Replaced the stock system and cats around 50k miles for an ark grip and berk HFC’s, haven’t had the car on a lift since then which was about 1.5yrs/15k miles ago so I haven’t had the chance to inspect it thoroughly. There’s slight evidence of aging just looking at the mufflers, but nothing too noticeable. I live on the coast of NJ as well, so that’s not helping my case.



Does anyone have any experience with the life span of these systems specifically? I plan to hold onto the car for at least a few more years, the main goal is to determine if it’s worth holding onto the OEM.



Thanks a lot
