Civic LX 1.7L 4

The car became very LOUD, especially when accelerating, and I knew something was wrong. I kind of figured that it might be something to do with the exhaust system and it was diagnosed as being a cracked exhaust manifold. It seems like this is a common problem with Honda Civics and it has been so for many, many years. The people at Honda don't care enough about their customers to design a better, more durable, exhaust manifold.

I had the car repaired by a Honda dealer and I was told that the cost of getting a new manifold by an aftermarket company was $700 plus labor, or $1,000 for a new manifold from the original equipment manufacturer (OEM) which would be Honda. The dealer didn't have the OEM part in stock and it would have taken another day, so I went with $700 aftermarket manifold.

Even after installing the new manifold the car seems really LOUD, especially when accelerating. I took the car back to the dealer and they reinstalled the manifold and said that the manifold gasket was somewhat misaligned. But it still seems LOUD. I took it back a second time, and the dealer says that it is just the way it is, but I'm not sure I believe him.

I know that it is a Honda Civic and not a quiet luxury car like a Lexus, but I feel like I'm driving around in a hot rod and it is kind of embarrassing that the car is so noisy. I'm planning to take it to an independent garage (one of the ones recommended on this website) pretty soon to get a second opinion.

My exhaust manifold cracked at 100k miles. Honda should release an OEM part with a better design. This is quite expensive especially after just replacing the timing belt which ranges in the 500.00 dollars level. I wish they read how many people has complaint about this and do something about it. I bought my civic brand new and it has been a great car until now. I hope these are only big expenses I will run into. At 100k miles, I still think is a great car, but it's cetainly not perfect. Then again, what is?
