Incredible Tone and Performance-SEE UPDATE

I was originally hesitant to buy the Outlaws and was leaning towards the American Thunder Classics because people kept saying how loud the Outlaws were and clips I listened to supported that; I also had a CAI and tune on the car which had already enhanced the exhaust note so that raised more concern that it would be overly loud. But, at the end of the day I figured I'd rather it be a bit too loud then be a bit too quiet and be disappointed. And that was the right decision. The Outlaws are loud-though to my ear IN the car they don't sound that loud-don't get me wrong, from stop up to pick your RPM, if you're accelerating you hear these and you hear them good. At idle you hear a decent grumble at all times which is exactly what I wanted yet once you're not accelerating any longer all you hear is a light exhaust note in the car (and I mean LIGHT); the only time these "drone" at crusing speeds, which I happen to like BTW, is at 80 mph and above or approx 2300 RPMs and up. Now, like I said, I have an Airaid CAI and a Steeda tune so the note is even more aggressive than stock but I'm still considering either a catted X Pipe or Off Road X Pipe. My primary concern is I DO think an O/R X pipe with these would be really loud and perhaps too much so for daily driving but I would imagine a very aggressive but tolerable tone with an X Pipe fitted behind the cats. 4 WEEK POST INSTALL UPDATE: The Outlaws are LOUD after about 3 weeks of break in-do not buy these if you don't want heads to turn, your neighbors to make "friendly" comments about your new exhaust, random women to stop you in parking lots and an extra couple notches on the stereo to hear your music. Anyone that is reviewing these and is saying they are not "that loud" have either not installed a Cold Air Intake and/or tune OR they haven't let the Outlaws break in (or they are possibly used to something even louder like Pype Bombs or simply an older car with no mufflers at all). On cold start up with my garage door closed my garage windows visibly vibrate; at wide open throttle these SCREAM-I mean many muffler get quieter after 3000 RPM's, these get LOUDER. I reqularly have people walking AWAY from me on sidewalks nearly a city block away turn and look at me and that's with me light on the throttle under 2000 RPM's. A friend the other night told me he could hear me obnoxiously so as I drove by a local Starbucks-and he was indoors. I've been stopped by two women totally cold in parking lots just this week after I pulled in under normal, light driving conditions to comment on (as one put it) the "pure sexy" that was the sound-my best friend (also a woman) heard them for the first time last week and proclaimed "THAT'S a panty dropper sound". And with ALL that said if you need to keep a low profile, you can but you need to be easy on the throttle and go slow. And that's EXACTLY what I wanted-but not everyone does want that, so you have been warned. When I first put these on I considered an H Pipe or X Pipe to add some kick to the sound, but now I'm glad I waited for the break in-these would be UNBEARABLE on a daily driver with a CAI and H/X pipe. Finally, the "drone" that so many complain of is now very present at any speed over 55-and its always right THERE at 70 and up. Frankly I'm not sure why people don't like that-maybe some have more sensitive ears than me or maybe its just a difference in preference and taste; personally, I want to always have that reminder that 400 HP is 18 inches from my toes on the other side of that firewall...and this exhaust is quite clear about that. I few installation notes: installing these requires jacking the car or preferably putting the rear end of the car on ramps. That along with a socket set is really all you need to install these. One caveat is that you MUST have deep sockets to fit over the bolts AND the extender. It also wouldn't hurt to have a socket wrench with an extendable handle. The biggest issue is the hangar bolt on the forward hangar that is ABOVE the muffle and on the body...you have to remove the other hangar and get the exhaust nice and loose so you can shove the wrench up in there to loosen it. Once the stocks are off, installing the Outlaws is incredibly easy. Total install for anyone remotely familiar with working on cars should take one person about 2 hours max with the hardest part being removing the stock mufflers. The fit and finish are first rate and shipping was quick and well packaged (though I found it amusing that the mufflers are manufactured at the Flowmaster plant 10 miles from my house and were shipped across the country twice to get to me). Pricing was excellent with the 25% off promotion, shipped for under $300. Overall I am VERY pleased-the Outlaws give the Mustang that muscle car sound with a nice deep rumble that is the Flowmaster signature and loud without being glass shattering loud. Highly recommended.

Excellent axle-back exhaust

I researched axle-back exhaust for about 2wks, had these in my cart for about a week before I pulled the trigger. I am so happy that I went with these, they sound absolutely amazing on my 2005 GT. Everything else is currently stock on my car, these are definitely louder than the stock axle-back exhaust... But don't believe all the hype about setting off alarms and becoming a police magnet...in terms of exhaust note and volume level, these fall perfectly in the center of not being loud enough and being obnoxiously loud and offensive to neighbors. The exhaust not is nice and deep, you can slow roll through your neighborhood and not bother anyone...but if you stomp it they ROAR! The install wasn't bad at all, we just set the rear of the car on ramps and had plenty of space to work. The driver's side is more difficult to remove than the passenger side...maybe took 2 hrs total with a break included. Honestly could not be happier with this purchase. If you are debating buying these Flowmaster Outlaws, just go for it...you won't regret your purchase. I'm certain if I'd purchased the American Thunder series or any others I would have been disappointed. These are spot on perfect and make the S197 sound exactly as it should, like a muscle car.

2010 Mustang GT - Excellent throaty sound, installed with no problem.

Very good, deep sound. In my opinion not too loud by any means. Gives the Mustang a nice, aggressive sound to match the looks. The hardest part of the installation was removing the original exhaust pipes/mufflers. It took some penetrating oil and muscle to get the original clamps off and to separate the rusted sections of pipe. If using a socket by hand, do yourself a favor and use a long pipe over the socket wrench to provide a lot more leverage. Once the OEM mufflers were removed, the Flowmasters fit perfectly, the hangers were in exactly the right position, and the exhaust tips were perfectly centered in the bumper cutouts. Great sound, easy installation, and I would absolutely purchase these Flowmasters again.

Very Pleased

I put these on my 2010 Mustang GT convertible, and they are so much better than the factory mufflers. The installation only took me 2-3 hours, and I didn't even bother putting the car up on ramps. The hardest part was removing the stock mufflers. Once that was done, the actual installation of the Outlaws was much smoother, as they are smaller than the original mufflers, giving you more room to work. These things are loud to be sure, but they are not overpowering or obnoxious. I had toyed with getting the American Thunder series, but was afraid they weren't much different than the factory mufflers. Very glad I went with the Outlaws. They sound great, and there is very minimal drone. Guaranteed to make you grin when you start your engine.

Low RPM Rumble

I recently returned the Pypebombs and received the Outlaws yesterday and bolted them on last night. I am loving it. Low tone rumble when cruising and a kick in the face when I open it up. Precisely what I was looking for. I didn't have to tweak anything around to make sure both sides were centered out of the exits. So much easier than the pypes were.and so much better quality in the FlowMaster brand name. Took me less than one hour with literally with one arm (Shoulder surgery recently on left side) but I hope that paints a clear picture of the ease the Flowmasters provided. The sound is awesome and not obnoxious like the pypes were for me. If you disagree, read the reasons why I returned the pypes on my Pypes pypebomb review. How about a manly tone and rumble when cruising or idling rather than just a freeflow of s*** flying everywhere when idling or cruising? Outlaws is the way to go.

Loud and expensive

VERY LOUD if thats what u want paired with an off road x pipe. Very raspy with no cats. Had to take em off they were so loud. Be perfect with the stock h pipe. Installed on a stock gt500 and sounds perfect. Overpriced for what they are. Basically just a resonator. Shouldnt cost more than 250

Honest Truth

K, so u if your planning to buy this set of flowmaster sets, and u read some of the reviews, u see that alot of peoples reviews seem to be way out of control, calling this set to be super perfect with the perfect sound. Well im here to tell you that those reviews are completely true..This are GREAT, Easy to install, 30-40mins basic tools, and the sound is AMAZING, yeah..maybe the word AMAZING is short for how great they really are. But ones again, im not a super tech guy or someone trying to sell u this stuff, just your average JOE trying to get his car to sound nice(06 mustang GT) and i really do love the sound they produce, how easy the install was, I actually installed these without having to lift the car or set it up on a rack, was parked on drive way , and decided to give it a shot , BANG, done, only 4 bolts per side to take off and place these new ones in. LOVE EM they are well worth every single penny!!!

Expect your car to come alive.

After about 2 weeks of trying to figure out whether to stick with what I know for sure or try to go with something new I stuck with my heart and chose these. I cannot be happier I think. This is my second Mustang and this is my first upgrade on her... and man man man what can I say .....it's alive!! The sound is perfectly aggressive when accelerating and idle. People definitely notice a difference. Now my 2006 Mustang GT sounds like the pony she is supposed to. I'm excited about this purchase. My neighbor and I only took about an hour and a half to install them but mostly because we did a lot of talking instead of working. Easy install. Go Flowmaster you've done it again. And if you wondering if you should buy this then yes you should.

A BEAST

The sound is awesome! The product is well made. Highly recommend. Also, I am not a mechanic and do not do repairs to my own vehicle. However, my 16 year old son and I installed this together. Easy instructions.

Sounds great

Easy to install and sounds great. Had 2.5" H-pipe and Magnaflows, replaced the Magnaflows with these and it sounds great. I have minimal to no drone which was somewhat a welcomed surprise.
