yep same here except I have about 20,000 miles on my Berk cats and. The CEL is not really whats bothering me though, its just that some days I like the sound the berks give the nismo exhaust, and some days I don't..

but I think I'm being too picky.. so I think for now I'm fine with my berks

 

thanks, yeah i'm very happy with the tp's. nice not to see the CEL on. i dont like it. right now my z is garaged. gotta get her tuned now. i would def say go with gtm resonated tp. i like the looks and the sound. the install was a pain, but removed the steering linkage.

wow thats some miles you put on there. does your CEL come and go also?

 

well it was kind of interesting.. I didn't get a CEL until about 7,000 miles after getting them installed. I reset it and it came back on after about 400 miles of driving. I even stuffed my O2 sensors with steel wool, yet 400 miles later the darn thing showed up again..So one day I was like f*ck it and left it on..

 

thank you, im tired of the HR low 300's dynos with exhaust on wtfdyno, whoseyourmamadyno and every other obscure dyno that exists. dynojet ftw as a standard.

 

Fixed....

 

dyno's should only be used for delta's

sadly everyone uses them for bragging rights

 

that sucks man. i would say the same thing...lol

thanks, i dont care really about trying to get the highest hr #'s. i really love the way the care sounds and the way it drives. i cant wait to get it tuned for the first time and then take her out for a drive. i will do another dyno run after the tune. also im not trying to get 300+ hp, just want my car to run good till i go FI.

+1, too true im doing this to see a before and after tune
