Your cart is empty.Flowmaster's Super 44 muffler uses the same Delta Flow technology found in our larger Super 40 mufflers. The Super 44 delivers a powerful rich tone and is the most aggressive, deepest sounding, highest performing four-inch case street muffler we've ever built! Constructed of 16 gauge aluminized steel and fully MIG welded for maximum durability.

I'll start by saying it sounds great.no dents or dingsonly small complaints1 being the one I got the inlet is offset unlike the pic where its centered.2 the inlet is a 3" OD not 2.5" like the add states. but like I said those are minorI will say if anyone buys this and has never had a brand new painted muffler there will be a burning smell for a little bit I freaked out when I smelled it so went searching and found smoke coming from the muffler so I just figured thats the new muffler smell lol. all in all good product and good buy

Great price and fast shipping..came earlier than expected..got it installed on my 2010 chevy silverado 5.3 v8..i got 2.5 in and dual 2.5 out..the muffler is universal and can be ajusted to fit any truck..my stock muffler was a 3inches in..i added 2.5 dual pipes and 4 inch tips..it gave it an aggressive sound..when in idle it has a deep rumble..the dronin is not noticeable and does not interfere with coversation or music..oh and when you hit 2000 rpm thats when u hear the sound of freedom..

This was a great buy at a great price!! I installed on my Lincoln Navigator, and it gave me all the sound I could want!! Just ended up doing an axel drop for now, but the sound is not totally overwhelming. At idle the sound is a nice rumble, but when you step on the gas......that's when it opens up, and howls with a sound that will turn heads!!Absolutely love what it's done for my Navigator, brings out all the great sounds a 5.4 DHOC Ford engine can make!!

Despite that this muffler is a generic Chinese knock-off (made in China was stamped on the box) and not the real American-made Flowmaster muffler (almost all the top name mufflers like these that they produce are built in either Mexico or Canada, which is still considered America), it does do the purpose it was built for. Produces a nice growl on highway drives, not too loud when cruising through streets but pretty loud when full throttle is on. Bought if for my 2017 F150 Coyote V8 Crew Cab short bed 2WD. Running 2.5 inch pipe into the muffler and 2.25 inch duals out the muffler (technically making it equally the same flow rate as a single exit 4.5 inch or 5 inch exhaust) with 3.5 inch exhaust tips. Truck has no catalytic converters but still has stock resonator for now. I'll maybe buy a high performance resonator later on but more than likely will do a resonator delete. Happy with the condition of the muffler and how it does with sound, just wish is wasn't a knock-off made to look like the true Flowmaster.

Came quickly and was exactly what as t I ordered. This replaced a cherry bomb extreme on my 05 Hemi Ram. This is much quieter at idle but definitely noticeable during acceleration.

Very fast and great shipping times! Apart from that, the product performs as it should without any problems. I would recommend this to anyone who wants to upgrade their truck/car exhaust and be noticed when coming down the road! It has a very deep rumble undertone as well as well as the raspy "yell" when you mash the gas! Very well made and very well worth the money!

Cut out old muffler on my 06 Silverado 5.3 L and installed this with 2 turndowns right off the back. It sounds awesome and very tolerable on the highway.
STILL HERE !! 😊

This muffler is exactly what it says, and is the best overall sound I have ever had with one.I have had glass packs and magnaflow before but too tame for me !
