Flowmaster 40 Series Delta Flow Mufflers Reviews

This muffler is great, dont get me wrong but the representatives did not know a thing about my car, although the said they did. I sent back and order a new muffler that they recomeneded two times before i had the right one. The car sounds great and has a very deep tone to it. Not too ricey at all which is what i was looking for. It has the loudest tone to it at about 2000-2500 rpms. The muffler was extremly hard to install and remember to get it bigger or smaller than the pipe on your car so that it may slide on or in and make it easier to weld. I am decentlt happy the way it turned out. (3.5 out of 5 stars)

Gibson CFT Oval Superflow Mufflers Reviews


Sounds amazing!!!

Reviewed By John S (MYRTLE BEACH, SC) Reviewed for a 2013 Toyota 4Runner —5/11/2018 12:09 PM

I used a local muffler shop to install this, they did a good job though. My gas mileage has increased a good bit as well had an incremental increase in power and torque, it's hard, really, to gauge these without a dyno. It sounds great, everyone loves it. Most say it "sounds nothing like a 4Runner". My only complaint is the baffle within the muffler as this is a single entrance and exit muffler but the muffle itself has a dual chamber construction inside. Noise will be fixed with insulation.

Sound

Reviewed By Homar B (Artesia, NM) Reviewed for a 2006 Ford F-150 —5/11/2018 6:31 AM

Upgraded my 5.4 3v F150 from 2.25" true dual exhaust with Dynatech max long tubes and cats with super 40s to 2.5" with high flow cats and super 44s. The sound isn't as loud but more throaty with a little more rumble and the interior resonance was reduced drastically. Exhaunt flows much better now. I can't tell if my low end torque changed much but passed 4000rpm there is a big difference.
