    Question do i have to have headers to use an OR Y?

    i have a lm1 exhaust and have a blown out catalytic converter and was wonder if i could just get an ORY pipe and totally get rid of the cats even though i still have stock headers? will this be way to loud? and which ORY pipe would work for this too?

    Won't reach. The ORY's are usually meant for LT's unless you can find one meant for stock length but I doubt it. Before I got my exhaust the previous owner had the cats cut out and had pipe welded in place of them.

    Yes they sell orys for the stock manifolds. It's very loud with a loudmouth. Not a good sound imo. Check Thunder Racing (sponsor) they sell a Basanni ory for 2000 cars.

    Like mentioned already, Bassani makes an ORY for stock manifolds. If you pair up a Bassani ORY with LM1, be prepared, its extremely LOUD!
