ok, so i got my DC sports headers fitted,

would it be a good idea to take the car to toda for some tuning?
considering the fact that it was tuned when i got the vtec cont. installed w/ exhaust?????

[B147ch]

is it a 1 wire or 4 wire type?

make sure you use the right kind of wires or you may end up getting ur engine light coming on

all good man.. just extended the wire to the bottom so reading all 4.. w00t..

You lose what's needed...I know Honda's like back pressure,so ya gotta get the right size piping and Header/muffler/hi-flow cat combo.What's your engine? and future plans?

Great to hear about the mudflaps

hmmm...

mines set up 2.25 cat back.. need a higher flowing cat w/ bigger inlet/outlet.
do you think i'm losing some potential power due to the fact that i put these new headers on???

Ok,a few questions:
What's a Vtec cont.?
What the outlet size on the headers?
What is the rest of the exhaust setup?

[B147ch]

apexi vtec & air flow controller.
outlet size is 2.25inch.. (need bush to fit to cat via flanges)
from cat back is 2.25 inches with hot dog resonator.

the guy said i need a higher flowing cat cos the one i got on now wasnt done "properly".

[beeza]

2.25" is the right size cat.You should match the cat size to the piping size.There's no way you would have lost power going from stock headers to aftermarket ones.I don't know about the controller,it sounds like it would be a good device for tuning but I wouldn't touch it after a tune.A tune is always good.Sounds like the cat needs to be welded or something.Is the cat ok or does it need changing?

[dahon]

well for me i just want stock piping with an exhaust to make it sound a little better. my engines a sohc vtec. so say a 2 1/4" outlet.
ive been getting mixed responses saying ill lose some backpressure etc, but considering my cat & headers would be stock it should still be alright aye.

[beeza]

Do U mean U just the muffler? if so I would go a 2",they can put a 3" tip on it for looks.

[dahon]

ahh kz sweet, cheers man
why just 2"?
2" twinloop? sounds good yeah?
time to save up agen.. hehehe

[beeza]

Your stock exhaust is 1 3/4"ish so you don't want to go bigger and mess up the flow.The twin loop is great,a really nice note with a good set up.Why don't yo want to do the header/piping?
