If you look under the car with the exhaust installed, you'll see why they did it. That driver's side undercarriage is tight.

I'd say if you want loud, ditch the factory mufflers for some Magnaflows. I tried 4 different mufflers on my 2004, and the Magnaflows had the deepest, richest sound. Since ARH is building a nearly full exhaust, I'd order the Magnaflows from Jeg's or Summit, have an exhaust shop install them and transfer the factory tips from the stock canisters to the MFs.

Headers/X-pipe/Magnaflows on an LSA should =

I can't wait until the videos start showing up with headers, x-pipe, and straight pipes on the 09V

Thanks for the hard work and bringing the headers to market so quickly.

I would be real interested in knowing the boost and HP with the headers, CAI, tune, and a new pulley.

That would be fairly cheap package that should put down some big numbers for $3K or less and not hurt drivability too much.

When this is 100% sorted and Jesse has a mailorder tune to match, count me in.

I wonder how long my auto tranny is going to last with an extra 100 HP?

Guys, Systems have been pre-ordered from Hennessey. I would contact them ASAP for pricing. We'll be initially working with Hennessey to help get these systems out to market. As some of you know Hennessey is well ahead of the curve with regards to performance packages for the new V and our systems compliment what they already offer really well.

Guys, These cars are very much like the Shelby GT500 that for a couple of years now have been getting the same packages; Headers, Cai, pulley and tune. They easily see 100 rwhp gains with hardly a change in drivability. This will be the case with the new CTS-V as well.

^ like someone said. The real question will be with the 6psd auto durability. 100hp extra is alot on a factory slushbox.

Thanks Nick! Guys we have systems on order with Nick. He expects to ship within the next few weeks. Below is the link to order the headers. We are honoring Nicks pricing on these awesome headers. We are also going to be using these headers on our packages instead of using the custom headers we have been building. Very similar to what we are building but we can save some fab time by just buying them. We will also package them with a combined discount with our Cold Air Intake than Nick used on his car. That will also be on our store within the hour.

You can pre-order a system and we will not charge your card until Nick is ready to ship.

Below is the link that combines the Cold Air Intake and the American Racing Headers.

Hey AR did you do these mods/dyno on a 6spd auto or a 6spd manual v2 ?

It should be pretty reliable. It's the same slush box as the 620hp ZR1. That's only about 30 over that mark and I am sure they expect slush box ZR1 owners to be modding also. It's a heavier car though I guess, but doesn't seem to far beyond what they probably designed this transmission to take. This particular slushbox model is ONLY in the most highly tuned cars and most likely to be upgraded cars GM has out. Think it's in the GXP also.

The OEM system has 4 cats, and 2 of the cats are eliminated in AR system it appears. In the OE system, are all of the cats monitored? And if they are, the AR system must be using simulators, (or equivalent), to prevent codes, etc., from happening. Is this going to cause emission testing problems in certain states?

RapidRod, What you think are secondary cats are actually resonators. The primary cats are monitored and that's it. I believe the trans can handle a great deal more than 100 additional hp. Fact is the trans in the G8's are handling almost 700RW in some supercharged applications I'm familiar with.

It's all about torque, not HP.

Umm...there's no such thing as an automatic ZR1. Not from the factory.

Razorecko · #30 (**permalink**) 03-12-09, 08:41 PM

^ yep. There is NO automatic for the ZR1. I've mentioned before that if the automatic was rugged enough to handle 620hp than they'd probaly have it in the new gen z06 and ZR1. Not only that but the 6spd auto would generate more heat than a 5 or 4 speed built auto. Time will tell but this is my consensus. If you plan on modding over 50-70hp+ you should get a manual.
