Berk Technology high flow cat or MIL. Spec?
#17
I am also interested in a high flow cat, and everyone seems to be recommending the mil.spec 100 cell bolt on. I live in NY/NJ and my car has to pass inspection in NY every year. I've read that NY inspection consists of visual inspection and OBDII check. Will the mil.spec pass or should I go for a 200 cell HFC?

I have a Berk tech high flow cat. It's a great piece, and significantly reduced the noise of my exhaust from race car levels with a test pipe to neighborhood acceptable (I have an eBay downpipe and Greddy Ti catback too). I passed emissions in Nashville (Visual/OBDII) with it on, whatever that's worth. Also smells like fireworks when you go WOT now. No exhaust fume smell at any time since install. Welds are beautiful as stated before, and the outside of the cat will quickly turn a pretty deep blue/green from the heat anodization.
It's a nice piece and serves its function.

hey wj,
I have ran the milspec and passed emissions in va. They just test to see if the exhaust is being converted and the cat does its job. ONly cali is extreme when it comes to emissions but va you will pass no prob. You'd even pass with a dump since it's closed at idle. Only a testpipe will fail you here guaranteed

My mil spec has passed every time. No check engine,but then again I added a rear o2extender also.

ehhh ..
I ordered the milspec race cat after reading all the rave. When I first examined it I noticed the thing wasn't even straight, something looked off. I was disapointed when during install I realized the flanges probibly are not square and possibly not clocked correctly so the bolt holes dont line up. The thing is a pain in the *** to install and I can't get a good seal so I have some leaks at both flanges.
The thing didn't reduce the stinky exhaust smell as much as I hoped either, maybe reduced by about 25-30%.
As a comparison I also run a test pipe from Invidia. It fits perfectly. Its the quality I would expect.
Next time I have it off I am going to contact milspec and see if the quality is usually this poor or if I got a bad batch. For $300 I was expecteing a higher quality piece.

I read in another thread that I probably won't need an o2 extender if my performance mods aren't too crazy. Right now I only have a megan catback exhaust and short ram intake.
I'm thinking about getting a downpipe to go with it... maybe an o2/downpipe combo. Any recommendations?

Can you guys tell me around when you bought yours? I just ordered mine a week ago. I'll inspect it when it comes in and take pics if it looks different then it's supposed to.
