Looking to put in a Cold air intake in my little spark as well as replaced the exhaust piping adding a magnaflow with tip.

my question is would i run into any smog issues down the line ?

i dont think i'll need the smog for a few years but down the line when i get the notice of smog required would the new pipe system, muffler and intake be an issue.

i got a buddy thats telling me that all the upgrades will actually help the engine since its not working as hard as it would with the stock system

Assuming you left the catalytic converter installed you would be unlikely to make a significant change to your emission quality. The legality of a such a modification depends on your local regulations. In California intakes need to be CARB certified or you will fail emissions prior to the actual test.

Cold Air Intakes (CAI) can offer a noticable (though mild) power boost and a reduction in throttle lag. They typically also increase intake noise. Most CAI systems draw cool air from low in the engine bay or in the fenders. Depending where exactly the intake is rerouted it may put to at enhanced risk of water locking the engine. Short RAM Intakes (SRI) are another option that has a much lower risk of sucking up water into the engine, but still increases airflow. Injen makes an SRI for the Spark (PN SP7080), but I don't dyno results.

The exhaust upgrades reduce back pressure which can have a noticeable effect on top end power (but again mild). The downside (depending who you are) is that the exhaust volume is increased.

Generally speaking, don't expect huge gains from bolt on parts. At 1.25l the Spark's Engine is modest, it would require forced induction to get significant gains in performance.

thanks for the response

What im looking for was to give the spark a bit better engine sound, give acceleration a bit of a boost, and not hit my MPG too bad... im at 28.3 right now

im also adding wheels to it and i know that will impact MPG ...

Elementalist covered it pretty well. In terms of actual smog/emission you won't be causing any effects unless you start messing with the converters.

As for legality

1. Depends if modifying your exhaust is legal in the first place
2. Depends if authorities even care in your area.

emmissions rules regarding mods

then emmissions rules and laws are not then same nation wide or state wide ,depends on the opinion and decesions of the testors or their bosses , some only care if you meet the tail pipe readings ok ,others are strict as to exact equipment on your engine or car , regardless ,if you even modify to help, emmissions they will reject the added unit revertingto old approved way even if emmissions are worse . so, it depends on your state and local,laws and the testors and their bosses . her in oregon we have some cities with emmission testing and some areas and cities without ,,we are free here in Klamath county and Klamath Falls no inspections at all , BUT you are still, under federal law not to remove any emmission eqpt ,,but who would catch you or even care with no tests ? you do haveto be careful about converter removal though. some dealers and shops will turn you in or refuse to work on a rig with it removed .
