Honestly I've found next to zero info regarding these S68's and their capabilities or lack thereof... I'm likely going to go with whatever tuner that can offer me two things... 1. Remote flashing and dyno tuning 2. The ability for me to flash my car back to stock with my stock file.

I'm a little skeptical with custom tuning in general for the F95/F96, I have yet to find anyone that has had their car tuned yet these tuners are claiming HP and TQ numbers, kinda weird. I know that tuners are buying DMOS files from Europe as they aren't mapping their own .bin files.
True and looking forward to hearing what you ended up doing and how much whp you got, my man!

I had a good conversation with a gentleman at 412 Motorsport in LA who tuned my brother's GLE63s to 900hp, and it's working magnificently for 15 months now, the only issue is exhaust tickets coz it's catless haha

personally planning a visit in 2028 after the warranty runs out and start exploring

Nice, it looks like 412 uses DME Tuning for their stuff.

Being in Northern California we seem to have a lot less density of "fun" cars on the road :D. LAPD and LA County Sheriff's don't play any games. Ha.

I plan on drag racing my car, I'd like to run a 9 second 1/4 mile but we'll see.

Yes, Southern Cali is a bit out of control, any brz or 340 are downpiped and cruising around like mini Uzi, so annoying haha

Very excited to see where your path will take you. I will be waiting for updates! If you will need to contact "their" guy lmk I have it saved ;)

Here's another video
That sounds ridiculously loud. That's just the primaries and secondaries deleted? It sounds like it needs an x pipe and a resonator.

whelp, my skyley chinese downpipes will be here on friday. Car is still getting PPFed but I may have it back by then. I will take a good picture of the underside of the exhaust system on my lift when I get it back.

Its definitely louder than it was... Yep this is just stock exhaust with catless primaries and secondaries. The car set a check engine light, i just bought Bimmerlink and an ENET cable, going to check the codes tomorrow to see exactly what its showing. If it has a code i'll just tune the stupid thing.

Womp womp, I cleared the codes we'll see if they return... Not unexpected.

Also not sure if anyone has swapped out their downpipes before but I ran my car through a few heat cycles and low and behold the hardware all loosened up quite a bit, I re-torqued everything again... just thought I'd share.

What's the best route to clear CEL? I am soon to swap my primaries and a tad bit worried that even 400cell can give me CEL. So, I'm thinking of ways to be extra safe. So far, I've heard that JB4 is good, but it looks like a waste to use it only to clear CELs...

Make sure the washers they give you are nord-lock washers.

I'm going to end up ripping the mini cars out always and tuning it. The car is slow, so slow.

After driving the car for about 10 miles (I drive it about 100 miles a month, maybe.) It really isn't that loud, cold start is obnoxious but it certainly doesn't sound like a straight piped turboed car in anyway. It's nice to hear the turbos a little but I still don't really hear them spool in the cab, you can definitely still hear them out of the exhaust. Definitely a lot more noticeable pops and bangs. The exhaust is much deeper in tone. The car is still setting a check engine light (it came back). Once the car is up to temp the sounds out of the exhaust at idle is very tame.

oh wow! Great miles! I drive around 100 miles a day...

The best feeling when mod is making you excited about an exciting enough car. What's your plan for CEL?

I agree, I really couldn't stand driving the car with the stock exhaust and catless secondaries it pissed me off... Knowing that this where i'll stop with the exhaust (stock exhaust and catless primaries and secondaries) I'm actually happy to drive the car...

I'm going to rip out the mini cats and tune the car... There might be some exciting news for tuning for these cars coming soon :D.

It needs a trans tune too. I'm getting accustomed to my 26 and I don't like it. I miss my 23...


Anyone figure out how to make the damn thing not honk when you walk away while its running with the keys in your pocket?

Also question: Even if you turn ASD off do you still hear the speaker system with it's fake little bass notes upon shifting? I swear it's not the exhaust but the speakers and supposedly ASD is coded off....


I have my downpipes ready to install just waiting for my other mini-cat variants to come in.

The honk is there to stay. One of several things I hate with the LCIs. No comfort rear entry irks me as well as I haul the kiddos everywhere in my soccer dad mobile.
