DNA MOTORING Factory Style Catalytic Converter Exhaust Pipe Compatible with 01-05 Civic EX GX, OEM-CONV-018

Very Great, Fit like a Glove, No Problems 👍

I purchased this for my 2008 Honda civic ex it fits perfectly perfect, the lower gasket fits very well and the upper gasket is a cheap gasket it fits but it could go bad quickly. The check engine light turned off after installing this cat highly recommend.

first of all the catalytic converter is a lot smaller than the OEM. The product arrived and the welding on the head flanged are out of tolerance it was warped on the mating surface on exhaust gasket there is a 0.88mm gap that is not supposed to be there. The included exhaust manifold gasket was not enough to close the gap. also due to me Trying to installing it, and close the gad the bolt stripped the treads on the cylinder head so I need to buy threads to see if I can repair the trashed cylinder head. yes its trash now The hardware is all wrong, The triangle hole (on) the heat shield for the top O2 sensor, doesn't allow easy installation or removal of the O2 sensor the socket doesn't fit to lineup the threads. the two nuts for the 10mm bolt for the heat shield where not welded like the OEM making it really difficult to install due to no access to the back. nothing is working and the springs are to long and different shape than the OEM. the spring bolts aren't the same length as there OEM Now I am here cannot get hold of customer support and without a car that should be on the road driving. Very upset.

It fits and does the job,my cars CEL went away. upon intial use, for the first 35 minutes it ran in the morning was white exhaust. this may also be due to my engine being open (but covered) for a day during rain and getting lots of humidity in the exhaust manifold and in the exhaust pipes too. the o2 bungs are welded and stand higher than oe but my o2's fit just barely without trimming exhaust covers.if you purchase this you should be smart enough to know you must use antiseize compound on all exhaust bolts and O2 sensors.The bolts it arrived with do not fit whatsoever, completely incorrect sizes. It comes with a fat gasket and it is best not the use the OE twin thin metal gasket unless you lap the converter flange surface first because, it has a texture instead of completely glass smooth like OE.replaced my OE cat with this due to a bad o2 sensor and it got welded stuck in the oe cat rendering it unuseable.*Update 02-19-25: CEL light is still off and no white smoke recurring after 3K miles since installing this Cat. with new O2 sensors. I'll update if something changes.

Works well, esy to install, 👌 fits CRV 👍

Will work for your accord or civic as well bolt right on with aftermarket exhaust systems and headers

Did not work on my honda accord 99 because someone had already welded one om to mine so i just sold the car like that. But i did install this on a 2007 honda element after mine got stolen. I had it welded on , and everything is working great! Great price even if you have to weld this on!

Throws a OBD 2 code once in a while. Small catalytic converter than the original.
