2014 SUMMIT HEMI 5.7l…DO YOU WANT A CORSA CAT-BACK EXHAUST?

Many thanks to the team at Corsa Performance (TMG Performance Products) for working with me and agreeing to do this special run. This will use the current Product #14457 (3.0" Cat-Back, Dual Rear Exit with Single 4.0" Polished Pro-Series Tips) that fits the 2011-2014 Jeep Grand Cherokee 5.7L V8 MODIFIED with a different exit/bend out of the mufflers using 2 round tips per muffler staggered to better fit the rounded contour (see pics). Product # and ordering info TBD per below.

First, let me assure everyone I get zippo from this deal (I paid for my exhaust) I am just being the front man since I was first and live next to HQ. Please run all questions through me at this point. If you call Corsa, he will just direct you to me….thx

Looking to know who is willing to step forward and speak for one of the initial systems. I am looking for those who WILL BUY and those who are JUST INTERESTED. If you need to do research, decide, ect…then you are JUST INTERESTED which is great too. If you would be placing the order right now if you could then you are a WILL BUY. Just trying to see what the initial pool of buyers and prospects looks like so Corsa can decide the size of the first run.

To respond either reply to this thread or PM me. Either way, your spot on the WILL BUY list will be confirmed by return PM. To ensure the WILL BUYS get their systems the order info will only be sent by PM that way no one gets boned.

This is also posted on Jeep Forum Dot Com under the same title. I will combine the lists so please only reply on one forum.

Per Corsa…On a group buy of 10 the cost is $1597.50 each + shipping + ZERO TAX (In and out of Ohio). Once an order of 10 is ready to be placed it will take about 2 weeks lead time (Could be 3 pending work load in engineering/production at the time). It is a one box system that is about 98 lbs and some change, Shipping is expected to be around $75-105 flat depending on location, residential vs. business address, etc…The group buy would be run through one of Corsa’s nearby (Berea, OH) accounts to handle cc processing etc…The ordering contact info would be PM’d to the WILL BUY forum members.

As of 2/7/14 I have (7) WILL BUY folks. Those (7) should have a PM from me. Let’s see what the numbers look like through Sunday 2/16/14. Should have at least (10) by then. That would mean you could have it by St. Patty’s Day or so.

The Volant CAI is not included in this group buy. Pics below, videos to come in separate post.

FAQ’s:

EASE OF INSTALL? Corsa will install for FREE at their facility in Berea, OH (really!). Or go here: http://www.corsaperformance.com/medi...ll/INS5182.pdf

FLOW? Average of 97% gain over stock

WHAT’S IN THE BOX? Everything needed to complete the installation is included. Each system includes the mufflers, pipes, hangars, 304SS Polished Tips you choose and all of the necessary instructions and information for installation.

PERFORMANCE? Performance varies by the vehicle and system chosen. On average, CORSA systems will deliver a 3-5% increase in horsepower, though this may vary by vehicle. For example, our Corvette systems will see in average increase of 17-19 HP increases with the addition of our full cat-back system. In addition to HP increases, CORSA systems will dramatically increase free-air-flow, allowing your other performance modifications to achieve their full performance potential.

WEIGHT REDUCTION? 13 lbs. lighter than stock

DRONE? CORSA's Patented RSC® Technology is designed for an

AGGRESSIVE SOUND under acceleration and a DRONE-FREE EXPERIENCE

WARRANTY? Your current stock exhaust: None! Corsa: Limited LIFETIME warranty for as long as you own your vehicle with proof of purchase.

MY 2 CENTS? It sounds awesome when you want it to but is civil otherwise. It is the least droning system you can get, virtually zero except when MDS kicks in you get a little drone but it goes away. All exhaust mods affect an engine’s power delivery. The Corsa takes a small bit off your 0-60 times but really perks up your rolling “punch”. It has a really cool feedback snarl when you stomp it and the tranny shifts. Heads snap when I hit it. Pretty funny. Gas mileage impact? Well, never mind that’s not the point.

SYSTEM/PIPE DIAM/MATERIAL?
Stock, 2.5", galvanized
Corsa, 3.0", all 300 series stainless
Magnaflow, 2.5", 400 series stainless pipes, 300 tips
Flowmaster 2.5", 400 series stainless pipes, 300 tips
Gibson, 2.25", 400 series stainless pipes, 300 tips
Borla, 2.5", all 300 series stainless

SO WHAT? The reason most use 2.5 is not (according to their tech support) because it is better for backpressure/hp/torque but because the larger diameter creates too large a sound wave internally creating too aggressive a sounding exhaust and unacceptable interior noise (drone). This is the RSC patent Corsa has for noise cancelling to deal with the bigger sound waves from the larger pipe diameter. Regarding the 300 vs. 400 stainless composition. For the consumer 300 series is better. It has no (or very little) iron so it resists rust/corrosion the best but is more expensive to make and harder to bend. 400 series is best for the manufacturer. It is softer and easier to mandrel bend and cheaper. They mitigate it's surface rusting by using it in the undercarriage/non-visisble areas and use 300 in the visible tips and sometimes post/end muffler if visible. I guess the 400 series has more iron in it that when it goes thru its initial heat/tempering cycle in use the iron comes to the surface and forms surface only rust. Looks bad but supposedly will not rust out internally.

Interested in the same setup, do you feel any power increase?

For now, I am going to buy the CAI and wait for the exhaust to be released.

Like most aftermarket exhausts the power curve is adjusted. The higher flow actually nips a small bit off the bottom (0-60 went from 6.5 to 6.8) but gives more than it takes in the upper low and middle, top-end who knows (too afraid of a ticket) It has noticeably more power/pep from a rolling start like hitting it on the freeway onramp, OMG fun!

This thing has a cool gurgle/rumble at idle/rev, is stock silent at cruise (zero drone except for ocassional slight drone when MDS kicks in) and sounds like a modded motor when you stand on it. It WILL turn heads.

FYI, I will posting a "who's interested" call out for this exact system. Corsa will do a special production run if 10 say they are in. I'll add you to the list.

This sounds good, I am coming to Jeep from G35 and the main problem with it is not all aftermarket parts increase the power, especially CAI.

FYI I am living outside US, so I would like to know the price and the ability to ship internationally beforehand (so I would be in with 50% possibility), cause I can get Mopar (which is identical to Corsa) from my dealer, but I am waiting Corsa as I may save some money.

Can't imagine shipping being an issue (other than cost to you) but this will most likely never be a mopar available item due to volumes/demand. Corsa direct will do a special run of 10 and I don't think Mopar will productize and stock it at those low volumes. Could be wrong tho.

Do you have an estimate guess on how much corsa is pricing the summit catback?

Like stated, thanks. I am interested and ready to buy depending on price. I paid 1k for my corsa catback for my SVT raptor and it looks no wear near as complicated then the summit.I am guessing around $1500. Please let me know!
