Now what rid of 98% of my rasp with my GMMG was a 3" powerstick muffler.. And yes I have a FM merge as well
x2. A decent bullet muffler should take care of your problem.

I like that. How does the rear work? I see two mufflers, I assume there is another Y I can't see in the last shot. Do you have a video / sound clip of the car running and a few revs?

Thanks Torchd! That's exactly what I needed to hear. I like the sound of that system better with the bullet muffler in the I pipe better than without. The cutout is a nice option too. Hmmm...

Hmmm, IMO it sounds meaner like this compared to your other clip with the bullet muffler. I guess everyones taste in sound is different though.

Agreed. While playing the last two clips my first thought was "if that were mine I wouldn't make it round the block before I was going back to the garage to remedy whatever mistake I had made." I pretty well had that decided before you left the driveway. Adding the bullet made a night and day difference to me.

I have Pacesetter longtubes+TSP Off Road Y pipe+Hooker muffler...I hate the "rasp" around 2000-3000 rpm.

It also doesn't have that deep tone anymore it had with cats and a flowmaster muffler...some of you are saying a flowmaster merge will get rid of the rasp some of you are saying it won't so before I buy it what can I do to cut down the rasp and deepen the exhaust tone?

So you're saying it's a waste?
