since i'm just startin out i was wondering what brand cold air intake and exhaust system would b good for my 06 ex and how much more hp will i b gettin thanks

 

it all depends on the sound really the hp difference in brands is not the much it seems the most pop. is the AEM intake i have one and it sounds great. intake and exhaust i would say around 10-15 hp gain

 

aem and injen are top two cai companies for exhaust hks, skunkz, apexi check out jwhitney and ebay

 

Doubt it

 

Prolly w a header.
Intake and exhaust will add about 8-9hp. Header adds around 3-5hp but it depends on ur ride 2.

 

Install an intake first then get headers and exhaust at the same time...and you should see an increase on your hp, close to 20hp. Like the others said, depends on your ride. Try to get your ride as light as possible, and you will feel a little faster too.

 

no way in hell is IHE going to add 11-13 hp. not on a civic anyway.

 

AEM, Injen, maybe even ebay with K&N filter would be good for intake. magnaflow and megan racing are good exhausts if ur on a budget, good power gains and nice sound for pretty cheap.

 

hhmmm..... How bout this one??

 

y should i put headers and exhaust on at the same time y can i still put the exhaust on then go back for the headers
