Cat delete

Will straight piping the catylic convertor give me an engine light? Im noticing a strong odor when accelerating hard and up hills. No engine light

Try switching gas first.

Modern cats flow a lot freer than days of old. Usually when a cat fails now it melts down and restricts exhaust flow and throws a code.

Its been an on going issue for a bit now. I thought maybe it would help airflow and sound better as well. I have no codes. Theres a big bridge near my house that i go on frequently and the smell comes when accelerating up it
