Cutout question that everyone can answer!
Disclaimer: this doesn't apply to ungodly nasty track-only cars.
I went from TSP dumped duals to American racing 4" y-pipe, 4" DMH e-cutout, Magnaflow catback, and I'm much happier... Quieter than duals when closed, and nasty when open. Plus much better ground clearance. Duals with just Bullets are not reasonable for the street IMOP.
Good choice on the Flowmaster merge, and I highly recommend a DMH electric cutout.
The whole reason I got the cutout in the first place was that the previous owner had put a flowmaster muffler on the car. I gained right at 13hp and 15lb-ft on back to back dyno runs closed vs open. Hopfeully soon I will be going to something that flows a little better, but keep the cutout. Thinking about a Magnaflow or something along those lines.
Side note: My opinion may change when I do heads/cam...

I drive around with it open more than I do closed I think. I usually keep the car under 4k RPM's so its tolerable, but its not my daily so thats kinda the point

And the weight is pulling on my catback enough that its not quite centered under the car. I need to rig up a support for the midpipe.
