My two cents. Should have nothing to do with warranty or emissions.

Warranty states if a mod causes a problem it's not covered - hard to imagine what they cld claim this mod broke - never know though.

This is the resonator, not the CAT, no effect on emissions.

But that's just my opinion. We've had lots of discussions regarding both topics on here and I will say that is the general consensus. A lot cld depend on the attitude of the dealer or mood of the emissions inspector, always bring them chocolate!

Ah thank you, finally an answer! Greatly appreciated buddy, I think I'll take her to one of the local muffler shops next weekend. As long as no one has had any lights come on due to removing this, that was my main concern. My service manager had said something about back pressure causing the light to come one, but if no one has had that issue I guess I'm in the clear.

With the warranty, I suppose if there was an issue with the exhaust system it would no longer be covered due to the modification, but this is the only "performance' mod I plan to perform anyway, aside from possible a CAI, so I don't think I should have to worry about any issues with my exhaust.

I noticed the exhaust has a slight burble at idle if you listen by the pipe. I can't wait to see hear it without the resonator.

When i took mine in they cut the resonator out and put in a pipe they cut and bent. I thought about keeping my old resonator but decided i would never use it so i left it there.

If you have any concerns takle the resonator with you. That way if you have any problems down the road just pay some one to have it put back on. I cant imagine it costing any more to put it back on then it did to remove it.

Some one should keep a log on the sound though. I think with it removed it can slowly get louder. The stock setup will get louder too but not as much as with it removed.

Question. Would it still work if i just removed the resonator and did not put any pipe going to the muffler, making the muffler just a cosmetic piece?

The part you are removing is the resonator. You need to make sure you get the parts correct. There was another member who dropped his car off and told them to remove the muffler and they removed the wrong part.

The "lunchbox" you can see from under the rear bumper this is actualy called the "resonator" a muffler shop considers this part the resonator. The muffler is actualy up under the middle of the car. Its long a tube shaped. WHat you want to remove is more square looking.

Make sure you get the parts right if you are having some one else do the work or they will remove the wrong parts.

If you ask me, the resonator is more restrictive then the muffler. So if you do anything just remove the resonator.

If your asking about just removing the resonator and not hooking the rest back up? I wouldnt, i would atleast add an extension so the exhaust dumps out the back. Fumes can come up into the back hatch if its open and running. I also dont think you want the exhaust charing the underside of the back of your car.

you could get the car from the factory without it so it should not be a problem.
