My local dealership is an authorized Roush performance center. I discussed with them and they stated...if the parts are bought through them and they install, it will not affect the manufactures warranty and will be covered under the ESP once the 3/36K runs out.

Exhaust can also effect the turbos and engine, so the engine and turbo warranty may be voided also. All depends on your dealer, go talk to them to find out.

OP has 5.0...

JPCharmin

my dealer said i can put a catback on my 5.0 and it wont void the warranty, whether its installed by them or not. You really have to check with your dealership, most people swear up and down that a lift, catback exhaust, etc. will void your warranty but it depends on your dealer. ****** my truck came with a lift, 20's and 35's under factory waranty! what you gotta say bout dat lol

I mean the truck's 3/36,000 bumper to bumper and its power train warranty .. I dont care if the exhaust has a warranty if it rusts out i'll talk to roush about it ....

I just dont want the dealer to say this when i have an issue -

EXAMPLE- I have warped rotors due to manufacturing defect

DEALER SAYS- Sir you have a catback exhaust which qualify's your truck to compete in the NHRA so you are clearly racing and after every pass you are locking up the brakes therefore your entire warranty is voided and we shall burn you on the cross.

G2G

Ford Corporate has clearly indicated that dealers must prove that an aftermarket part caused the failure.

LITTLE BIT OF DIGGING BRINGS THIS BACK TO TOP AGAIN.
if you look at "harware modifications" listed in this TSB exhaust and air intake mods are both listed as thing to look for and could cause warranty voiding. the best thing you can do is go to your dealer and discuss it with them. tell them you are interested in doing this. they will tell you if they will cooperate and if they do agree to cover it GET IT IN WRITING on officiall dealership letterhead and make sure its noted in the FORD system that they approved it to not void facvtory warranty.

Ford issued a TSB today for F-150 and Mustang vehicles with the 5.0 L V-8 telling dealers to watch for engine modifications.

The TSB includes pictures of pistons damaged by aftermarket tuners, very similar format to the Ecoboost TSB, along with a flow chart indicating when the dealer should cancel the warranty.

The flow chart does show that the failure must have been caused by the modification in order to cancel the warranty, so same as always - just be aware that Ford has provided the dealers with a very specific list (including detailed pictures) of what to look for to find tuned engines.


Here's the text of the TSB (#11-7-7) - note that there are pictures and diagrams in the actual TSB that aren't shown here.

ISSUE:

Some 2011 F-150 and 2011-2012 Mustang vehicles equipped with 5.0L engine may have unauthorized modifications to the powertrain hardware and/or calibration which may result in exceeding component design limits. Such modifications could cause damage to the powertrain and/or void the factory powertrain warranty.
ACTION:

Follow the Service Guidelines.
SERVICE GUIDELINES



Inform owners that the current 5.0L calibrations adjust fuel and spark settings for maximum performance with production hardware, while protecting the engine over a wide range of operating conditions. This includes a knock sensor calibration enabling optimized performance based on fuel grade usage see Owner's Guide for details. Aftermarket hardware and calibrations risk damage to the engine.
Unauthorized calibration modifications may or may not be detectable using standard tools Integrated Diagnostic System (IDS), Portable Diagnostic Software (PDS), NGS+ VCM. Changes can be made to the calibration and flashed to the powertrain control module (PCM) through the on-board diagnostics (OBD) port. Physical modifications to the hardware may or may not be present. If aftermarket power/torque-increasing modifications are suspected, care should be taken to record and store the following items: Permanent diagnostic trouble codes (DTCs), pending DTCs, freeze frame data, mode 6 and mode 9 data. The data should be printed and attached to the repair order for later reference.
The DTCs, freeze frame data, mode 6 and 9 data can be obtained by using the IDS, PDS or NGS+VCM under tool box selection. The powertrain tab will provide the OBD test modes tab and mode 6 and 9 data selection after the vehicle has been identified.
Attempting to increase the engine output via recalibrating the PCM may result in poor drivability, DTCs, or component failures. A partial list of calibration induced component failures is given below: Excessive Cylinder Pressure And Temperature

• Piston damage
• Spark over-advanced (knock-induced damage)
• Insufficient enrichment
• Catalyst damage

Increased RPM Limit/Overspeed

• Piston damage
• Connecting rod damage
• Oil pump damage
• Catalyst damage
• Clutch damage

Knock Sensor Calibration Changes

• Piston and/or ring damage due to improper knock control

Hardware Modifications:





The following list contains items that are frequently modified in an effort to increase the engines torque/power output. Modifying these items may, or may not improve the performance, but can lead to drivability issues, DTCs and possibly component failures:

• Air induction system (air box, air filter, zip tube)
• Super chargers
• Nitrous oxide systems
• Throttle bodies
• Exhaust air path/system

Review Engine Damage:





Common failures associated with unauthorized modifications have included:

• DTCs present indicating cylinder misfires (P0300 - P0308)
• Cylinder/piston damage resulting in a misfire, low compression, noise
• Unusual Clutch wear/damage
• Piston damage - light knock (Figure 1)
• Piston damage - heavy knock (Figure 2)
• Evaluation Guidelines Chart (Figure 3)

Looks like the warranty questions has been answered. As for price I would expect 1.5-2.5 hours labor for the job. Based on $110 an hour thats $165-$275 for install. This is based on installing an exhaust on a mustang here in Canada.

NickBottoms

talked to my dealer and getting the exhaust tomorrow

They said - We dont care what you do with you exhaust cut it off for all we care , just dont touch the cats.. also he said without me even bringing it up " if you install a tuner however your warranty will be voided no doubt.
