Mercury Grand Marquis 4.6L V8: DYNOMAX RACE BULLETS Vs FLOWMASTER FLOW FX Vs STRAIGHT PIPES!

[@marcellusperry3878]

This is my first time knowing bout the Dynomax. Im a fan now. Im taking my other shit off. Do we really need 4 cats?..

[@BlackTownie999]

@@marcellusperry3878 some can get away with passing smog with only the front two, others cant...and some can do it without check engine light on and some cant...it's basically luck I guess.

[@SlikLizrd]

@@marcellusperry3878 YES. Our cars are fitted with four (4) Catalytic Converters because that's what it takes to GET our air clean, and we DON'T take them off to make MORE NOISE -- we keep them on to KEEP our air clean in the future. Unless you're stupid. Stupid people remove their Cats. They can't help it, because they're stupid. Early "Pan-Type" Cats used by General Motors and Toyota were shaky about clogging, and would often cause a power loss. Not so with the "honeycomb" Cats as used on Panthers. Ford has always used the "honeycomb" Cats, which (when new) can flow as much air as the straight pipe. I have run the DYNOMAX mufflers on our '92 Vic -- excellent performance and sound, with NO DRONING at any speed. Expensive, but worth it. Currently, the famous 95 MERC runs a Cat-Back system -- Walker H-Pipe; MagnaFlow # 18134 Glasspacks; Walker Tailpipes; Superior Tips. A smooth, powerful rumble -- and NO DRONING !

[@antoniok52]

Dynomax for me, had more volume and that super smooth deep tone i love.

[@phil955i]

With the H-pipe for me, sounds deeper. The straight pipes just sound obnoxious.

[@infinity3jif]

I like the sound of the 2nd car with the flowmasters

[@houstonradford3519]

Me too

[@AlbertLara-tc2bs]

Agreed 👍 Wht would it run me to do the tru dual after cats Go wit the Flowmaster setup, down to same tips Even the h pipe crossover?? I'm coing through Tennessee soon, I could swing by for your shop, due to these vids😉👌 Keep the vids coming and alll the great content!!!!

I'm pretty sure that's illegal.

[@yeanah2571]

@@makeumybitch they're in Tennessee, rules are different down there. Here in NY, if it's a V8 or a Harley, it can be as loud as you want. If it's a 4 or 6 cyl, it better be stock or close to it.

[@makeumybitch]

@@yeanah2571 what? That's a strange rule. Lol That's cool though.

[@makeumybitch]

I love my 06 Grand Marquis Ultimate edition.

[@shonoff83]

Personally I like a aggressive sounding muffler, but I think that the straight pipe setup sounded the best... to me.....🤔

[@GlitterGoose]

I ended up going with 2 Dr. Gas 5 Trap mufflers and the Dr. Gas X pipe for my 02 Grand Marquis. Sounds slightly healthier then stock at cold start and idle, but at WOT the exhaust sounds similar to the Dynomax example here.

[@noconsentgiven]

That flowmaster got out though💪🏻!!

[@TracksideTyson]

The cleanest looking setup was the dynomax with the x pipe.

[@MikeJones-gb3th]

Mines is straight piped and dumped it sounds like a beast

[@BradHuey1992]

Should of put super 10s on one of them. They sound good with them on. An my favorite was the first one.

[@LorenKyleDiedrich]

I would have deleted the secondary converters

[@HillBillyBrown]

I would have deleted all of them.

[@TA_392]

If the straight pipe guy took it off at the flanges, it would be the same loudness, but wouldn't have that blat-blat sound.

See I wanna see one with the 4 stock converters but with a x pipe flow master with Marauder tips

I don't like that stock shit that came with it so i want your honest opinion what should i do

[@alainmarquez2290]

Hello guys from EXHAUSTADDICTS. Did you ever try true dual with Flowmaster Flow Effects mufflers in a Grand Marquis?. How that sounds? I want to have a nice V8 rumble, no grasping or to much popping. Thanks much for your time...

[@andrewhamilton1024]

All the way in Tennessee is a far drive. But for my Vic I might just make the trip.

[@shittywheelies7403]

Boss if you just get the parts you want to duplicate from the video pretty much any exhaust shop can get it set up for you

[@edwardmyers1746]

Dudez got an 06+ bumper on a 03-05 marquis lol, at least do the grill and headlights too.

[@andrewhickman28]

Straight piped hands down . Obnoxious is the ticket 😂

[@wydopnthrtl]

Here is what I want... at light throttle I want the dynomax. At part throttle I want the flowmasters. And and WOT I want the cats gutted and straight pipes. Between these three if I had to settle for only one.. I'd go with the flowmasters.

[@davidlastoria3341]

Borla? Wondering in comparison how those sound.

[@SlikLizrd]

Somebody has a video on a Grand Marquis with a full BORLA exhaust. I liked the sound -- sounds like power, not like stupid.

Correct me if I'm wrong....,,,,, Isn't that called a cat back exhaust straight pipe is from the motor all the way back with no mufflers no cats no bends pear straight pips ..

[@thegod625]

Those flow masters sounded it lower which is better

[@ESPLTD322]

I’d say Flow FX, simply because it sounds better at idle, but Dynomax is very, very close. Straight pipes are good but too raspy, which is why I’m not a fan of straight pipes on V8. I like them on V6s though.
