EX Exhaust question??
 

If i were to get a megan downpipe and a megan header.... and extended the o2 sensor... is that all i will need to complete the ex exhaust conversion??? (besides buying an EX exhaust Catback) please let me know.... thanks

wut else..???
then get an evo 2 .....

i dunno if the stock ex catback will bolt directly onto the end of the cat replacement on the megan downpipe. the downpipe may be too big and only fit an aftermarket exhaust. so that wouldnt be a ex conversion... and ex conversion would be buying the ex header and ex downpipe/cat... but it would be full exhaust... mind that full ILLEGAL exhaust becuase the megan downpipe cuts out the catalytic converter.
