I do run with ArK hFC and ARK grip full exhausts with burnt tip. I hardly hear any hiss or I just grown to love that deep growling sound of the exhausts that I would care less about it.
Worth every penny IMO.
Btw i did have CEL with the HFC but that is why you need a good tune to solve that CEL.
Been running it for years no issues with CEL on.
