no money for it atm... lolz
and might get a project car later down the track anyways...
its too messy to convert this car to manual... good daily..

[beeza]

Yeah,I'll be doing a engine + manual conversion sometime in the future.

[dahon]

yeh ill jus get another car and prefer to keep the sedan as my showy daily driver.. haha

[beeza]

Yeah that's the best way.If U do have to sell one down the track,sell the sedan,put the seats back in the hatch/track car and ya got a sick daily!

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?

yeah like i can feel low - mid range increase although i think my car is due for a tune, so i'll be taking it to toda on the weekend.

last time it was tuned was when the exhaust and vtec controller were installed..

[B147ch]

i'll probably go for a higher flowing cat also, so maybe i'll hold off on the tune.

if you're gonna get an xforce header, dont, its the exact same thing as the $17 ebay 4-2-1 headers i bought, same material (stainless steel), same inside diameter, same quality welds, same note, same power gain.

in fact, most 4-2-1 d series headers are the same. if you're gonna fork out $600 for headers, get a bisimoto 4-1 header, makes more power than a 4-2-1 setup, throughout the entire revrange.

hrmm have you got any results to support that?

i cant really come to understand that headers going for 500$ is exactly like ones that are 17$

i compared my ebay headers right next to xforce headers, exact same in every way.
here's an example of the ebay header http://cgi.ebay.com/ebaymotors/Heade...spagenameZWDVW and compare it to http://www.xforce.com.au/cars/view_car/19
if you look at most d series headers (even the hytech 4-2-1), they all use the exact same design, and thus, make the exact same power. only real difference is that the xforce ones will probably last a year longer than the ebay ones. heck, for $600, you're better off getting a whole header + 2.5inch stainless steel exhaust from ebay.
