Do headers.......

void the manufactory warranty? Also, I was told that I could have a BORLA exhaust kit that can be installed with out it affecting the warranty. Is Borla my only option?

Catback's won't void your warranty...as far as headers go....99% of them will cause your car to throw a CEL code....and the only way to get rid of the code is with a tune. Most dealers will void your warranty if you decide to do a custom tune. Plus, you would probably want a tune to realize the true benefits of headers. My advice, and it's just that, advise....if you are worried about your warranty...stick with catback systems and do headers after your warranty expires.

Good advice. Thank you very much.

99% is a bit strong. Most main stream SLP/Kooks etc will not throw codes - I have kooks headers, high flow cats and Mach XL Catbacks, no codes yet and no tune. As for your choice --- its huge, JBA, Corsa, Kooks, SLP, Stainless, pacesetters the list goes on....

True - a tune will benefit if you fit LT headers. But I have found this combination sounds fantastic, and adds HP without a tune (SLP say 25hp advantage without a tune)

Shorty headers - do a search and you'll find that they do not add much if anything in HP gains

If i had any warranty concerns i could simply re-fit stock headers and take it in. 5500 miles and no complaints

Stick to Catbacks if you want to retain warranty

As for tunes and warranty Don't go there!!!

shortys will void warranty, not at first.. but over a period of time.. if you have a cat back and CAI and shortys .. thats to much extra air flow... the car wouldn't know how to handle it.... then will you have problems, the dealer ship will say your aftermarkets parts caused this, which is true... you might blow a piston or something

One thing you need to consider about adding headers is that you are significantly increasing the air flow of the engine. One of the more important things the tune is going to do is make sure your Air/Fuel ratio is good. By adding headers you are going lean out your fuel mixture. I believe that the factory tune on the Camaro is supposed to be pretty rich but if your headers happen to lean out your A/F ratio to much you'll take a big chance on burning a piston.

So...lets say that I put on headers without a tune. The car runs fine for a while and then all of a sudden you eat a piston. You take it to the dealer to look at and even though you have the factory tune they will surely determine that your headers are what leaned out the car and caused the issue. Then you'll be out of pocket to fix everything and possibley loose the drivetrain warranty anyway.

So....technically just adding the headers could cause you to have your drivetrain warranty voided with or without a tune.

All of that is above and beyond the fact that your car will run much better with the tune....again becasue they are getting your A/F ratios and things like that to run optimal for your car.

Talk with some of the tuners/performance shops and see if they don't agree.

For me....I'm waiting to add LT headers until I'm ready to do a tune and take that possible chance that either the headers or the tune might void my drivetrain warranty.

If you don't want to take the chance on voiding the drivetrain warranty then you probably shouldn't put the headers on.

Just my take.....

How bout 99.9%. pretty much bank on a CEL light...

As for all the burning up pistons talk... there are plenty of folks w/ headers and no tune who are not trashing their engines. The car will learn the new airflow and make adjustments. You will have nice HP gains and the car will sound like a beast.

It is recommended to get a tune with headers and a handheld tuning unit will do this nicely... then you can restore the stock tune when needed...

Those are good points mlee...there has been some disagreement on the ability of a dealership being able to sniff out tunes when they have been restored to stock programs by handhelds. I have no experience in this area so I'm just bringing this up for conversation and not for the sake of argument. Either way, your best bet is to find a mod friendly dealer. Sadly, we don't have any here in Albuquerque.

The main problem with your "take" is that shorty's don't significantly increase the airflow through the engine. It's debateable whether they flow more than the stock ones at all. For the sake of arguement, lets say they do. They haven't been proven to gain anywhere near the 18hp that most companies claim. I highly doubt you're going to burn up a piston with a 5-10hp gain. The PCM can EASILY compensate for that little of a change.

...and in addition to the topic, one thing shorties will provide every time is weight reduction.

The real performance gain comes from removing the stock cats. Shorties are not worthless if you replace the stock downpipes, with or without high flow cats. At that point you may as just go with LT's and get that extra 10HP however. In the end a tune will be required.

Winner Winner Chicken Dinner.

Stock cats are the bottleneck in the system. The manifolds in stock form kick ass.

Shorties are awesome for looks and ultimately performance if you dump those rediculous cans off em.

Believe that.
