so i was wondering i can afford meganheaders right now but not the full catback exhaust i was wondering can i hoook up stock exhaust to the header? also whats the difference between 4-1and 4-2-1?

 

4-1 is from the manifold it starts off as 4 pipes than by the time u reach the downpipe its one
4-2-1 is from the manifold it starts off as 4 pipes than by the time u reach the begning of the downpipe its 2 pipes than by the time u reach to the end of the downpipe its 1 pipe.

sorry but if u look at the pic u will understand me better but tht the best way i can explain it

EDIT:: i forgot to answer ur question Yes u can hook up the headers to ur stock exhuast

 

An aftermarket header will absolutely, without a doubt, fit your stock exhaust system.

And 4-1 headers have 4 pipes that all merge into 1 pipe in the same spot. 4-2-1 headers have 4 pipes that merge into 2 larger pipes, and then those 2 pipes merge into 1 pipe. Generally, 4-2-1 headers provide bigger gains in the low-end, and 4-1 headers provide gains in the mid-range and top-end.

 

4-2-1 is what you want, you dont need 4-1 unless you're puttin out some major power, and yea totally go for the header on stock exhaust. Granted a header + catback will be a lot better, but it will definitely fit and you'll prolly see some gains too

 

thnaks guys! so you guys think i should go for the 4-2-1 headers? are there any 4-2-1 headers for a 02 ex?

 

yes, and yes

 

dude u have an Civic theresHundreds of aftermarket part available for it

 

sorry i feel stupid i meant to ask are there any 4-2-1 megan headers?
