Camaro L99 American Racing Headers (Catted) system with stock exhaust = +42rwhp
We dyno'd the SS last night after installing the American Racing (Catted) system with stock mufflers. For comparison, we used my BEST stock dyno run...I certainly "could" have picked my worst stock dyno to make the gains look better and if I were selling a product that probably would be smart, but I'm "keeping it real" so you know what it really did. (all numbers are SAE corrected, Same dyno for all pulls).
My best dyno stock was 321rwhp/332rwtq, by best with headers + tune was 350rwhp/370rwtq for gains of 29rwhp at peak/38rwtq at peak. At its maximum gain over stock it picked up 42rwhp @ like 5300rpm and 42rwtq @ like 4200 rpm. I will put some sounds clips up soon. It is as quiet as stock with the cruise set @ 80 mph, but it definitely wakes up at WOT. On my auto we didn't see the 50rwhp/45rwtq that was claimed (which I assume was on a 6sp manual car). However, if you figure dyno variation, weather differences between stock and modded pulls, and the different amount of power gained between manual and auto, I think my numbers are in-line with the advertised claims.

Well that should pick up your 1/4 mile times!!!
|
How much does something like this cost?
|
I'm not sure on the exact price but somewhere around $1850 + tune ($200-$400).
|
42 rwhp gain and you're still running the stock catback!
That's really good. I'm sure your car acts like a completely different animal now. Very nice. |

The axel back is the same on both M6 and A6...the difference is in the middle...their is a huge resonator on the A6 (to supress the sound of the AFM kicking in).
With TM gone from the Tranny and the headers on, it has certainly become a quicker ride. And now it sounds appropriate for what it is. |
Nice gains, I will be putting the ARH system on my L99 in the next week or 2, I will be real happy with the same increase in power.

I doubt it's even half that. We pulled the axleback off the G8 during testing and saw 3hp. You won't need a 3" catback till over 500rwhp |

Honestly I don't really know what's available yet the car is still so new that I have'nt seen an aftermarket system up close yet everyone is still scrambling to get parts out. Ultimately it will more than likely be a Borla system or something custom fabbed with our mufflers if it were my personal car.

I just ordered my Corsa Catback (ships Monday!), after I buy my Vararam CAI, ARH are next on my list! Does anyone sell them without the cats and if so how much?
