I purchase a Perrin cat back about a year ago and left it in the box. I am getting ready to blow the dust off of it and install it. However, I had a question. I thought I noticed a threaded bung on the tube, is this used for a censor that I need to remove from the original exhaust? Should I just buy a new one instead of moving the old? Any other install issues?

thx All...

 

the threaded bung is for the rear O2 sensor. You dont need to buy a new one just make sure you put anti-sieze on the threads before you reinstall the sensor, it will make life easier down the road if you ever decide to take it out again.

hope this helps

 

I just put my Perrin exaust on yesterday, I didnt have any problems at all. Fits great. If you are using the stock cat, you will have to remove the studs from the cat and use the bolts supplied.

 

how does it sound

 

Any performance gains noticed?

 

I have not put it on yet, I will post an update when I am finished. thx...

 

cool
