Thumbs up A 2011 Shelby Mustang Axleback Testimonial

OK, I bought these from Latemodel Restoration Tuesday night. I received them Friday afternoon, and installed them yesterday morning.

I paid $285 shipped to my door. After I ordered I found other guys getting them a little bit cheaper, but did not want to go through the hassle of cancelling one order that shipped almost as soon as I ordered, and creating a new order for just $10 savings.

Took about an hour and a half with normal hand tools, and a set of composite ramps from O'Reilly's Auto Parts. I jacked up the car using a piece of wood under the axle center section, and slid the ramps in under it. I didnt trust driving up the ramps in reverse..... Once under the car, I loosened the muffler clamp, and I had to loosen and partially remove the mid-pipes (unbolted from front clamp, and slid out and moved out of way). Also, while installing the driver's side muffler, had a hard time getting inboard (closer to center of vehicle) hanger into rubber mount. Solved this issue by cutting just 1/4 inch off of hanger with a hacksaw, and everything went in just fine.

Overall install was very simple, aside from the minor hanger hickup, which had a simple solution. Anyone else run into this??

Now for results. I will not be posting videos, as there are several already, AND, I know the equipment (cameras) that I have will not take good video with sufficient sound.....

On first fire-up, it had a nasty, mean sounding snarl. After it warmed up, it quieted down to a beasty rumble at idle.
Acceleration, from inside the car, sounds intense, and hardcore! I have the 6spd manual, and decellerating in gear sounds racecar-ish from inside vehicle.

I will agree with what some others have posted before - that these mufflers are what the car should have come with from the factory. They sound sweet all the way around, AND, you can add me to the 'No Drone' club involved with these mufflers.

The 4 inch tips fill in the factory bumper/rear valance soooo much better than stock.

In closing, I will say that I will recommend these to anyone who wants a solid sounding muffler system, that has a great sound under accelerating load, a fun and mean sounding decelleration tone, a meaty idle rumble, and No Drone.

Sorry for the long post, and thanks for reading!!!

I also had a hell of a time getting the driver's side in the mounts. From what I've heard, it's much easier if you loosen the midpipe clamps.

I just wrestled with it until I got it to go in.

Glad I could help you guys make your decision!! Ill tell ya, my plan initially was to get these first (due to price), and if for whatever reason I didnt like them, I would get something else! Well, I plan on keeping these. I have had them in for about 27 hours, and I have put about 150 miles on my car, just so I can hear them!!!

Yeah, I did do that! I had the driver's midpipe laying on the ground, and still could not get it to go in!! My panhard bar was in the way....

I THINK it would have been easier if I had jackstands that were on the body, which would have let the axle hang down, thus moving the panhard bar giving more clearance, BUT, of course, I didnt think about that until after I trimmed the hangar and had everything put back together!!!

Yeah, one of the best parts is that its not obnoxiously loud. It turns heads still though

It doesnt have any raspiness that can be heard from some of the more hollow, or 'straight through' type mufflers that I have heard before....

These are the best street mufflers out there for the 5.0. Cheap, high quality, great fit, great looks, and great sound. I don't think they can be beat. Had Borla Tourings and they are also great quality and looks but little drone and just too loud during cruising for me. With the GT 500s you can stay quiet at part throttle but make some noise when you want too!

I agree - for the price, and the fact that you are getting OEM, its hard to pass up!!

I did just hear from a fellow member via PM that Latemodel Restoration is on temporary back-order with these mufflers......
