Does anyone know if the exhaust System from a 99-00 Civic Si will fit a 2000 EX coupe? One of my friends totaled his Si, and asked me if i wanted to buy it. His giving it to me for about $50.

Is this a good duel? Oh, if the exhaust does fit what type of performance gain should i get, in term of HP?

Thanks!

Just get under the car and look at it. I've got a 2000 EX too, and from the few Si exhausts that I've seen, I think it should work. The question would be whether it will hook up with your stock exhaust manifold.

Everything should fit up in the correct places, but just take a took where it would bolt onto the cat and make sure its the same flange angle. Then you should be good to go

So, it should fit! And all i have to do is keep an eye on is the manifold and the cat, plus the flange angle. Am really worry about the manifold because my car has a turbo, with a custom made manifold. But the manifold was made to work with the stock exhaust system, so if the Si exhaust works with Ex stock manifold there shouldn't be any problems.

Well, Thanks Guys
