Are you saying it showed a different speed on your phone? Is it using GPS? I found my GPS lap timer shows a speed about 3-4 mph lower than my Boss. I'm trying to find one of those police trailers that flashes your speed to see which is accurate. I know my timer is accurate as it gives the same lap times as the tracks transponders. It's a 5 mhz unit so supposed to be accurate to 1/100 of a second. No idea about the accuracy of the speed......
Glad to hear you like the sound of the Corsas. I'll know on mine this afternoon. Interesting that you don't hear the side pipes. That must mean freeing up the flow through the axle backs is working.

The Corsas are loud under acceleration, very quiet at idle, the drone is not as bad as I made it sound after rereading my post, it's better above 69 mph.
Let me know how yours sound after you get a few miles on them.
Going to stop by MPH today for a look at the track.

I was using an app called CARDASHBOARD (Droid version) GPS, it was showing about the same as yours 3-4 slower than the Boss speedo.

Good to know about the Corsas. Since your speed limit down there on the interstate is 70 you're golden
My car's only long highway trips are on the back of the trailer so I'm not too worried either way.

Pretty much the same assessment as you. With the windows down on the highway (which is how they are almost all the time) I can't hear the exhaust. Windows up I can barely hear it with the radio off and a/c at the lowest fan setting. Most of the sound is out the back now. With the windows down I don't hear the side exhaust like I used to, but I hear the same sound out the back so it must be flowing a lot more freely as there was obviously still quite a bit of back pressure from the stock mufflers.

**sigh** could be. I hate to do that, but it's possible I will at some point. My first goal was louder from the back of the car so mission accomplished. I'm going to run this way for a while. I was going between some concrete barriers tonight and could hear the exhaust still reverberating from the side pipes. I think I'll sit tight for a bit. However, I did talk to my friend with the 5.0 that has these same Corsas and he made the comment that he should have held on to his stock H-pipe so I could shed the side pipe weight 
I'm sure someone will do it soon. I'd be curious to know how much they really weigh. Probably not 20lbs? The stock mufflers are heavy though! I didn't weigh mine since someone already posted the weights, but hauling that box up to my storage attic, it felt all of the 56 pounds and then some.

I love the exhaust now and its loud enough out of the rear you would never hear the sidepipes anyway

If I'm not mistaken I think a change to the mufflers will void the warranty. This is according to their TBS about engine issuses from tunes or componet changes which include air intake or exhaust changes. I wonder if this still applies to changing mufflers out to the ford racing gt500 mufflers on thier FRPP site. Still thinking about changing them out anyway.

Catless mid-pipes with tunes that turn off Rear O2 sensors, on the other hand...

I installed some Borla Stingers on the boss this morning. They sound awesome in conjunction with the open side pipes! The first thing I noticed when starting the car the first time, is the Borlas have the same tone as the side pipes, which I love. I was afraid there may be a lot of pop and crackle on decel, but fortunately, its nothing but the low pur-like growl like you get from the side pipes.
It's like having a Boss Symphony in surround sound. Love it!
As an added bonus, they look great with the polished tips, and the muffler has a much smaller cross section so they aren't really visible from the rear. According to my digital bathroom scale, they only weigh 10.4 lbs each, so that's over 30 lbs of savings from stock.

Just got the Trackey installed on mine with Roush mufflers. I love the pop and crackle on decel. If there isn't much of that with the Borlas it looks like I made the right choice
