headers don't make your car loud at all. basically the design of headers allow better exhaust flow out of your car, which should give you better performance and increased top end. what would make your car louder is if you replaced your cat with a straight pipe or glass pack. headers are expensive though, and hoenstly i wouldn't waste my money there,

all the basic bolt on add up to a lot of money, you figure headers would cost like 350 then intake for another 250 then exhaust system for 5-600, that's almost a thousand dollars if not more. even for a 4 cylinder, with the gains you will recieve in numbers i don't think it's worth it. i'd look into saving for a turbo kit, supercharger or upgrade internals. i.e. cams, port polish, angle valve job, etc. but it's up to you.

yeah don't be an idiot like me and buy I/H/TP/E. get the nitrous first. then the rest.

or if you're going to go turbo, everything is going to be worthless. so plan first. i know i didn't.

You two have it all backwards. Did you mention to this poor guy that NOS and/or a turbocharger is absolutly aweful for your engine? Header, intake, and exhaust are a thousand times safer than both of those. And if you buy from comptech, not only will you gain good horsepower, but it won't negate any warranties.

Unless you beef up your internals and your overall engine, there is no way that a stock car can handle the strain from a turbo or even NOS. So here is my advice for people with a budget....

Anyone who wants power, go header, intake, and exhaust (thats a no brainer). If you want more power, go supercharger (NOT turbo...). If you still want more power, than I suggest you buy a faster car.

Nuff said

wait, you mean if I buy a comptech header and exhaust, my dealer will still honor my warranty? Is that written down somewhere, I've never heard that before? What is it that comptech does special to secure this kind of warranty support?

why's that? What's wrong with a turbo? Can't you get just as much performance, if not more, with a turbo? Or is it that comptech only makes superchargers, not turbos?

for the money being spent (270) you would be getting very little gains, on a dyno probably even 3-4 hp, but with a nice exhaust system maybe 6hp give or take. honestly that much hp isn't worth the money you are spending. but answering your question, no headers do not make your car loud.

as for comptech, granted their products are worth the money spent, beacuse on a dyno they actually show gains but as for warrenty covered by honda corp. anything comptech band is covered by whatever warrenty comptech gives because honda will not cover anything. the ONLY THING honda will warrenty is any spoon product. i.e. bbk, spoon suspension, etc. as for things that have a carb number on it depending on the dealer they will still keep warrenty to certain things. i.e. if you had an aem intake, and you have loss of compression in a piston chamber, warrenty will cover that, but if you have an aem cai intake and get hydrolocked then honda will not warrenty a new engine what so ever.....

as for aftermarket stuff, i agree with you that any form of forced induction isn't healthy for your engine unless you beef up internals. you can get away on stock internals with little amount of boost, your internals will be fine and you'll far exceed how much hp the basic bolt ons will achieve. but for that amount of significant hp increase, yes build up your engine, i'd suggest internal mods, raise compression, better fuel management, stroke, bore, then forced induction probably last, unless you want to build an engine based on forced induction.

turbo and sc and nitrous (NOS is a just a brand made by holly that got hyped by the movie fast and furious), sc is the most reliable route to go, you don't have to constantly check your oil etc like a turbo, but with a sc you are limited to an amount of hp by the size of the pully. and with a sc it takes power to produce power. but on the bright side comptech and jrsc are street legal

with a turbo, the unit is just using excess exhaust fumes. which are unwanted anyways. granted there is a lag, and you have to maintain readings, like oil, pressure, fuel, etc. it's a more complex system, but if in the hands of a person that knows what they are doing, a turbo charger is far superrior to all because of how much hp it can produce. downfall most turbo systems aren't street legal. ones that i do know of are greddy and now eddelbrock

as for nitrous, very simple, the best bang for the bucks. for about 600 bucks you can have a 50 single shot fogger into your intake and bam hp on demand and not as expensive. with a full system like a wet system, you can easily reach 150extra hp, but with nitrous of course it's illegal, but again you would have to build your internals, and most people worry about combustion, of something that will go wrong or your bottle exploding. but honestly working with nitrous, it is very easy to manage, only time it will combust is if the bottle gets punctured, just like any other pressurized bottle and if your lines have a leak. remember nitrous is just mere laughing gas, it's combustable with mixed with fuel (wet system). all in all nitrous is a nice little inexpensive toy to play with, but most people don't have the guts to.

just my .02 cents

even though the thread is about headers being loud or not....eh i was bored
