First sorry for the delay my isp provider wouldn't allow me to access this site. Now I replace the flex/resonator pipe. I simply purchased a cutting wheel for my dremel tool. The project took 5hrs. I simply grinded the studs off drilled them out to 5/16 then installed some stainless bolts. Now I notice that my car has a mild rumble that it didn't have before I replaced this part. I've checked for air leaks but couldn't find any. I think the resonator is generic and simply isn't designed for this engine. Thats were OEM honda is better. When I replace the muffler later on I will use a Honda OEM part.
