Need your guys opinion? Hi Flow cats or JIC Y Pipe?
 

I recently purchased Stillen exhaust dont get me wrong great exhaust but it i want it a little louder which way should I go? If Hi Flow cats what brand I was thinking Crawford but just need some opinions? THANKS

Sorry I just dont think the construction of the stillen y pipe is all that great? Anyone want to buy it. Only put 50 miles on it.

Start with the Cats, you can't go wrong.

high flow cats hands down.

fast intentions is my first choice. crawfords would be my second. i wouldnt get any other brand though.

HF CAts all the way...

Fast Intentions HFC for sure. Great gains, great sound, better bang for your buck and FI is a kick-*** company that'll take care of you better than any other company ever could

Guess you didn't get the Stillen True Dual exhaust.....

Don't need a Y-Pipe with that one....

Yeah if you want it to be louder get fast intentions HFC.

I got the true dual but my friend has a jic y pipe on his 350Z and he said its the only y pipe worth buying because it has some kind of flex joints or something.

I got a JIC Y pipe and test pipes...
it's loud.

Is there a big sound difference between the crawford and FI HFC?

go with Top Speed test pipes and Y-pipe.

all i have heard is good thing from fast intentions

hi-flow cats, you will notice a big change in sound at WOT
