Yeah, I am going to do some heavy sound deadening in the rear half of the car.One thing I noticed though, it seems to have quieted down a bit after I reset the ecu.The interior noise that is, when I'm keeping a continous speed.I swear it was louder before.

Also, I checked my 0-60 time and it looks to be about 1 sec faster now with the full exhaust. laugh.gif

 

Idk, ive had nothing but problems with my OBX 4-1 on my manual 01 with the OBX catback-- the o2 sensor bung didnt fit so alot of money later, i had it relocated-- problem is they put it 4" down and i get CEL after a week-- it runs rich and madtib, i think thats your problem also-- after a week or so, it will get back to LOUD and performace goes down from what i see but im getting a CEL, so i think replacing the o2 sensor may fix this problem-- or a SAF-C

 

I've never had any problems of loosing power with my header, I get CEL every 200 miles after reseting ecu, but I don't have a problem with that!

 

Go to zxtuner.com and buy one of the mil eliminators, works like a charm. I haven't had a CEL since I put mine in.

 

are all the mil eliminators universal?

 

Only problem with doing that is if you actually have a problem you won't know. If you have one O2 before and after the cat you shouldn't have any issues.
