    Remove 2nd Set of Cats?

    Just a question for the board in regards to a 987S exhaust. These cars have 4 cats in the exhaust system, what would the disadvantage be of removing the second set of cats? I see a lot of after market tuners are either making their own systems minus cats or taking stock mufflers cutting them, gutting and re-welding them and selling them for $2000+ as an after market item. Any one have some insight to this?

    Thanks in advance

    Re: Remove 2nd Set of Cats?

    I built a custom exhaust for my 928 and I wish I had a video so you could hear how great it sounds.

    Even though my particular model of 928 was never intended to have converters I included them in the new exhaust. Get some hi-flow SS cats with spiral internal design. They do not hamper sound or performance and make your exhaust clean.

    So on your boxster replace all 4 with 2 hi-flow's and put on an aftermarket muffler that you think sounds good. Sound is about the only reason to spend the time and effort.

    928's sound awsome. I bought a GTS in 1994. Loved the car and regret selling it. I also tweaked the exhaust system. That car sang to me man. 928 was/is the best sounding Porsche

    I enjoy it immensely and will not make the same mistake. So few nice ones left. So few period.
