i wanna put in a down pipe, mid pipe and cat back but i dont want my cel light to come on is there any way to avoid it. or should i just go with the cat back..............

I haven't heard of too many people throwing a cel from a turboback. Most come from the uppipe. Most every turboback will either have a bung for the 02 sensor or a resistor fix. Not a real big problem. Just my .02

once you remove the cat after the turbo, you will throw a CEL. get a cel fix from gruppe-s.com

a cat-back will not cause you to throw a CEL

Its not worth the $ vs power gains to go with the cat back..Go with the full turbo back..1 high flow cat...cel fix...They don't always work..But..if your going to do it ..go for the turbo back.

if you get turbo back, you will get CEL from removing the "cats" on the downpipe, you can get cel fix from this website:

I just wanted to add, i got a cel after installing my turboback, even though i have the high flow cat. There are cel fixes though. I did the mechanical fix myself, but after getting rid of the cat inefficiency code, i got some other o2 sensor low voltage code, so maybe my rear o2 sensor is just f'd up.

Do a search fro cel fixes on i-club. You will see many threads. I had a CEL from my turbo back. WRXncrew hooked me up with a mechanical fix and i have no cel's now.I don't like messing with my factory harness some people do not care. Go with a turboback you won't be sorry.

when i got my helix downpipe it came with a cell fix and i have no cats and it hasnt thrown a cel
