Lol The beast was awakened after that and I’ve been super happy since. (Definitely not recommended if you like your neighbors Lol 🏎💥💨&#128520
I dig it bro! The resonator delete was more than enough for me lol, just enough sound without it becoming hella crazy!

Edit: checked out the video, Jesus, it sounds good! Also noticed you're a fellow Singh lol, glad to see a fellow Punjabi in the Mercedes modifying world!

All I gotta say is I heard the tuners recently cracked the ecu and can tune via obd2 now instead of shipping out your ecu.

Just pick one and let the butt dyno decide, then never look back.

Also exhaust..yes must do, very good. I am on catted downpipe, x pipe, e63 mufflers, it is fantastic.

I definitely want the catless downpipes, mid pipe, x pipe and C63 mufflers. I hate all my neighbors lol I called a shop in Washington state where I live and they recommend I get all my performance upgrades (bigger inter cooler, inter cooler pump, BOV, highflow intakes, downpipe, midpipe, x pipe and C63 mufflers) before I get the tune. Also might run 20’s but I really like how the 18’s make my brakes look huge!! Lol at first I thought I messed up by not getting an AMG. Although I respect the brand, I like being different and a bit of an underdog 💪🏽

You’ll want to consider removing the two mini resonators in the middle as well as the mufflers.

Not cutting mufflers off. Sounds horrible. I'm way past this now, this was years ago. I just embraced being a stealth fighter. Cops don't look twice when my average looking silent sedan takes off on a 4.5 second 0-60. I've actually gunned off a couple lights not realizing I had cops right near me. I also love to blast fools that cut the mufflers off their wannabe fast cars, like the Q60 I dusted the other day. I know they're just sitting there like WTF!

hahaha interesting what a year does, right?
I may take a page out and put the mufflers back on once I decide on a tuner, stealth fighter/cop dodger ftw.

I'm on an Eurocharged Tune have 3" MBH Catless downpipes, a 3" x-pipe, and then it is dumped under the car...it's too damn loud, but it does sound fantastic at WOT(before I added the x-pipe...OMG, it was unbearable). I just recieved my 3" 304 stainless pipes and bends, so I'll be finishing that out and adding a couple small glasspack mufflers as well, I've got a few other little things done as well, hoping to run a high 11 next time the track is open...

Do not do the burble mod.....ita awful. I had it for one day on my weistec tune and even at 1000 rpm it would throw out obnoxious sounds

You may want to reconsider cutting them off as I had a full custom exhaust built straight pipe and it sounds beautiful

not too mention the turbo whistle that comes out of the free flowing pipes....youd be a fool not to want that.
