- - Header question (https://www.ft86club.com/forums/showthread.php?t=30984)

Currently have ark catback and ark test pipe. Would getting a header throw a CEL? Is the primary cat or "was" where the test pipe is now? Sorry for the elementary Q.

Unless you get a catted header you will throw a cell. Most people delete the second cat without issues but the first cat (the one thats in the header) will be a problem.

Thanks to both of you for the replies. Well in that case, it's either a catted header orrrr some kind of compromise since my test pipe deleted the cat. any suggestions? I did read the first post via the link, BUT there was no result.

When Nameless releases their equal length chatted header, get that. A lot of us are holing out for it. Hopefully the production unit has the same gains, because it's looking awesome.

I think i saw on ft86speedfactory that hks has a catted el header.

Haven't seen the dyno numbers, but the primaries on the Nameless unit look a lot longer. FT86SpeedFactory gives amazing deals and has equally fantastic customer support, which is why it really hurts me to say wait for the Nameless unit. But just wait.

1) Nameless header (AFAIK) will be catless.

2) If you get a header and a tune, it won't matter that you have no Cats, the tune will take care of the CEL

3) There are O2 sensor spacers available that you can fit into the second O2 sensor and get rid of the CEL that way.

what kind of spacers are those?? where to buy? im goin nameless all the way catless header-3in test pipe-axle back non offset, 4 in mufflers

When an aftermarket high-flow catalytic converter is used on a late model car its common to see a CEL (Check Engine Light) come and go. This CEL is usually backed by a fault code that indicates a failed cat. If your new cat is NEW, how could it have failed? Behind the scenes, the factory ECU is comparing the readings from a pair of oxygen sensors to measure the effectiveness of the cat. When a high-flow cat is used the exhaust gases are able to pass by the cat at a much faster rate, disrupting the readings. Our o2 sensor spacer retracts the second oxygen sensor from the direct flow of gases, restoring the balance that the ECU requires when using a high-flow cat.

Our O2 Sensor Spacer is CNC machined from cold roll steel & grade 8.8 metric hardware. After assembly, our spacer undergoes a zinc dichromate plating process which protects the spacer from corrosion. Installation is plug & play. Simply thread in our spacer, thread in the rear o2 sensor, and lock the spacer at the desired angle.

Strictly for use with a 49 state legal aftermarket high-flow catalytic converter such as the Magnaflow catalytic converter used exclusively in our exhaust systems.
