Will a 00 SI exhaust bolt up to a 00 DX?

Heard that the cats are different lengths!!

Any help would be great before I waste my time, thanks

IIRC exhausts from 2 door to 2 door will bolt up, as with 4 door to 4 door

As far as I know the DX with the d16Y7 engine has the cat integrated into the exhaust manifold. So in terms of length they should be the same but the front of the exhaust will stop short of where the cat should be...

I know for a fact as I have both cars at the moment.
That doesn't mean you couldn't do it with some work though.

thanks for the info... what about a sedan exhaust?

Same deal on the sedan... If it's a D series engine the cat is connected to the ex. mani.
You could get a cheap header (for a D series) and then bolt in your 00 SI exhaust (incl the Si cat) to that header.. I THINK that would work but you would need to cut out some piping to make it fit.. Make sure you get a D series header though because D and B engines have different bolt patterns for the ex. mani.

Edit: if you wanted to take a sedan exhaust and fit it to your hatch you'd be in the same boat as the axle back back section would be too long for the hatch. Again, you may be able to make it fit by cutting out some piping.

This is the same thing that I was thinking. Alternatively he could just have a muffler shop make him a pipe from the stock manifold to the Si exhaust. That should be less than buying a header and an Si cat (if you don't already have one).

Sorry, I changed my post while you were comenting... see above.

Wait a second... the op has a DX right? in other words a sedan? if so then my bad, the original post was right... for some reason I though he had a cx hatch.
