Hello everyone:

OK...just got my new 2012 Wrangler Sahara 2-door...

I love the new PentaStar V6...but, sure enough, the FACTORY LOG-SIZED muffer muffled most of the 'good noises'!!! (why is such a huge, heavy muffler necessary?)

So, as on my previous vehicle - off to my favourite exhaust shop...

I'm very happy with the sound (and the look) of the new stainless steel MagnaFlow muffler and stainless steel tip...It's very quiet at idle (almost as quiet as the OEM muffler!!)...but, when you press the 'loud pedal'...what a difference!

Nice throaty growl on acceleration...and the one time (so far) I've done a full throttle acceleration with my 'just broken in' motor...wails like a 'banshee'...I recommend this sub-$300 modification for those who want to not just feel the performance improvement with the new engine...but HEAR it, too!

I am debating on whether or not to remove the factory 'middle muffler'...but I think I'll leave it on for now...

I'm thinking of changing mine too, what did you do with the tip? Did you leave it the same or did you put a bigger one? What do you think of changing the position a little?

Hey I was thinking about the Magna flow as well but a fellow jeeper installed his and said that it was really loud on the highway. To loud in fact. Sure appreciate you views on this.

Will installing a Flowmaster / Gibson exhaust system void my vehicle’s factory warranty?


There are some modifications that have the potential to void a vehicles factory warranty, but properly modifying an exhaust system after the catalytic converter is not one of them. The Magnuson-Moss Warranty Act was created in 1975 to protect consumers from invalid denial of warranty claims. Under the provisions of the Magnuson-Moss Warranty Act, an automotive dealership/carmaker cannot void your warranty simply because your vehicle has been modified with aftermarket parts. They (the manufacturers) have to prove that the failure was the direct result of the installed aftermarket part. Unfortunately, too many people have gone to a dealer to have warranty service performed on their modified vehicle only to have the dealer refuse to cover the unrelated defective items. The dealer usually states, that because of the aftermarket parts installed, the warranty is void (without ever attempting to determine whether or not the aftermarket part caused the problem). If in any case, the dealer just lifted the hood, saw the modifications, and stated that the warranty was void based on what they saw (without verifying that the failure was due to the aftermarket installation), the dealer would be in violation of the Magnuson-Moss Warranty Act of 1975. The cause of the failure must be searched out and proven in order for the carmaker to void a warranty. If you’re having problems regarding this issue, please contact the Specialty Equipment Market Association www.sema.org for more information regarding consumer’s rights in relation to performance aftermarket parts.

I have an exhaust, cold air intake, and of course the lift and stuff and my warranty is still in tact.

saharaguy... Is your new exhaust same shape as the factory one or is it higher clearance? Im looking at changing out my Gibson because i have it smashed apart and its sitting crooked from use on the trails.

Too bad that MM doesn't apply to Canada since it's a US law.

From my London, ON. Jeep dealer today.
Question was:
' I am looking into a Gibson Cat back Exhaust [2 tips]
I don't expect it will affect the warranty. My understanding is any change past the converter is OK.
Do you have anything you can send me to verify any that it will not affect warranty or if it does.'

Answer to question,
"Not warranty friendly but won't void Jeep warranty.
Example : A/C stops working still covered
Radio stops working still covered
Muffler over heats or rattles , not covered , it has been altered."
