even dc headers do very little. i forgot who said it, but the dc headers give about 10whp on a stock celi, but when combined with exhaust and intake they do very little.
Yea, I've been reading the threads about the headers... why is it that they give you 10whp stock, but when an intake and exhaust is added, it loses it's power? It makes no sense @.@
here's the thing. Our cars are tuned by toyota, for the existing Intake
, exaust and whatever. When you change something, the car cant tell, so the CPU opperates the same. You can spend a LOT of money on parts, but if you can't make them all don't work togeather properly, there's no point.. I'm leaving my car mostly stock for that reason. If I mod it, I'll go big and get a Turbo. There's very little you can really do - you're lucky to add 15hp.. unless you spend major coin that is...
