    OBX headers with SLP LM2

    Is anyone running the OBX headers with SLP LM2 catback because I was thinking about getting the obx headers that come with the two fake cats and ORY. I currently have the slp LM2 catback and was wondering how the Y pipe fit up with the catback and what it sounded like.

    There shouldn't be an issue,I had to spread the pipe a little to get the OBX Y into the exhaust pipe.

    I used 2 dead blow rubber mallets to get it done,one to wack the other one into the pipe to spread it and it worked.

    Make sure you get the Corvette Bosch O2's they have a longer wire so you don't need extensions.

    Also get a set of burn proof wire sleeves from Summit for $42.00 to cover your new MSD wires,I burned a set up first thats how I know.

    Also get some longer bolts to pull the "O" ring gaskets tight on the bullets,you can re-use the OBX hardware but to pull the 2 halfs tight you will need longer bolts so you can catch the thread and pull it tight so the round gasket seats properly.
