2012 E350 resonator delete + x pipe sec cat + C63 muffler
I have deleted the resonator and replaced with straight pipes, and few month later also replaced the two small cats with a Xpipe. The result was under my expectation, it quite down the sound after doing the Xpipe, and no more rumbles. I found the exhaust flow is not smooth around 1k-2k rpm, especially going uphill. Anyone knows what I can do to refine the smoothness and better sound without losing too much low end torque?
coz the reason why I wanted a xpipe was because I lost quite a bit low end torque while I delete the large resonator. I also heard that NA cars have bigger lag once you lose some low end turque compare to Turbos. Is that true?
I also thought about gutting or deleting the muffler, but afraid of drones and losing more low end torques. Would a Hpipe helps? I have been reading forum all round mbworld, and seen some people did a hpipe over xpipe.
Anyone suggestions will be appreciated!

i wouldnt advice deleting your mufflers after the xpipe, it would sound like a lawnmower. c63 is one of the best sounding AMG mufflers to date. you might wanna go with that if youre lucky to find one.
