Just curious if anyone has done any performance mods. Intake, exhaust, a chip? If so what did you do and did you notice it while driving. Any improvement in fuel economy?

chips are bogus.....unless your obdi....the odbii systems cant change much unless you get your factory ecu reprogrammed, or run a piggyback.....

intake, dont know if there is one for the new gen.....first gen has a weapon r, which i would purchase for my 05, if it werent $190....lol....laughable for an intake of mediocre quality.....

exhaust, again custom would be the route to go.....come spring time, ill be opening mine up....

also fuel economy will not increase from any of these mods...cept a tuned ECU.....but finding someone to tune a nox ecu would be difficult.....

Most newer vehicles (Nox and Terrain included) can't be "chipped" because cars no longer use chips. You could reprogram the ECU with an aftermarket device, but you have to be careful with such things....aftermarket companies don't do extensive testing for their new settings. You could put one of those straight intakes on the engine to get you a little more power...but those things are risky because they can take in water as well. Your best bet is a low restriction exhaust system...I plan to do that when then factory setup gets up there in age.

The new Camaro, Regal, Equinox and Terrain cant be tuned without having a serious chance of having your warranty voided. Previously, you could do it without the dealer knowing but with the new ECUs it actually tracks the amount of flashes done to the software. If your dealer suspects that your changes caused the fault, you are toast.

Now, I dont doubt that an intake would seriously help at least with some extra power. The stock stuff is pretty restrictive.

My take is that if you feel you have to mod or tune a car for better performance then maybe you should have just bought the car in the next category up.

Kind of like all those Dbags who do up a civic...just go up a notch to the accord coupe. By the time you spend all that extra mod/tune money on the civic the accord is much, much cheaper.

So, a modded/tuned up Equinox/Terrain or a stock SRX.....Same price at the end of the day by the time you add your mods...which one would you pick? I'm taking the SRX.

There is nothing wrong with doing a CAI/exhaust on a vehicle. A tad more power is never bad.

Heck, with $200 I just knocked off .6 seconds and gained 4 MPH in the 1/4 mile with my G8. Now Im running what a Camaro SS runs yet I got my car for $10k less than a Camaro and have a much more useful daily driver vehicle.

I guess if the cost is minimal why not but one things for sure the computers and systems on board these days make it difficult to do anything without GM knowing and voiding your warranty.

Some cars I don't think you can even change the radio anymore....certainly not on the Nox/Terrain

Anything you can recommend to a noob? I just want a little mod to make it look nice, nothing crazy.

I havent seen a CAI for the either engines. Im sure you can make one pretty easily honestly.

For the exhaust, any muffler that is chambered would sound HORRIBLE on the I4. They just sound pitiful. You can get cheap ones off ebay and get them welded up for cheap as well.

From what i have read, these direct injection engines run rich, so it would seem like a smart idea to even that mixture out and see what these engines can do with a more appropriate mixture.
