Should i put H-pipe/Straight pipe after LTH
I recently got nagahori racings Long tube headers installed in my 2012 c63 which made my car completely catless(deleting the secondary cats *** well). Although it sounds amazing i was just wondering should i remove the second resonator and put an h-pipe or a straight pipe as i like my car obnoxiously loud. Need to know if there will be any drone. I will not remove the stock mufflers as they are the best sounding ones.

Here’s my opinion after owning mine from new and hearing multiple set ups in person over 13 years.
Never touch the resonator or mufflers, it changes the tone and you lose the 63 amg sound. Also don’t add in any X or H pipes as you will lose it too. The stock resonator has an H so leave it.
Only these options below keep it.
- Stock exhaust with secondary cat delete using straight pipes
- Headers (cat or catless) with secondary cats
- Headers (cat or catless) with secondary cat delete using straight pipes
Also bear in mind some headers change the tone too due to the pipe material thickness and routing. The best headers I have heard are MBH (I own these) & ARH.

And going catless you may have emission issues if you have to go through periodic testing
