If I remove the center muffler and install a cross-pipe or x-pipe, will my Porsche warranty be affected?

 

In all common sense, it should not, and, to be honest, this is a mod that can be reversed in 15 minutes and would not be detected...
It would be the dealer's (and PNA) call, as usual, but I never felt pushback on exhaust. I have even seen a car CPO'ed with a Borla exhaust at the local BMW dealership yesterday.

 

Anyone on here ever have a dealer have a problem with an aftermarket exhaust?

My car does not have PSE, and since it is a 3.4 it is not wired for the valves either. So installing the PSE now is a bit of a PITA.

 

Most dealers won't have a problem with it... mine does all my modifications for me. I'd leave the ECU alone, but anything exhaust related won't matter much. Just call your dealership.

As long as the cats are in place you should be fine.

 

They probably won't void your warranty and won't give you any problems... providing that an issue does not arise that can be linked to the exhaust system.

I posted this earlier in another thread; it may help you.

It will vary from place to place, and it depends on the situation. Like you said, some dealers will close their eyes and pretend that some modifications simply aren't there.

Just to clear something up for potential customers and other readers, though: I think the term "voiding your warranty" is being loosely thrown around and somewhat misunderstood. Most dealerships will not outright "void" your entire warranty when they see a modification on your Porsche. What often happens is that Porsche may *link* a problem on your car to the modification and deny any warranty coverage. For example, they may deny coverage on an engine failure if their computers show that you have a tune installed and really, really pushed the engine to its limit. They can't, however, deny you a claim for a faulty rear taillight if you have a GIAC tune installed.

Yes, some dealers may outright try to "void" the entire warranty, but that is illegal under the Magnusson-Moss Warranty Act. Problems arise when a dealership actually puts a foot down and denies a warranty claim for an illegal reason; at that point, you can either sue them under this Act and fight them in court, or give up and pay for it yourself. There are numerous threads regarding this Act if you do a quick search.

The dealer's reaction and their subsequent actions are really crapshoots. I've had nothing but pleasant outcomes in the past with my modded Mustang GT and warranty replacements through Ford (transmission, engine components, etc.).
