I've had HKS hi power true dual exhaust on my car for about 5 months now and I absolutely love it. Great sound and great HP gains, but I want to step up the sound...I want it too be louder at lower RPM's and obviously louder overall...anyones .02 is much appreciated, whether it be test pipes, straight pipes, or whatever...Thanks just lemme know

 

MD ART pipes hands down. Great design, beautiful look, proven power and sound. Only downside is the cost.

Exactly what I was going to suggest. You beat me to it. Good call, Blue.

And stop having your cat punch me. Keep it up and I'm gonna punch you when I meet you in Austin for Project 512.
