Slightly off-topic, but it looks like you did 0-60 in 6 second flat!

Oh man that sounds nice! Always wanted to get a Corsa system on all my other vehicles and think I am going to finally pull the trigger with the Jeep.

Any complaints? Drone? Thanks for any input and posting the clip.

The only done is for a brief sec on highway when MDS kicks in.

Final piece of the puzzle is now sitting in the back of my GC.
Tomorrow, I'm having my Corsa cat-back exhaust system installed. I'd be lying if I said I wasn't at least a little psyched!
Corsa Sport system seemed like the most quiet of the performance systems, while still sounding good and able to move those exhaust gasses out.
Not looking for major improvement in 0-60 times, but it's all about the little victories...1/4 second here, an 1/8th there and it all adds up. After all is finished I believe I'll have my 2013 Overland down from 8.3 seconds to 6.5 seconds. I think I can live with that.....I think.

Just got it installed and the sound is exactly what I wanted...Quiet until you put your foot into it. And then a nice note that sounds like the 5.7 should. I haven't had time to do any 0-60 runs yet, but I'll let you know how it goes.
My Overland is a 2013. I bought the system from Amazon. Their price was best and, to be honest, because I shop with them a lot, ordering was only one clickg.

Damn! After installation of the Corsa cat-back system, 0-60 times have RAISED to 7.4 seconds. There is a noticible sluggishness at launch and up to about 2000 rpm....where acceleration gets AMAZING. So it looks the Corsa system has thevsweet spot of my power band shifting to the top end.....Not really what I was expecting. ...or wanted!
I'll send an email with some data logs to Sean at HemiFever... Msybe he can do something....DAMN...I really thought this exhaust system was gonna get me down into the mid sixes....

Was your tune calibrated with the exhaust in mind.?I know my 2011 was noticeable when I installed it. The 2014 is harder to tell because the ZF8 does a great job off the line.

About to order one if these set-ups today and wanted to make sure that I'm getting the right exhaust. All I see is systems for the 6.4, is this what you guys ordered? Or did you get it from somewhere that actually said it was for the 5.7? Thanks

There are two different exhausts with different muffler designs.

I have a '14 Summit 5.7l. I live 10 miles from Corsa HQ/factory and get my cat-back system installed Weds 1/8. It is a one-off for now as the Summit has the squarish exhaust tip cutout in bumper. They are doing a custom post muffler and double tip (larger than normal) to fill the square cutout better. Since they also just purchased Volant they are installing a new Corsa/Volant cool air intake that is totally closed to interior heated engine air. It intakes only outside cooler air thru scoop.

CAN'T WAIT :drool:
