HFC Z1 vs Motordyne
 

Thanks to the community I've made some good decision with my Z, so now I'm coming for one last question.

Currently running Z1 CAI and a Motordyne Shockwave. Car sounds amazing. I have a tune scheduled at the end of the month but before that I'm going to throw on some HFCs.

I decided against ART pipes after some consideration, so now the question is do I go with Z1 @ 400 usd or Motordyne to match the exhaust but 200 bucks more @ 600 usd?

I've searched a lot online and couldn't find anything comparing the two and very, very little review info on the MD ones in general.

Any help is appreciated.

I would do art pipes becase of the power gain If i were you, although I currently running z1 hfc I wished I got the art pipes

That was the answer I got from a lot of people but I need to pass inspection with them and I'm a little wary of the smell/sound.

The smell isnt bad my z1hfc have some smell to them too but the gains outweighs the cost for me, I would keep the stock cats whenever it's time for emission

I would go as close to the same cell count as stock whatever you do. It'll save you headache if you happen to not pass with a lower cell count later on. I personally would not want to be swapping HFC and stock cats every x amount of time just to pass inspections.
