Don't do straight, yea it's louder but not in a good way. Also being straight the two sides don't mix and balance anymore so the exhaust systems tends to shake the car. I also feel like it hurt the low end torque. Installed a H after driving around two days with straight pipes and am much happier, sounds much better, exhaust stopped shaking and the low end grunt returned.
Going to do H. Before I do it is there any reason this would cause any warranty issues?
Don't worry about warranty on a reso delete , it won't affect the car in any way except sound , I'm looking for a weld in h pipe myself , did you find anything?
I went straight instead of the resonator but it sounded like a truck. The resonator has an internal H so I had the shop add one of the same size in the same place. Sounds great and just the right amount of moderately louder. Don't buy a prefab kit - a decent exhaust shop should be able to whip something simple up for less and you'll still have to pay them for the same labor.

I posted a thread a while back if you want to search for it. As long as you leave the stock mufflers in place you'll be ok. As RJStanford mentioned, straight pipes sound too much like an American truck to me but it was awesome on up/down shifts!

Thanks for posting , everyone says straight pipes are louder but that doesn't mean better , I don't want my car to sound like **** either , I'm glad the h pipe worked out for you.
What size pipe is the exhaust? Magna flow sells a nice X pipe , I wonder how that sounds vs the H pipes

98% sure its 3" back there - if not it was 2-7/8" or similar. My exhaust shop just matched the pipe. The H was pretty small, maybe 1" or at most 1-1/2" diameter. I figure that MB had done their homework as far as that went.
FWIW, I think I ended up paying around $125 all-in for the work and materials. Definitely check with your local shop before buying something online.
I've got the straight pipes done with no cats and still retain the stock mufflers. It does have more "BArk" "Crackle" but seems to also have a unevenness about it that I can feel. I think I'll end up going X pipe just for the smoothness but maybe before that since its Cheap add a 1" cross pipe and see if that works.
Here is what it currently looks like:
