since i have a formula i dont have the dual cutouts in the rear bumper, i was thinking of just running a single 3" pipe out the back (off the y-pipe) and put a borla muffler tucked up under the bumper with a single dump coming out. That way itd be hidden, free flowing, and still sound decent. anyone try something like this before?

im wondering if it is worth it to do 4" all the way back?

With some internal work, probably. Bolt on only cars seem to do fine with single 3".

I have a single 4" from Y-pipe merge back with a single tip on the passenger side. I made it my self and and have no issues with the pipe hitting on anything and I ran the pipe over the top of the rear axle also.
