whats do you all thing about the Nismo Cat-Back Exhaust?

 

Looks stock, sounds badass - but I've heard awesome things about the HKS Hi-Power too... And Stillen. I've searched the board, I found one person who totally vouched for Nismo's Cat-Back, one person who vouched for HKS's Hi-Power Cat-Back, and one person who vouched for the Stillen true dual Cat-Back...

 

go custom
2 1/2in piping and delete the cats. delete the resonators and put high performance tips to decrease rasp. 400-500 bucks and it will sound better than anything else.
