just wanna check something here. to do a dx to ex exhaust/header conversion, i need an EX header, an EX resonater/downpipe, and an EX catback exhaust, and it should bolt right up, correct?

 

yes, or you could get the manifold and cat and have a shop modify your current setup.

 

what do you think would be cheaper? and would it be the same hp gains?

 

you'll have the same gains, and the price is up to you, it depends on what kinda deals you can find. sometimes, if buy them, you could just go ahead and purchase all new aftermarket parts (h/cat/e)

 

go aftermarket, get an EX header, and then either an EX exhaust and EX cat, or a DX exhaust, then have a universal cat welded somewhere in there

 

i wanna order all the stuff off megan racing, but the brokerage fees to get it across the border would probly be outrageous. i can get a header, down pipe, and driftspec catback for around 550 dollars US. which isnt bad, but there would probly be 200 dollers in brokerage fees which sucks. i wish i lived the US

 

well the header bolts up to the cat, which bolts onto the catback, what do you mean by downpipe?

 

the part that curves is the downpipe...

 

i dont think i've seen a header that didnt come with that....and usually a resonator is part of the catback, see htis bulge in hte middle of the piping? Thast the res

 

My thunder header didnt come with the downpipe when i did my conversion on my 04 LX.... had them bend a custom pipe... the money came in when the shop had to extend the wires to the upflow and downflow o2 sensor wires... took their sweet time on that and it cost a ton!
