Anyone have primary cats removed and no CEL on afterwards? How does the car sound differ after vs before?
What price does it come at money wise?
Contemplating, but not sure I want to touch, more growl would be nice, but not enough to be hearing it through the sound insulated cabin.
Thanks. Looking for choices and prices.

 

i have researched this topic, but have yet to make any purchases. i'm leaning towards 200 cell cats, but the following bypass pipes from FVD would likely be my choice for outright bypass pipes. i wish i could get 200s at this price!

I have FVD cat bypass pipes on my PTT. Much better sound and way less restriction plus the bonus turbo spool sound. No CEL as the car has a tune but for peace of mind I added primary 02 sensor extensions. Cat-less will sound great with factory mufflers and sport exhaust feature. ZERO drone while cruising.

 

curious what you do about emissions testing. love the 'whirl' sound you get when you de-cat/open up an exhaust on a turbo car.
i can't imagine it can pass emissions with the cat-delete.

 

With the tune it probably would pass any testing. There is no required testing in the states I live in.
