Downpipes from ADM!!!
Is there anybody besides me that would like adm motorsports to built downpipes (test pipes that removes cats) like they do on the v8's????They are the same cats and removing them gives 30whp 30wtq for only 219.99$ which i think besides nitrous kit is the best bang for the buck available ...gives 90% of the power of the longtubes, removes 22 pounds , enhance the sound greatly, will get you better gaz mileage etc!!!!
Whos in? And i dont work for adm, im a simple enthusiast like you all |

Honestly though, I'd rather just pick up some high-flow ceramic core cats. The slight gain for test pipe vs. high flow cats is virtually negligible, but that way you aren't spewing rediculous amounts of toxins into the air when the engine goes into lean burn mode. - X

If you were to remove the cats, "getting the car tuned" would have to include "tuning out the lean burn mode" which wouldn't be possible with a piggy back system, and thats all that it looks like we'll have for a while (the cobalt SS guys haven't even been able to crack this box yet, and they've had ahold of it for a while now). So, its either high-flow cats or spit out huge amounts of NOx. Hopefully you don't have emissions testing. - X P.S. - And if you were to tune out the lean burn mode, it would absolutely cripple your gas mileage. Lean burn mode can account for a 25-30% improvement in gas mileage, so you're looking at an 8 mpg drop or so.
