Performance mods that don't void warranty

Are there any mods to increase performance besides an ecu tune ? I want to do headers but I would have to cut my cats . I thought about a remote turbo but there are none for our cars do it would still require further mods voiding warranty .

You can usually get a dealer to do warranty work with an exhaust, but without removing the cats you really don't get anywhere. On a C350, the best bet is an ECU tune - we can take you to a 300 hp file that is undetectable, and - if you're still nervous about the tune and warranty - can provide you with a Block Tuner to set it back to "factory" in minutes.

I already have a tune by Powerchip , are saying that you can buy into a warranty program with Metcedes that would allow you to do aftermarket work to your exhaust ? I'm a lease but I plan on my buying my car at the end of the lease term .

No, not saying that at all. Mercedes does not "cover" ANY aftermarket modifications on their vehicles (regardless of a certain tuner's crack-aganda to the contrary, there is NO TUNING covered by Mercedes' factory warranty, which you can view in detail here (attached file).

What I am saying is that dealers have an incentive to work on your car under warranty. Warranty work usually pays better than client work, and the dealership knows you will authorize the work (if it's free to you) and they will get paid by MB. If you have a good relationship with your dealer, they can try to submit your repairs for a warranty claim. If you have an aftermarket exhaust or whatever, they might look the other way. It's up to them what they submit, and up to MB to approve or deny the repair.

In other words any work done to my in terms of modification I get the shaft . Let's assume I installed the headers , would the warranty only be voided on the headers or on the entire exhaust system ?

That's up to Mercedes-Benz, and they would have to be made aware that the headers were on your car by the dealer. If you have a good relationship with the dealer, as I said above, they will probably submit the claim.

That said, Mercedes can void the warranty for pretty much whatever they want. From the attached document:

DAMAGE DUE TO ACCIDENTS, MISUSE OR NEGLIGENCE: Accidents or damage from objects striking the vehicle. Misuse of the vehicle such as driving over curbs, over- loading, improper operation, storage or transport (Proper use is described in the Operator’s Manual).

DAMAGE DUE TO ALTERATIONS: Alterations by changing or adding to the vehicle can adversely affect its performance, relia- bility and longevity and are not covered by this warranty.

It's up to them.

About 30 peak HP, 10 TQ, as on our website. http://speedriven.com/products_parts.html

That doesn't show the gains across the rpm band or improved throttle-response from the ECU tune.

Entire system...MB will crucify you for any mods and will make every effort to lay blame for any problems to your mods EVEN if they have no definitive proof. I'm talking from experience.

I've seen cars with full exhausts and intercooler upgrades go through warranty claims with no issue and otherwise stock cars with tuner wheels and badges get a status 8 just because of the tuner badge, with very little in the way of predictability ... except for this: it seems to come down to the client's relationship with the dealership. Be good to them, treat them like humans doing a job, and don't blame them for trying to keep their job, and they just might try to help.

I treated them great. It wasn't their call because it was bumped up to their regional rep. It was only my good relationship with the MB SA that I got the car back without MB dealership charging me the cost of investigating the problem.

The dealership was literally holding the 55 hostage if I didn't pay them the diagnostic fee of $1100 (all labor)...they did a tear down of the engine. The SA called me on his cell phone and told me that I needed to write the dealership and tell them that I did not authorize (no signature from me) the tear down and that before they did that they should have gotten my permission. He told this to me on the down low behind the service manager's back.

To this day they MB has not definitively told me the cause of the engine damage. I got the car back and had the block rebuilt for just under $10k vs MB offering me a "deal" on a used block for $17000 NOT installed.

To the OP, I agree with Speedriven about keeping a good relationship with your SA. They may look away or give you a pass on certain things BUT I am guessing if the warranty repair exceeds certain parameters (I.e. Cost) it is out of their hands.

At the end of the day, your SA is all you have. It doesn't always work, especially in Florida (where the regional guys are AGGRESSIVELY anti-tuning), but it's better than nothing.

Agreed. I have been lucky getting SA's that were really cool guys and actual gearheads.

Same here.

It's all subjective and depends on your SA.

Technically, they dealership should no void any part of your warranty unless they can prove the aftermarket item caused the part in question to fail. However, what they say generally goes, unless you fight them. In the end, it's not worth the hassle. See what their stand on mods is and go from there.

This will probably be your best option to get some extra ooomph. The less the dealership can visually see the better plus being able to maintain a stock ECU file is so very handy.
