since this question gets asked all the time, i will show the difference with some pictures.

as most of you know, the d16y7 engine that come with the 1996-00 civic dx's has the catalytic converter integrated with the exhaust manifold as one piece. on the other hand, all the other models including the d16y8 engine have an exhaust manifold as one piece itself followed with the 16.5 inch catalytic converter located under the car downstream of the exhaust manifold.

as a result, the stock B (or S bend) pipe on DX civics is 16.5 inches longer than the B pipe on the EX civics on the upstream side in order to compensate for the lack of a catalytic converter there. this is why when people with the d16y7 engine decide to order a catback exhaust while maintaining the stock exhaust manifold, they need to order a test pipe in order to fill in the gap. Or you guys just decide to order it and bitch at the company for making the B pipe too short.....



just sold the civic to my brother in law, so i thought i'd replace the exhaust for him since i wasn't running a muffler. manifold was cracked also so i replaced that too.

ran into trouble last night on install, stripped a nut. gave up for the night. this morning, we went to a buddy to borrow a dremel and cut the nut off, off to ace for replacement stud and we're done.

the infamous crack, white stuff is rightstuff gasket that melted off when i covered it as a temporary fix last year for emissions:



side by side comparison:





all done:

 

are those front fenders carbon fiber? nice.

 

Nice pics. I am sure some of them could be used for the 96-00 CX/DX/LX to EX/SI exhaust conversion sticky we have set-up.

 

nah, you give me too much credit lol, it's just spray paint with fading clear coat

 

ah, haha. I thought that seemed like a really random part to have on there, especially without a matching hood...
