Induction and exhaust are sciences, as is engine design in general. Intake and exhaust must be matched to what the engine can and needs for operation. The easiest way to put it, is that the most restrictive spot from where the air enters the engine (the air inlet) to the tailpipe, is your bottleneck. If your throttle body flows 500CFM, but your exhaust flows 1000CFM, you still can only flow 500CFM. Make sense? Additionally, if your engine won't support additional flow, at best you will gain nothing by increasing the flow. Generally anymore, the limiting factor is the camshaft, not the intake, exhaust, or even heads on the engine.
Overgeneralizing, if you have too large of an intake or exhaust, you "stall" airflow, induce turbulence, and hurt perfromance. This is even worse on the exhaust side (normally aspirated motor=not forced induction) as properly sized exhaust actually helps make power...too big and scavenging is reduced, which costs power. Large exhaust on those little motors is beynd stupid to anyone that knows anything about how motors operate. A 1.6L motor built nearly any way you can think of, is never going to be able to use a 2" exhaust, let alone 3" or more.
What part of "waste of money" don't you understand? Air in = air out, unless the valves and cam are changed as well, making the IN and OUT bigger, doesn't change anything but the weight of your wallet.
that is even a bigger waste of your money. either go full exhaust system or don't even bother wasting your money. the flow of exhaust is still going to be restricted by the smaller pipes up front. so it is point less.
Also pretty much useless, unless all you want to do is make more noise. Performance costs money. If you can't afford to spend what you really need, then don't waste money on half-measures.
Okay some people are saying a cold air intake by itself is pointless and useless i can understand that. What about an axle back exhaust (dont have money for a full catback) and a cold air intake together, would that make a little bit of difference? Basically i want a better performance and response than what the stock in my car is giving me right now on my 161 hp
Ps- I appreciate you answering my question
