of the car when they go straight pipe? I'd love to hear your setup!

In my experience, 2.5 inch ID X-pipe gives the best performance, noticeable torque and mid gains. Straight pipes are louder but feels very similar to when the standard resonator is still in place. I've never tried an H-pipe. However, I shall be putting on my C63 cat back exhaust system on my 550, with a centre resonator that is a bit of an H-pipe

Whatever you do, don't do a muffler delete. That will kill the low end altogether. I drove my car without mufflers and it had no low end pull whatsoever, furthermore the drone was unbearable anyway.

I definitely won't as I want drone free and mild which from reading forums, seems to be what replacing the centre resonator with an x-pipe achieves.
Has anyone tried a merge pipe/kiss pipe arrangement instead of a full x-pipe? I note that this is what supersprint use son their unresonated mid pipes for the 550.

Very interesting. I too have felt very slight gains from using the X pipe. And the straight pipes just feel like no gains, but a really loud sound. I just changed my tips on my rear diffusers connected to my mufflers and the "chug" noise is also less now. So overall I really like how the car sounds with just straight pipes since its closer to what an aftermarket/AMG exhaust would be like. I would like to try how an H pipe sounds though and it might get rid of the "chug" noise completely.

Hmmm, I only did the resonator delete, and I posted vids in this thread.
