Maybe a dumb question...but will adding long tube headers to my '11 GS void ANY warranties at all? I got extended coverage so i hate to cancel that out! LOL Thanks for the help guys! Pictures coming soon! Stay tuned!

I am pretty sure that headers will void the warranty on pretty much anything involving the engine and transmission.

Other than catback and cold air intake your warranty will be voided if you do other go fast mods

ITSGRAND

I'll have to disagree. The entire fate of your warranty is up to your local service manager. If it comes to a MAJOR repair, it will often be up to the regional service manager.

I've seen service work denied for a CAI (too much oil on a gauze filter causing MAF problems), and I've had warranty work completed with a supercharger, cam, and headers on a GTO.

Long Tube Headers do not void your warranty in most cases, that is what my service manager told me. Almost anything related to air intake or exhaust is ok.... but LTH's are worthless without a tune... which will void a lot of your warranty.

In addition keep in mind that long tube headers require relocating the cats which is an EPA violation. (Federal, all states)

Yeah, but the EPA doesn't conduct examinations.

Yeah, but the EPA will come down hard on any repair shop that works on a car that has had tampering of the emissions, and does not report it to them (the EPA).

2vettes

Hard to prove. And, you're saying all repair shops have some kind of mandate to spy on everyone?

OP, best to hold off until your 2011 Vette is at least a year (or two) old. If by some chance you get a lemon, no sense giving Government Motors any easy outs to deny warranty work....

My local dealership agressively denies warranty repairs for anything even remotely connected to a performance enhancing modification (including long tube headers and cold air intakes). I wish it were otherwise but I understand why they have to do it.

True but many states conduct annual emissions tests and/or other vehicle inspections to enforce environmental regulations.

Thanks for all the info guys! I'm just gonna stay stock.

in most cases longtubes will void your warranty...and in the republic of kalifornication they are outright illegal on street cars

Wise. If you can't manage with 436HP (with NPP) in a 3200# 2-seater with zero wind resistance and your butt hair touching the street, move into a Z06. Personally, I like the removable roof and F55.

ITSGRAND said it best. Depends on the dealer. Headers should not void the warranty, but some dealers may try to tell you it does. You almost certainly will have a CEL which they will complain about. Then you get a tune to get the most benefit from the changes and you just voided your powertrain warranty. Enjoy your new car!

my dealer straight up told me that headers will not void my warranty

I luv threads like this....

To maximize your gains with headers or even a CAI, a tune is necessary, and that will void your powertrain warranty
