Default Header Install Voiding Warranty & question

Howdy! I was thinking of getting pacesetters (long tube headers) and a different ORY to go with a Magnaflow catback as all i have now is a MTI lid.

1.) But I was curious as to whether or not this will void my warranty as i have a GM extended warranty to 100k miles?
2.) Will this install be way too loud for daily driving in your opinion?
3.) Would there be any computer mods (or deleting anything) i would need to do due to the much more free flowing exhaust?
4.) Would I see 375 RWHP on this setup?
5.) Would the Catalytic Converter still easily be able to be in place?

Thank you for your time and baring with my ignorance. I read the stickies but want to get what people's opinions and answers are...thank you!

1) It likely will void your warranty, but some dealers are a lot pickier than others.
2) In my opinion no, but that's my opinion.
3) It might run a bit rich but you don't NEED any tuning, the computer does adjust itself to a point.
4) No. You won't.
5) You said you were going to get an ORY, that eliminates the cats. You would need a catted Y, not an ORY if you wanted to keep your convertors.

Installing headers does NOT void the warranty outright. It voids the exhaust system portion, but when you put long tubes and an OR "Y" pipe with an aftermarket catback on there you pretty much already said to hell with the factory exhaust system anyway. Once you get that system on there I'd be willing to bet there is little to no chance you'd want to go back to stock even if GM would pay for it. That's why you have the warranty, right? To have GM pay to put it back to stock which you don't want anyway. I think you answered your own question.

Computer tuning would be a great idea, and easy to get considering you're in the Houston area. If you don't want to pay for a full out dyno tune, you can get the codes deleted for cheap, usually less than you'd pay for O2 sims. MTI did mine for $75.

You wouldn't see 375rwhp with every bolt on in the arsenal, but a cam could get you there EASY. 400rwhp isn't hard to get either, especially with a 6-speed.

Any exhaust that runs out the back will not be too loud IMO. You'll get so used to just about any exhaust setup, that it'll sound like stock to you.

Long tubes and no cats would void more tha just your exhaust portion of your warranty. A dealer will come up with all kinds of reasons not to touch your car. For example, they could say long tubes increase under hood temps and thats why such and such part failed. And, its illegal to remove and or move your cats from the factory position. So who are you going to complain to because they will just point that fact out. And, there's not a chance GM would pay to put your car back to stock.

True. The biggest dealer response to headers is that they change the engineered internal flow rates. If you have an ORY you can forget about most if not all dealers working on your car too. They won't touch it with a 10 ft. wrench.

Hopefully you won't need warranty service anyway, but if you do it helps to know somebody in the service bay and some of the mechanics. This makes a BIG difference. It's the mechanic who would tell the service tech you have headers to give him an excuse to deny your service claim. They can't claim that just because you have headers they won't honor service work on your ABS system for example. If they do you have to stand up for your rights and get on the phone to GM headquarters and rat them out. At my local dealership most of the mechanics drive Camaros and Silverados which are highly modified and spend quite a bit of time at No Problem Raceway. They don't rat out customers to the service tech when a vehicle comes in with headers. They won't service your exhaust system, but they WILL work on everything else.

put that money towards 4.10's and a ram air system (FTRA, SSRA). you'll see the same, if not more, 1/4 mile gains and GM will have no idea you changed anything as everything will look exactly the same i believe. headers are noticable. i don't see how a gear swap can void anything?

I had my entire T 56 rebuilt about 5 years ago under warranty with Mac headers and an ORY. They didn't care at all.

As to whether the daelership is going to care about headers, it depends on the dealership, some will try and void your warrenty for a K&N filter, others don't care if you have heads, cam and a blower, it also depends on what system you're talking about, if you have headers and need a warrenty repair on the window motors or the ABS brakes, it's going to be one hell of a stretch to try and show the headers caused a window motor to go out, or an ABS module to fail
IMO forget the extended warrenty, cancel it (if possible) and save the money

On the warranty voiding part...

As much as it shouldn't void any more than just the exhaust, dealerships are notorious for coming up with every excuse known to man in terms of having reasons to void them. It's ridiculous, but they do.

"Your headers raised the temperatures under the hood and made the car more powerful, which, in combination, resulted in more pressure as the car went faster and boiled your blinker fluid, therefore adding heat to the headlight and resulting in your failed window motor. So we've decided to void your warranty."

Any catted Y that positions the location of the cats in any position other that in the stock configuration is an ORY.

What?

No.

Catted Y = Any Y-pipe with catalytic converters
ORY (offroad Y) = Any Y-pipe without cats.

i think he means it's illegal for street use since it moves the cats, making it for off road use only since it's technically NOT street legal. we consider ORY's to be y pipes with no cats, but technically, in places like CA where it's illegal to move cats, a catted-y is an ORY. that's what he means. he's right from a technical standpoint, just not an LS1tech jargon standpoint
