It's in the dealers getting striped, exhaust, etc. Took it around there place for a few minutes. Didn't notice drone but didn't have much time driving steady at low rpm. They will be done toward the end of the week and I'll be able to say more then.

wolfman11GT,

Congrates,, hope it turns out to be what you were expecting..

if possible it would be great to get more pics of them on the car and the tips showing out from the bumper..

then of course, a sound clip would be much appreciated and your impression.

I am most concerned with them being all around too LOUD. I am hoping that’s NOT case.

When I listen to the clip on these , to me anyway, they sound like the Borla ATAK which may be a bit more” raspier” if that’s even a word, then I want when on the throttle. Hoping its really more of a deeper rumble when your on it then raspy .

good luck !

Stripes done tomorrow and I'll have it back end of work day. If all goes well I'll be able to go for a drive. More pics and sound clips possibly.

Put mine on last night. Took a hour. First impressions are it's loud when you're on the gas. Quiet while cruise and idle. No drone which is awesome. It is a little raspy when cold and 5000+ rpm. It sounds like no other v8 I've heard except for some European engines. Pretty cool actually. Rumble down low and screams up top. The raspiness isn't horrible like a ls1 with cutouts. It still mellow and refine sounding.

Installed mine 2 days ago. The various posted sound clips do not do the Roush axleback justice.

you guys that put this on yourself, was it easy or a hard job. The instructions that came with it are lengthy, do you actually have to remove the bolts that are up to the hpipe assembly? mine are sitting in my trunk right now bc i dont have time to put them on its dark when i get home and i just wanted to know if i could do this myself saturday or just let the dealer to do it saturday im guessing its 100 bucks. So do it yourself or spend 100 bucks and let them do it??

I just loosened the h-pipe. Definitely helped. The passenger side was easy. I had a heck of a time getting the driver side to move forward enough to slide out of the rubber gromet. Took about 45 mins to get it to slide out. About 1.5 hours total.

It took me about 40 minites jacked up the car took the bolt out that holds the exhaust together never even touched the mid pipe slid the muffler right out with some lube on the rubber hangers wd40. A little yanky enginuity helps to.

well i just want to be careful and not "yank" anything on those pipes, would hate to accidently bend one unknowingly and then wake up and have a valve problem. Ive already tried removing mufflers once before without loosening hpipe and a tidal wave of complete fail hit me

hi its now one week i had my mustang and i install the roush axle back the same day i think that they are the best mustang sound that i ever heard if you want to go unnotice you can by being very gentle on the gas pedal and you can make the head turn if you want but bottom line they sound incredibly right for a mustang its like a nascar if you want do not forget that the 2011 exhaust is quite freeflow compare to the 2010 so you need only the axle back to have a mean sound on a 2011 its hard to figure how much the sound change with the roush exhaust i suggest them highly with the 2011 mustang first time i heard them i almost took them off the day after but now they will stay there as long as i own the car :laughlitt

Well I've gotten some time with them in different conditions.

Highway at 65-70 I'm impressed. On a flat there's a mild rumble that you barely notice. Up a hill just keeping same speed the sound comes up a bit. rpms are low in 6th there is plenty of power but you still get a lugging sound. No drone.

Standing behind the car it is loud, even at idle. Nice deep sound. With some rasp and pops coming off higher rpm.

Sound inside is completely different. Not as deep.

Bit of an odor. Assume oil or something from manufacture is burning off. Seems like the sound is changing a little deeper after some miles. Might be in my head too.

Still not 100% I want something this loud permanently but they are fun at the moment.

i think he's referring to pulling the exhaust manifolds off the ports on the heads exposing the valves to cold air when scavenging.

edit: waiting for someone to quote me providing some link of another person saying it's impossible to happen even though i didn't say one way or the other.

Guys, don't have any anxiety about installing these yourself. This is the easiest exhaust you'll ever work on. Everything is designed to be removable. No cutting, welding, or other gymnastics. You can't screw it up.
