Hey guys - hopefully I'll be installing a Berk high flow cat in my 08 CR tomorrow. Any tips from those who have done the install? Advice or tidbits? Thanks!

 

The 06+ models are pretty prone to kicking off a CEL. If it does, add some anti-foulers(you can buy from autozone) and put that on to see if it helps.

 

my install went pretty textbook.

soak the bolts with PB blaster and remember to use shock, not gentle torque to get 'em lose without stripping.

i did use a special socket head to remove the O2 sensor, but it think you could have done it with just a crescent wrench.

i am sure you won't have any trouble with getting the cat out, but i know my 05 was a lot less prone to throwing a check engine light than your 08. good luck.

this was probably the best mod i have done to my car. really feels like free hp with no downside.

 

Have a hard rubber mallet on hand to knock free thr stock bolts. It would be pretty near impossible to force these bolts with a mere wrench.

 

Should I disconnect the battery during the install to "recalibrate" the ecu??

 

I would. It only takes a couple of seconds. Don't know if it really matters but the o2 sensor is hanging free for a few minutes and might throw a code after the install.

 

I didnt even think to disconnect mine when I installed my test pipe. I didn't leave the sensor hanging though. Once I took it out of the stock cat I went ahead and put it in the TP.

 

I can't remember weather I did or didn't. If Berk's install instructions don't mention it, I'm sure it's not important.

 

i can't see how much it would matter. the sensor is still out in the open whether it is in the test pipe or not. it is an ignition on item anyway, so as long as the car is off, it is off.

 

Super simple... Should take a total of 20 or so minutes.
