sometimes it's not what you say, it's how you say it.

If you run a hi-flo cat, your muffler will be the biggest factor in sound. Like I said I have the magnaflow version with headers and the SLP catback system. The SLP muffler does nothing and I'm loud. Mfuller has the catco version with headers and I believe a borla muffler, and his sounds about right.
