I installed a pair of Delta 40 Series onto my 2016 Mustang GT this December and it sounds incredible!! I also had the Ford performance X-PIPE already installed and with this combo, you cannot go wrong. Plus I saved at least $ 1,000.00 by not falling for those high-priced complete exhaust systems. All those compliments can't be wrong. Flowmaster is the way-to-go!!

Just what I expected !!!!

I had the resonator and muffler (which are connected stock) Cut out and replaced with the 40 delta. The sound gave my ford explorer A much more aggressive tone with the 4.6 v8 and it doesnt drone at highway speeds. Worth the money.

my local muffler shop put it on in an hour, its alot smaller then the stock muffler so i didnt want to mess with it. Has a mean growl on the exterior, with little interior noise, which is the reason i went with this muffler in the first place! I am very happy and would recommed it to anyone! the only thing i would do differently is get the dual outlet for a louder/meaner growl!!

I really enjoy my new muffler. The sound is awesome, nice deep tone :). makes my 2001 dodge durango look and sound tuff. only thing that bothers me is that they didnt have the muffler in stainless steel but in aluminum, its not that big of a problem though because flowmaster change their warranty to 10 years. but other wise really great product would recommend to anyone.

nice sound

this 40 series has a very nice external sound but does get loud on heavy throttle. interior resonance is a bit more than anticipated on pullout but very minimal at cruising speed.

Great Build but Excessive Drone

I installed this muffler on a 2007 Dodge Charger. I had to replace it with a Magnaflow muffler instead due to the amount of drone it created.
