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.

Cats or bullets will stop the rasp.Or spring for duals otherwise you will have RASP.

I like how mine sounds with the stock exhaust, cutout, and no cats. But my favorite is my old setup I had on my Camaro with no cats,x-pipe, and 1-chamber Flowmasters

what exactly causes rasp???? Before I thought it was just no cats. but it sounds like it mike be becasue of the y-pipe.

I want a single cutout no cats with my LT but I really dont want to regret my decision

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 have bullets and when I had no cats it made no rasp, and it sounded awsome, but to each his own.

I have lt's, no cats, Ypipe, and a cutout and its LOUD and raspy, and pops when you let off the throttle!

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).

So with cat-less True Duals you will get almost/no rasp?

Yea, it's possible. My TD's I had on my Camaro had no rasp at all. Just really loud and deep.

With mine I had no rasp ie. 2.5inch xpipe duel exhaust/long tube headers, and twister mufflers

I loved the back fire from my stock Cat, LM, & Predator tune, before I got the LT's.

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
