H pipe or X pipe?

[matth3wthao]

Has anyone done an H pipe on their 650? If so please share your experience. I'm debating between an H and an X pipe. I understand the difference in sound and performance but want to know if anyone actually has an H pipe. I heard a cls550 with an H pipe and fell in love.

I am curious as well. I installed some M6 Comp mufflers on my GC along with an Exhaustmeister so I can get more of a deeper tone but now I want a little more.

Was curious if an X-pipe or H-pipe or even straight pipes would make a difference and if there are any downsides.

I used magnaflow xpipe on my m6 muffler swap

Update:

I went to the exhaust shop and installed an M6 comp muffler. I took a look under the car and found out I actually have an H pipe. I'm not sure if it is stock or not.

Do we have two sets of resonators? One near the cats and one towards the mufflers?

and lastly, did you remove the resonators and replace with x-pipe? Where does it get installed? I don't want to mess things up under there.
