2014 cls 63AMG S

New G63 AMG S

Hello everyone

i am currently waiting for my G wagon to be built. I have been looking around at aftermarket equipment. Does anyone have a strong opinion on aftermarket exhaust ? Down pipes. What gives the most power ? Best sound ? How about aftermarket intake system?

how about turbo upgrade ? Intercooler ?

brabus is asking 50k for the 800 HP package

wiestec Is around 10 k for around the same power but I don’t believe it comes with an exhaust? Is that right

renntech looks to only be tuning ?

am I missing any other options ?

Thanks everyone !

A member here put the Akra exhaust on his and it sounds real good. And a Renntech tune is used by some others - they have been around for years so probably a good bet.

Otherwise, are thinking about cosmetic items?

At nearly 600hp on tap from the factory, the only thing you’ll accomplish by modding is incinerate cash and maybe add some bragging rights, while also voiding your powertrain warranty. There is zero need for more power in this car.

Frankly - the RennTech HHT (Hand Held Tuner) is the Least Effort for Maximum Gain... and in the event you have a dumb sh*t MB dealer form Service - to prevent a irreversible VMI Flag from some hack MB Dealer Tech - you can "reverse tune" back to OE spec in 2 minutes before you pull into the Service Drive... it's righteous - no CEL's .....

2014 cls 63AMG S

I understand what your getting at..
however my daily driver is a CLS 63 Amg S 2014 with down pipes, full length exhaust and an intake . I feel with all that weight the g63 will feel sluggish comparatively. I just had a kid so I need the room for the car seat, the cls is not practical with a car seat in.

The G63 is surprisingly quick and if driven hard with manual shifts can perform fairly spectacularly; and it handles well on the road. Suggest you get through the break-in period and push it quite a bit to see how it performs to your expectations. I'd be curious if these enhancements make a real difference in day to day driving experience but if you end up going down that road I eagerly await to hear your feedback/results!

no way, so your saying with a rear facing car seat there is little room in the passenger seat? Would an ML or GLC have more room ? My brother has a ML 63 and it looked pretty decent. I didn’t think the g wagon would be less

These Gs are not sports cars, and in fact the car is severely overpowered from the factory, for what it is. The fact that you haven't driven one and don't even know if your car seat will fit, yet your first post is an inquiry on how to mod it for more power is a bit comical, to be honest.

By the way, MB can easily tell if a car was tuned, regardless of whether you flash it back to stock before you take it in to the dealer. There is logged data stored in the DME that can be accessed to verify historical boost levels, etc. Best of luck to you either way! You're getting a great car!

It's comments like this that kindof take me sideways......"By the way, MB can easily tell if a car was tuned, regardless of whether you flash it back to stock before you take it in to the dealer. There is logged data stored in the DME that can be accessed to verify historical boost levels, etc."

Technically, the statement is is correct - but that's not even close to the point.... it's assh*le owners with "modded" Mercedes - that after they get their Dealer Service Dept all worked up - especially with Modded Tunes that have set off CEL lights - that get "surprised" when either (a) that Dealer reverses the Tune to factory spec or (b) that dealer flags their VIN # where ANY future Warranty Claim MUST be reviewed by MBUSA for approval, and that VIN flag cannot be reversed.

MBUSA and RennTech have absolutely no "conflict" whatsoever - Mercedes Dealer's are even allowed to become RennTech dealers if they choose.

The RennTech HHT is the "bomb" when it comes to performance upgrade - no labor - no replacement of mechanical parts - and even has the the "convenience" of switching your own tuning back to MB-OE before you check in with service.

The only NaySayer's - are those owner's who prefer to shop "budget" $1,000 tunes - and frankly on a G550 or G63 there is nothing here in the US that comes closes to the reliability and performance benefit of the RennTech HHT

The take away was let’s not kid ourselves or give out false info. If a warranty claim involving the power train on a nearly new G63 were to arise, there is a good chance data logs which get extracted from the car would be reviewed by MB engineering, at which point they would easily and quickly discover the DME has been tampered with. The dealer has limited say in whatever happens once the car is flagged in the MB database. It’s not the dealer’s fault when one decides to throw aftermarket parts on their car - nothing wrong with that as long as you don’t expect the manufacturer to fix it when it breaks. Pay to play.

To suggest that someone could get one over MB in 2020, with all the tech and diagnostic capabilities packed into these cars is a bit of a stretch.

Now having my 2020 G63 for 3 weeks, granted only have driven 300miles so far, I can tell you these cars are overpowered... engine is way too big for the car... and this is coming from someone that owns supercars. The car is insanely fast and the sound when intake is open may even have more growl than my 720s! Touching this car with a tune or exhaust is travesty IMHO... Its too good and given the shape (i.e. lack of aero, too top heavy), you will never reach its full potential. Note - i was going to Renntech tune my prior incoming G550 which i pulled out of and got G63.... IMHO, you should not touch the G63... it will ruin its character and likely void a warranty...

What will give you the most power from an exhaust standpoint are downpipes. Best sound would arguably be the muffler. Aftermarket intake is a solid add-on for the relatively low cost.

Turbo Upgrade + Intercooler is obviously a huge upgrade that will completely change the performance of the car. It'll be similar to what a Black Series car is to it's relatives in regards to the performance numbers.

Brands like Weistec & Renntech will add more and more performance parts for the SUV as time progresses. If you're unsure about each's offerings or would like to know what may be in the pipeline feel free to reach me directly - David@WheelsBoutique.com || 786 249 0127 ext. 2109

I"m putting an IPE exhaust muffler on mine. I didn't go with the whole system because you have to cut the pipes on the 2019+ and attach together. If you do that you will also need a tune. My car arrives next week, so I have everything lined up.

Do you plan to lower the G or put after market wheels?

Nice let me know how it sounds. From what I’m gathering, to do the full system you have to go custom?

I don’t plan on lowering or changing the wheels initially . I got the factory forged 22 inch in black. I will probably get a set of aftermarket like I have with my CLS (OZs)

What is considered a full exhaust. IPE, Akropovic, you can get the full exhaust, but need a tune after.

IPE sounds great and it has the 3 exhaust pipes on each side which look mean.

What you need..

I’m having an Akrapovic Titanium Evolution Exhaust with front link pipes fitted in the next 10days. I’m ether going with a RennTech or DMS tune (DMS are a UK specialist). I’m undecided which company at the moment but have heard very good things about RennTech.

Ether system will produce close to 750BHP and they sent me this video when I asked what would the sound be like. Enjoy 😊

What would be considered a full system on these G-Wagon's are Downpipe + Muffler.
