no cats=bad sound??? my system im gona get is gona be LT's y-pipe cutout and a muffleer with no cats at all. I know open its gona sound raspy and loud as hell but with the cutout closed will the system still sound crapy???
your system will still sound like ****, because you have the flowmaster on. it is hurting you more than helping you. If you get a good catback then you wouldn't need the cutout. unless you wanted the sound.

A single Flowmaster 80 series crossflow muffler will rasp with no cats. Personally I don't think it sounds very good. Now, true duals using two Flowmasters will sound great with no cats.
I believe rasp is from "sharps" in the plumbing; something
creates unpleasant high frequencies and sharp edges in
the air stream is my pick. Like people say gutted cats make
rasp, but I dressed off all the sharp edges inside mine like
the assembly inserts, and they sound mellow (lust a bit of
boom at 2500 or so where they are resonating). Look inside
your Y merge and it probably looks like hemmorhoids - both
the TSP Y, and the Jet-Hot Y I have, have pieces of one
pipe sticking well into the other side's flow-trajectory.
Like a grass harp. Only decent looking Y is the QTP, that
I've seen.
Cats are mufflers for everything upstream. But you can run
clean plumbing without rasp. It's second-rate fitup for the
welding, that's the culprit IMO. Happy hours on end with
the die grinder up in there, to get it clean (if you can even
reach, or see).

I have LT's, cats, ORY, and LM now, and I think it sounds as good as any cat-free car I've heard so far. I have to pass emissions tests in VA, too. No more back firing, though
