Revworks UEL Headers

[Jyoung1996]

These headers (revworks uel) came with one O2 spacer and a new gasket. There are two cats in the stock header, if I just put one spacer in will I get a cel with no tune. Don't want to tune until I get my full exhaust mounted. Vehicle: 2013 Subaru BRZ Limited 2.0L. Also was I made aware that some stock turbo kits from Subaru,scion,Toyota, Lexus or similar vehicles will mount to my car with some modifications. If anyone has anything like that available let me know. Thanks any advice will help I don't want to buy another spacer if I don't need to

To at least answer the CEL question. First there is one cat in the header with an O2 bung on either side of it. The spacer is used on the downstream (secondary) O2 sensor. When switching to an uncatted header, a tune is realistically the only way to be sure the CEl will stay out. Even with an O2 spacer on the downstream O2 sensor, there isn't a 100% chance it will stay off. More spacers really wont help that.
As for the tune, catbacks and overpipes won't make much of a difference in the tune. A catless front pipe may make a small difference if you are using a professional dyno tune, but if you plan to use a flash tuner with off-the-shelf maps, anything past the header wont really require a new tune.
As for the turbo kits, I suggest reading in the Forced Induction section of the forum for a list of compatible turbo kits. I have never heard of stock turbo kits from other cars that fit our car. http://www.ft86club.com/forums/forumdisplay.php?f=78

Very helpful man, I will defiantly look into it. It was just something on the back of my mind, I've already got illegal tint and don't need a cel to make it even harder to get inspected. Thanks for the help
