stilen hi flow cats

[nik..]

if i will install stilen hi flow cats with the oem exhaust does it fit perfect?and second am i gonna have a problem with L sensor & check light is gonna be on?

I think the hi-flow cats should fit ok on an oem exhaust. You will get a check engine light though. The way to fix that is to put a spacer between the O2 sensor and piping. If you do a little searching there should be some write-ups on it, suggesting how to space the O2 sensor.

do you know any other brand of hi flow cats without check engine flasing light problems?

[aris_unlimited]

From what I have gathered all brands of hi-flow cats will show a check engine light when installed. Because there is more exhaust gas getting to the O2 sensor then it is programmed to recieve.

Sorry to disagree.

I installed DC Sports headers, Megan Racing high flow cats and HKS true dual exhaust and got NO check engine lights.

The headers and high flow cats had O2 sensor supports and I used the OEM sensors.

hihg flow cats yield very little hp gain, 2-3, save you mony and get a cat back exhaust, you'll see whay more gain

I just put on Berk hi flow cats combined w/ HKS tru dual exahaust. Sounds amazing and no check engine light.
