I recently purchased a 21 gle53.. always had older muscle cars, I’m fairly new to the European game. Looking to get around 550-600 hp out of the gle53.. what is the best way to do this? Also so, what’s the best exhaust system in your guys opinion?

Buy a BMW X5 M50i or M60i now. It shares the same engine as the full blown M. Cheaper than the 53 blazing fast. Nearly as fast as the GLE63s.

I’m not sure you’re correct on the “same” engine unless any twin turbo 4.4L is the qualifier. The M50i is only 523hp vs X5M is 600hp and what I have the X5M Competition is 617hp. Also the numbers just don’t compare on “almost as fast” with the M50i or slightly slower M60i (reference ThrottleHouse reviews of both) and not close to the same as the AMG GLE 63S. I have both the AMG and the X5MC and have a pretty good frame of reference. Personally I love both for different reasons. The X5MC is more athletic however more harsh in every way compared to the AMG 63S. The AMG is more luxurious and larger feeling inside with both being full maxed out with every option. The AMG blows away the X5MC in exhaust note and truly bad *** looks and can beat the X5MC on everything but launch control since the AMG version is not nearly as good. The transmission of the BMW is sublime while the AMG likes to hunt and take a smidge too long to find the right gear. When manual shifting it’s a whole different story for the AMG. Just my $.02 having the privilege to own both of the most recent versions.

Advice for the OP, buy a 63S if you want the most HP and sickest sound with the most luxury and always drive it in Sport. To make the BMW sound nearly as good it takes $12k of Akro easily making the two cost competitive with the right options.

He's talking about the new 2024 refresh. The M60i** specifically will indeed have the "same" S68 engine as the proper M. It'll be at least detuned, dunno if there will be any physical differences (like smaller turbos) or differences in supporting parts (oil cooler, intercooler, etc).

I also agree, buying the 63S would have been the better move. Sell the 53 and then buy a 63 instead if thats financially possible.
Otherwise you're looking at tunes and upgrade packages from places like Eurocharged, Renntech, Brabus, and I'm probably missing a few others.

Also FYI upgrades/parts/tunes for these cars will probably be more expensive than what you're used to with muscle cars. Unless you're talking about collector-level vintage original parts..

Understood since he mentioned both the X5 M50i (now) and M60i (2024) however the HP is still the same for the M60i and has the 48v mild hybrid.

Going with the 63S is the better way to go IMHO. Adding some upgrades to make it insane HP is an option like with the X5MC but neither really need it. Add the Racechip to the BMW and get a nice boost if that's you're thing (OP)...

Review of new X7 M60i which talks to engine etc. and will be identical to the X5m version minus some weight and third row.

Yeah. Using the same engine is great for M lite buyers but it kind of takes the luster off of the full blown M in my opinion. Usually there are physical differences between similar engines. Like the SQ8 and RSQ8 engine, for example. Or the older 4.4 L found in the M50i vs the 4.4 L in the M. Everything is very similar but there are distinct differences like the turbos were usually different, cooling, etc.

That isn’t the case here; it’s just an engine tune by all accounts. Which means you can buy the X5 M60i and easily tune it to the M level without any real risk. In fact I bet it won’t be long where you can literally buy a perfectly matched M tune.

I'm not a fan of new engines and/or a major addition of new parts on them like in the BMW until they are proven. The M177 LS2 engine which is in the E63 and GLE 63 is one of the best AMG engines ever built to this point and has a rock solid proven track record of almost seven years now.

Frenetic

Well the point being is that he can literally buy an X5 M60i for probably less than an overpriced AMG 53, spend a couple grand on a tune and have over 600+HP (which is probably $30 to $40k less than a 63s with the same or more HP). Or, just buy the M60i with 523 HP for again less than the 53 and do 0-60 in the 3 second range. Something no tune on the AMG 53 can probably safely achieve.

Simply put: he made a mistake buying this car if he wanted to go fast. I knew that getting it as I didn’t care anymore but this thing is a POS for other quality control reasons.

I'd rather buy a car that has the power to satisfy me out of the gate. Most people aren't willing to buy a new BMW or GLE and tune it for obvious reasons/headaches. Some - yes, but very few.

PandaSPUR

If you're just looking for HP numbers for bragging rights, you're probably right that a tune is all you need.

But I would bet that the proper M has more cooling capacity to handle the higher power its tuned to. That part will be obvious once we see the proper M cars debut in a couple of weeks based on the vent openings in the front bumper.
Then theres also brakes, suspension, chassis stiffening, etc. Many things can be different between the M60i and proper M that we won't know about until the proper M is released.

I agree with the rest of what you said though. The 53 and 63 are definitely overpriced once you factor in dealer markups (that are still persisting in my area at least).

benzbell

I ordered my GLE 63 on 4/14/2022 and got it 7/25/2022 which is lightning fast and with no constraints on any options I ordered and paid a 12k dealer markup. To me that was reasonable at the time considering I got exactly what I wanted and how fast I got it. GLE 63 is a very good value proposition for what you get and in my opinion is definitely in line with other competitors. Have 7k miles on it with no issues whatsoever. Absolutely love this car and yes I did check out the competition (X6M, RSQ8, Porsche Cayenne Turbo) as well. In the end I preferred the GLE .

Yikes! That thing is ugly, and the back half already looks outdated like a '08 GL450

It was that exact desire to get more that lead me to upgrade from my 2021 GLE450 (which I loved) but kept trying to find ways to see if I could increase performance to a pre owned 2021 GLE63s with 6,000 miles which honestly has been nothing short of incredible. I have not driven a GLE53 so I can't give a comparison, but I can tell you that the 63 doesn't have me wanting for more so far and for whatever complaints people have on this model, I think it's brilliant. That engine has the most satisfying pulsing V8 sound while driving. When I looked at any of the tuning packages and or mods, I kept reminding myself that it's money lost when I resell or trade and for the input in of funds, the returns just don't add up and mods are a rabbit hole of expenses and risks of adverse wear on the engine or car are there.

Hello All.
I have a beautiful 2017 BLK/BLK GLE63 and have done an exhaust upgrade. I feel as though "HE" has so much more to give and was wondering if anyone knew of some inexpensive mods to get more power out of it. I have to believe the only diff between the GLE63 and the GLE63S is probably turbo boost but ????

Love to hear your thoughts.

Thanks,
Pete
