Who Thinks Custom Intakes & Exhausts Improve Performance?
Ok there seems to be a disagreement over whether or not custom intakes and Exhausts improve the performance of your car! What does everyone think? I know larry says loose the weight. I agree but let's stick to custom intakes and custom exhausts. If you think they help how much help do you think they offer and What is the purpose of buying a custom intake and exhaust if they don't help?

Wow, started a whole new thread on the topic. I was following it in the other forum 
Personally, I think that you get very minimal gains when adding an exhaust and intake to a vehicle. I understand that they help the engine breathe easier helping to increase power, however, I don't think the gains are significant by any means.
My two previous cars had intakes on them, as well as exhaust, and while I didn't really feel any gains (I installed them at different times, then GIAC reflashed the ECU, and that has an increase in speed) I still put them on. I put both on not because of the "gains" they claimed and I failed to notice, but because they would run so hot down here in the heat and I was worried about overheating. As for exhaust, when I had that installed, it just made the cars sound meaner, I didn't really feel any gains whatsoever. Both intake and exhaust claimed a combination total gain of 5-6 hp at the crank. I'm not sure how much of that was true, but thats what the ones I installed claimed, from two companies, for two completely different vehicles.
With this said, I do not think adding and intake and exhaust will give you the ability to smoke everything else on the road. In fact, just today I spanked a new corvette with a custom exhaust and when the guy and I stopped at the gas station, he said he added the exhaust to make it sound mean (which it did), and when I asked what gains it produced, he said nill, he couldn't tell, it just made it sound mean.
Intakes and exhaust are mostly purchased for the sound, not for the "gains," of their purchased for cars that people plan on completely modifying with big turbo or superchargers.
This is just my opinion on the question you asked. I hope it doesn't offend anybody by any means, this is all in good spirit
