Does Anyone Know What The Differance Is Between Lx And Ex Headers And Cat Back? I Know Stock Lx Have The Cat In The Header. And The Ex Doesn't But, Whats The Difference In Aftermarket Ex And Lx Headers? Will An Ex Catback Work With Aftermarket Lx Headers. Someone Plz Explain Thanks.

i took this pic so you can see the difference between the OE manifolds, Ex on the left, Lx on the right, that little small round part is the cat on the LX manifold, with the ex you need a B pipe to connect to the cat.

I dont know. I have the same question because Im going to put an EX head on my LX/DX engine and I dont know if the ex header will work better than the lx/dx header.

I want to know about aftermarket headers.Between Ex and LX/DX.

Keep your LX exhaust setup.

If you are expecting gains with aftermarket boltons, dont waste your money.

You will need the complete EX exhaust. Manifold, Down Pipe, Catalytic Converter, Cat Back Exhaust. I think someone says there's an issue with mounting it, but if I looked at the parts right, the only "problem" is mounting the down pipe/cat which any muffler shop could do that for you.

What I think I will personally do (before an EX head swap) is just the manifold, down pipe, catalytic converter and do an aftermarket cat back. That should free up some ponies on the non vtec motor and when/if you do the head swap, you will already have the ex exhaust for it. granted you won't make the same horsepower but in my dx / vp, with the little weight loss in not having power equipment, it should make for an even match or driver's race.

where can i get ahold of a down pipe and a cat???
