Hmmm, the part numbers would be different from a civic si to an EG6. And actually I have an exhaust on my EG from my 99 SI, but I had to cut it down to make it shorter. And it would also differ from the eg hatch to a coupe as well. Well, if you have it off the car, perhaps you could swing it by swerve one day and I can compare with an exhaust to fit an EG. If it’s close enough to fit well even with little modification (as long as I can keep it clean) I’ll take it.
