BERK or ERZ HFC
 

Trying to decide which one to go with any help would be appreciated also Money not an issue

I've had ERZs for over 8,000mi with no CEL (using the right angle extenders). They were about 2/3 the price of the Berks and are working great. So, that's my vote. If I was going to spend Berk money, I'd just buy Fast Intentions resonated HFCs instead.

I should have mentioned I have the stillen cbe on my 370

do the extenders come with the erz,s

ERZs here on my 2010 G37xS sedan. Worth every penny.

I'd send Nissan Generation on the boards a message regarding the o2 extenders. :)

ERZ here too no issues

ERZ definate no brainer! i wonder when thier exhasut is coming out

I ordered my ERZ HFC..waiting for install this weekend

I guess erz wins does anyone know if they will pass an emission test in nyc

Any hi flow cats should pass emissions tests.

Unless there's a visual inspection. In that case, no bueno.

I'd save my money and get the cheaper one.
I recommend Stillen High Flow Cats.
You won't be seeing huge gain differences with any hfc/tp.
