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.

I don't think Sean did anything differently, but I did tell him I was planning on installing a cat back system. I'll log a couple of runs and send him the data. Maybe he can tweak something?

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.

Re: 2014 5.7 Corsa sound clip

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

Is that CAI the same as what Volant was selling before?

I suspect so as they bought them for their patents on closed box (true cool air intake) and low internal airflow restriction design. Won't know til I see it but I am expecting similar to part #161576 with the Donaldson PowerCore 4yr/100k filter. I hear there were some engine compartment brake line routing issues that they were addressing on the '14 5.7l when Corsa (TMG) bought them. They moved all Volant manufacturing and inventory to their Berea, OH HQ.

BTW, Corsa has a 6spd '08 C6 Vette test mule I may get as a loaner while they install mine....hehehehehe

I ask that because I bought a Volant CAI for my '13 Overland 5.7. The filter box is not really closed off to the engine compartment... I ended up changing back to my factory filter box with a K&N and using the Volant tube back to the T.B. This reduced my intake air temp significantly.
So I'm interested to see if Corsa is changing the design.
I also have a Corsa cat back system. The sound is pretty rumbky outside and no drone inside. You should be awsre that your 0-60 time will probably drop as the 3" pipes reduce low end torque. Over 2000 rpm though, the performance is great.

Re: 2014 5.7 Corsa sound clip

Interesting on the CAI not being closed off, I'll b all over it...thx

Regarding the 0-60, ya, not a focus of mine, would've got the SRT if it were, just having some fun with the new ride....get some good sound, upgrade from no warranty on factory exhaust to lifetime on the Corsa (I keep my cars 12-14 yrs) and doing it for basically free (sell the factory to some rock crawlers who crunch theirs to basically break even)...I also have the Billet Tech catch can and will get a ported throttle body and Diablo/Hemifever 89 tune...
