Used M4 Questions

I just bought a 2016 M4 Convertible from a dealer. I have two questions I'm hoping the group can help me with. It has an aftermarket exhaust with blue titanium tips. It's super loud. I'm not sure how to identify what it is or whether or not it's offering anything other and acoustic/aesthetic compliments vs performance. Also, when I start the car, the instrument cluster displays GTS before disappearing. Obviously it's not a GTS. Is this standard? Does this mean the car has been tuned? Any easy way to find out? The car drives like a dream, so this is in no way a complaint. I'm just really curious about every little detail. I've included a couple of pictures although I'm not sure they help much. Any thoughts would be appreciated!

First of all, Congratulations!

As for the exhaust, unless you put it on the Dyno. and get under there and see if there's any branding,
there's no way to tell. The tips alone, could have easily been replaced. If they're turning blue, they
could be Ti. There's a Japanese exhaust ("IPC" - ?) that offers this.

The cluster showing, "GTS" is indicative of it having been coded to show this, not necessarily tuned.

You can have a dealership plug it in to "ISTA" and they can easily tell you if it has been (flash) tuned.


Cheers!

"2016" - Used... Original Warranty not tranferrable.

OP should know what warranty coverage he got from the "dealer" where he bought it.

It's his post/his query. I just provided a route to resolution. What did you provide?!?

That dealership sold him the car in its' current condition, so there really should be no
problem with him wanting to inquire about the cars' history albeit, this should have
been done prior to purchase.

so the 4/50 BMW warranty isnt transferrable?

I pointed out you are talking out of your _ _ _ _. Sometimes that can be even more valuable that fanboi nonsense.

A 'dealer' is not BMWNA/AG. If the dealer sold it with mods that void the BMWNA warranty, there is ZERO assurance that the dealer will help. Indeed I was involved with a car that was sold as a CPO with a DME flash on it. Problems happened, mfg refused saying 'car was modded, warranty is void' Selling (and CPOing) Dealer's response? "You should have inspected the car"

The point, never mention the CPO car has mod after you sign the dotted line

I can see the servicing dealer refuse the warranty work, cause as far as that dealer goes, how do they know the mod was put it by original owner or current owner. MOD always means Warranty voided

Just to put a point on it..in the case I was mentioning the selling dealer CPO'd the car, with a flash on it, and when the engine failed, that same dealer handled the failure- the mfg refused to help and neither did the dealer.
