Turn's your girl Jeep into a man Jeep !
The media could not be loaded. Bought this for my Manual Transmission 2005 Jeep Liberty Renegade... Total project was about $300.00 ... was turned down by two local muffler shops... due to brake lines on the driver side rear axle... had to take to a local welder, and talk him into running both pipes on the passenger side... He said it was a tough job... but I think that's just because they did it right... Less than 6hrs had my Jeep back... You can't tell from the audio but idle makes a huge difference... Sounds like a man's truck... Sound's great taking off from a traffic light, definitely bass in the exhaust now... but I can still drive up late to church on Sunday and not be embarrassed by how loud it is... Really man's-up my girl Jeep... But arn't they all girl jeeps lately!!! Haha - my first impression is... it's well worth the money for the total project...( Oh, one more thing, it's not loud inside the Jeep, researched several posts before I bought this and it was mentioned some sort of an exhaust whine... at cruising speeds, and they couldn't hear their radio... Maybe they have automatic's ... maybe they didn't pay to have it installed professionally... With a stick I just shift up... the little bit of noise on the high side of the gear is gone... Took it on the highway 6th gear... Not bad at all... I Could hear my radio at the lowest volume setting the whole time... ) - Buy this for your Girl Jeep ! - make it a Man Jeep !

good product small complaints
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

Sounds good. But not a true Flowmaster.
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.

Aggressive with a deep rumble
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..

Good sound not obnoxious at idle
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.

Nice at idle, Wild on the throttle!
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!!

Sounds Awesome
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.
