Yup. my 2012 Boss was the same way

 

Yes...factory..... Both bent/smashed on all the cars.....the other one has the dent on the top.

 

OK, I have to ask. I have the extended warranty, will going to 500 mufflers and cutting out the resonators VOID the WARRANTY?

 

Best thing to do prior to any modifications -- get the owners manual and read through the clause about modifications.

quick answer is that if you mod your suspension, the suspension and related components which may be affected will not be covered.

if you mod the exhaust same applies. Bad thing is if you have a problem powertrain wise they *may* ask you to bring the car back to stock to perform diagnosis.

whatever you cut out of your car keep in case you need to re-install at a later date.

as for a general rule exhaust mods do not VOID your limited or powertrain coverage. But it also depends on the service department you're dealing with.

 

you will only viod the warranty on the exhaust system.

 

Just for clarification -- this is what is contained in the warranty agreement between you and Ford Motor Company.

Damage Caused by Alteration or Modification

The New Vehicle Limited Warranty does not cover any damage caused by:
• alterations or modifications of the vehicle, including the body, chassis, or components, after the vehicle leaves the control of Ford Motor Company
• tampering with the vehicle, tampering with the emissions systems or
with the other parts that affect these systems (for example, but not
limited to exhaust and intake systems)

As part of Warranty Policy and Procedure the manufacturer must list a "causal part"; in other words a part is deemed failed or subsequently failed-- what actually caused the part to fail?

Now if it is found that the removal of a factory part is the root cause -- then viola! no coverage.

I get this question at work -- when a customer wants to add a mod. I don't instantly tell him that BMW will void his/her warranty, but if the part that you decide to add causes a failure -- you are on your own. So when guys are out bargain hunting for a turbo tune that causes detonation under boost conditions -- and cry when something goes wrong, i have no compassion.

btw: I know we are not talking about BMW -- I have administered warranty for Infiniti and Mercedes Benz also -- unless there is something that Ford does radically different 90% of car makers follow similar guidelines.

 

Does cutting out the resonators increase horsepower or does it just change the sound?

 

Just changes sound, only exhaust mods that are inns make any noticeable increase are hi flow/no cats and some sort of headers

 

FWIW, Sean from AED tested the JPC ota pipes over on SVTP and picked up 6hp/7ftlbs at peak and about double that in the midrange. When you see how much the diameter pinches down at the resonator welds, you'd think they would be worth even more power

 

Thanks for the answers!!

 

I am once again contemplating removing my resonators....

Seems like a cheaper solution to getting the boss quad pipes.

Am just so worried about drone though...

 

there is zero drone. I repeat, zero drone.

I've had my resonators cut out for well over a year now and love the sound with the GT 500's.

 

Do you have a sound clip, fake?

 

I heard the resonators make the car sound rice-ish at high revs. Is this true?

 

Yes the GT500 exhausts are simply awesome. They sound great!

 

You mean removing them?

 

I just had mine cut out this morning and it sounds awesome. Not terribly different or louder but under high load and higher RPM, it's definitely louder and the tone is better. Putting around town at low RPM, it sounds a bit deeper and more mustang-ish.

 

You heard wrong. More like louder and deeper at high revs.

 

this is the only clip I have of my car with the resonators removed. I don't have one with me driving.

 

This guy who filmed his car is the best for comparing what the GT500's sound like without resonators.
