Flowmaster catback or dynomax bullet turn down? I have Mac Mid headers with mac y pipe no cats 2 and cutouts and its connected to Flowmasters 80 series crossflow exhaust. Should i keep this exhaust or should i cut it off at the I pipe and put on a dynomax bullet with a turndown? I want it to be louder than what is now with some decent back pressure and few more hp

Definately a Bullet turndown. That is what I have on my Pacesetter LTs and ORY. It sounds good, and flows better than a flowmaster

Despite there name....Flowmaster really isn't the.....well.......flowmaster
But my question is...if you have the flowmaster already, and cutouts..........why not just save the money that you would spend on the bullet setup and leave it how it is. The cutouts should make up for whatever performace you lose with the flowmaster, and easily make as much or more than a bullet muffler. Just run with the cutouts open!!

yes you are disturbing scavenging and air flow when the cut outs are closed, but you have the cut outs for performance, so who cares about closed cutout performance? FWIW you are gaining more with open cut outs over no cut outs than you are loosing with no cut outs over cut outs closed. Make sense?
