I have bong hole on my catback. Using DC sports downpipe with cat delete.
I'm keep getting rattle underneat the car due to o2 sensor.
I used 2 non-fouler so its long enough to touch the bot of car.
Are there place I can buy 90 degree bend o2 sensor?
Or can i just take off o2 sensor off my catback?
I did try to hammer bot of car but still get rattle.
Only place with 90 degree bend is on ebay and its 30 bucks. ripoff

 

which DP? the 1st DC had no 02 bung, the revised one has an 02 bung on the downpipe.
