ClarksHawk, did you mean the sharp change at 4900 rpm or the middle ish of the sliding trail off at 4700 or so as you said?

Strongjeff, I believe you were responding to the middle ish of the sliding trail off at 4700?

I guess what I 'm getting at is aren't the sharp changes at 2900 and 4900 shifts where you were "keeping" it in 3rd as you said you did in your pre-Corsa dynos?
***************

Okay, where it dropped off at 4900 and then spiked back up at 5000. No need to pretend to be smarter than everyone else.

They slow started the drive in 3rd and then pressed the accelerator down, jumping the curve. This way so it does not jump down to second or first gear.

Regardless of your love affair for Corsa, this is a shit exhaust system. It is WAY over priced and I feel you are getting some sort of kick back for your little group buy.

Huh? I was honestly just trying to clarify my understanding to better understand your question of "i need to figure out whats happening at 4700rpm" which I didn't understand based upon the dyno chart I was looking at.

Are you always this big of a d_ck to people who are trying to positively engage in your discussion?

Hey, there's a polite response to help someone understand. Way to go, try this more often.

Love affair? Huh? My comments in no way "bleed" Corsa. I admitted to my own let down and simply clarified for you what the Corsa IS not what you THOUGHT it should be. And sorry pal, 0.0 skin back to me. It's all hassle and just trying to help other Summit owners who want it.

As far as it being a sh_t system. Your experience is your experience and you are totally entitled to it.

Are you always in the habit of plunking down $1500 for a "performance" mod with so little research? It would have taken you 10 mins max to realize this was primarily for fun and sound. Proof is that Corsa does not give one single % or # value for HP or Torque gains. Yes, they talk it up but give no numbers. It's called MARKETING. If I were looking for % or # gains of a $1500 performance mod and the website gave none I would call the manufacturer and ask to speak to tech support and see what I could find out.

I love it when someone buys something, hates it for reason "A" and then b_tches and bad talks the manufacturer when it was never sold stating it provided benefit "A".

Oh, and BTW, your 50 ftlb torque gain from the CAI is completely bogus. An error somewhere someway. They just don't deliver that gain, PERIOD! I know one of the Volant engineers and he laughed. He said he only could dream of such a promise, oh the goldmine they would have on their hands!

You, my friend, and your useless thread have been officially "ignored", I despise dealing with amateurs who claim to be otherwise.
***************


Oh no ignored.. gee how am I going to sleep tonight.

Hey, numbers are there in print. If you have all these connections have your engineer contact me. I'll send him the files.

As far as me not doing research, I've done plenty on all 3 major systems. Also, being the founder of a vw & audi club in Colorado, and having friends and "engineers" in high places with companies like AWE, UNITRONIC, and GIAC, not to mention my connections and wholesale account with Adam's Polishes, borla, spec clutches and other german tuning companies, I know a few things about modifying a car.

Re: 2013 5.7L V8 GC TrailHawk and my Dyno run.

Finally, the reason I went with Corsa was the thought the system I purchased was in fact a 3" cat back. The build quality seemed great and the grade of stainless steel, and a comparable price seemed that this was the better system not only for quality, but for the non drone, the reliability and the exhaust note as well.

I didn't find many posts that actually showed any real numbers for power increases. So I took a gamble on this system. Heck even Corsa's own web site claims a power increase.

So, on quality and exhaust tone, I like the system. On cost and performance increase, I dislike the system... so much, I wish I never purchased it. I wish someone else had the ability to warn me. So im taking the time to show you my numbers, show you my video and give you my opinion. The numbers I posted are real and true. If you dislike them or disagree, I cannot help you.

ALL of those credentials and experience you have combined with ALL the research you did before you bought the Corsa AND given your stated expectations of X HP and Y Torque gains and you plunked down $1500 as your final decision?

Wow, I hope you improve the quality (read, NOT quantity) of your credentials, experience and research before your next spend....YIKES!

So the manufacturer states the below features and benefits and you decide this meets your HP/Torque increase goals? Scary, VERY scary!

Re: 2013 5.7L V8 GC TrailHawk and my Dyno run.

Also, in a previously mentioned post, the site originally said 3" cat back, to which I verified through AutoAnything. So, I thought I was also buying the ONLY 3" cat back system.. now, I see that I was lied to and misled to think I was buying something else of what I actually received. Thank you for your clarification. Now this 39 year old civil engineer can go to bed. Good night and stay classy

"Reliability"? If you did any research on this website at all you would have been very hesitant on this exact point. Tons of complaining about rattles from within the muffler, TONS. Only a passing reference was made to the current truth about that, it was a quality flaw in first run units.

"3 in."? Nope, sorry it didn't and doesn't.

"Heck even Corsa's own web site claims a power increase. "....this must have been right next to the 3" spec. They generically state this about their systems overall but make no # claims. Again, they say "power increase" and you make a $1500 decision on that when that is apparently your major buying spec? Scary, VERY Scary!
***************
Yes, and you facilitate a group buy.. taking money from people on this site. You should be very ashamed of yourself, taking money from these honest hard working jeep owners.

Put me down all you want, tell the world you think I made a bad choice on my purchase, confirm the lack of real numbers for the price. Thank you again for your support.

Re: 2013 5.7L V8 GC TrailHawk and my Dyno run.

And again, I'll refer to my previous conversation with Abraham at AutoAnything. He confirmed a 3" cat back. Not me.. and what makes you so sure that the website in March is what it is today? It said 3", now it says 2.5". Hey fool me once, shame on me...

I assume they do research better than you before they order their system FROM Corsa and PAY Corsa DIRECTLY.

I hope you do your Civil Engineer research far more competently than you do your performance mod researcy, crikey!

You are funny. I like you.

Also, since I'm the only one posting facts, I think my argument holds a bit more water than yours. Thank you.

WOW, you claim to have all this auto aftermarket hop-up experience. ANYONE who DOES knows that you NEVER EVER believe a reseller PERIOD. The very very first thing I do when I order from Autoanything or Amazon or Rockauto or Moparpartsonline or or or is VERIFY before I order. Hell, they said your Corsa fit a '14 Summit until I clued them in.

Besides, since you are so experienced you should know that 3", 2.5" it doesn't make a hill of beans difference in and of itself. What matters most with a Cat-Back system (no new headers or head work) are the choke points, resonators, mufflers, etc... That's actually the exact reason you don't get diddly unless you open up the heads and headers in one matched system.

You clued autoanything in on my purchase?

Fact 1: I was politely engaging in your discussion in a way to understand and also to provide understanding.

Fact 2: That came to a halt when you decided to be a d_ck!

Fact 3: You spent $1500 hoping to derive a specific benefit that you never specifically defined or verified prior to your purchase.

Fact 4: You now want to blame the manufacturer for #3

Fact 5: You are an example of how not to behave in a public DISCUSSION forum.

Fact 6: I am ashamed of myself for taking your loser bait and descending to your level.

Fact 7: I am done listing facts and done with this "discussion". I hope you (and Pleasedontfallapart) have learned what these forums are for and are NOT for. I have learned my lesson and will repent with changed behavior.

PLEASE DO BETTER RESEARCH

Either chrishawk has gone crazy and is talking to himself or some posts definitely got deleted.
