I heard that if you open your gas tank and stick your butt against it and fill it with your natural gases after 6 bean burritos, it's supposed to add power to your fuel injectors and increase your acceleration drastically. Only draw back is that it sends a nasty smelly green smoke out your tailpipe. Both you and your car.

Sorry, Mike.... "Seat-o-the-pants" dyno doesn't count. Nor do guessing HP or MPG.
I'm not saying that these claims are not true, but without solid evidence, they are merely claims without merit.
You've claimed to have had your HHR on a dyno for the intake tests. You've played with a G-Tech, yet no real numbers??
Are you selling performance or hype?? 
Back it up, please?

Until we get some honest, independent test results, any claims are no more that hype or BS, as far as I'm concerned.

But at least they provide a dyno chart. 
Now if they would just provide sound samples.

Good news!... Borla has a 2.25" exhaust out for the Cobalt, so I decided to inquire about the HHR. They responded (!!!!! !!!!), unlike Gibson, stating they DO have something in the works and didn't know when it would be available.
Here's the bad... they don't have dyno #'s posted, nor sound clips, however they claim an increase in power (by PERCENT- think 5 - 7%). That's somewhere between 8 - 12hp for the 2.4L ( )... still seems a little hard for me to believe.
Another bad... we all know Borla parts are nice- stainless, mandrel bends, etc... but $800 for a CAT-BACK!>!>!>? That's $100 PER PONY!!!! A little too pricey for me .

True. That is why the IMCO is such a no-brainer mod. Get a deep, "Big engine' sound for cheap. You also ditch that "aluminum turtle" looking stock muffler & heat shield. Then you can still save your $$ for a cat-back later - hopefully by then the charts & clips will be out.
