I recently purchased a 2004 Coupe with an awful exhaust system on it. I originally wanted a Fast Intentions but it is not in the budget right now. I found a never-used OEM exhaust that I bought to replace what is on the car now. My question is does the OEM exhaust use gaskets at each of the flanges in the system? If someone can let me know then it will save me (of very little mechanical knowledge) a lot of hassle when it goes on the car if the one I bought doesn't come with them.
