I'm considering to install sport cat's on my 350Z (building year 2006/06) with motor code VQ35. I did some research and as far as I discovered Invidia does not have sport cat's for my engine type. I only found sport cat's for the VQ35HR engine. I found other brands like Japspeed and Cobra who supplies sport cat's for VQ35 motor code.

I would like to know what experiences you have with sport cat's and which brand you would advice.

 

No clue if you mean test pipes or high flow cats. If you mean cats, Berk is a good choice.

 

I like the Z1 cats, but Berk, Stillen, AP, etc are good choices

 

Thx for answer. I mean high flow cats. As far as I understand test pipes has no cats which is not allowed because of CO2 rules in Holland.

 

I've had good results with Berk HFC's. I had them installed them at the beginning of the season and it changed the sound of the exhaust note and noticed the motor is more lively with much quicker response. I don't know if that translates into more power, but you can hear it (Roadster owners can relate).
