Thanks.. You too.. Jamie

BTW.. You are correct cheaper is not always better.. Quality & purpose should be important concerns.. Price in a perfect world should be second..

I would guess that we could make more efficient power if the computer could have more info on what it going on with the motor. Almost like tuning on a dyno. It could get rid of a lean condition, or bad fuel. I don't know, maybe air flow, temp and knock sensors are enough.

And then if we could tune our own motors with the likes of HP Tuners or EFI-Live to make up for small changes such as exhaust instead of going with an across the board fuel pressure increase.


Very true....thats what I use on my chevy truck motor. Very interesting stuff you can tweek. I just dont want to get to the point where the motor begins to work for emissions. Although a properly running motor shouldnt trip any emission sensors.

Notice that the A/F ratio is much leaner with the headers. On the right bank at 4800 rpm, we've gone from 13.15 to 13.87. What happens if we just lean the engine with the stock manifolds?

Will This Exhaust Work On A 2004 31 Sonic With Corsa Silent Choice? Also The A/f Ratios On The Dyno Sheets Of 14 ++ Are Too Lean At Those Rpms!!! Looks Like A Ecm Flash Might Be Necessary With This Exhaust System......

From the graphs it looks like Eikert is the way to go.

Just to clarify, that lean condition is the result of only adding the exhaust. No ECM modifications were done. That lean condition is exactly what we've being talking about in this thread. The 3 pound fuel pressure increase brings that number back down to 13.5.

As previously stated, I find it amazing that no other exhaust company is suggesting the fuel pressure increase.

Anyways, we've done the testing and make the suggestion to do the fuel upgrade.

GRS Fast - The system is compatible with the Silent Choice System. BUT PLEASE NOTE: your engine will not require the fuel pressure upgrade. That change is only necessary on late model 496HO applications. The 2004 and earlier engines have a different computer program that is much richer than the later model engines. You can add the exhaust to your engine with no fuel modifications.
