Default Going the True Dual Way

Hey people. I bought a universal x-pipe setup from heddman headers today, along with 2 bullett mufflers (3'in/out) and turndowns to dump it before the rear axle. My question is, the car sounds too quite for me at idle, and the rasp from a y-pipe stinks. I have a tr224 561 112lsa cam in the car, along with hooker longtube headers, no cats, and my current cat back is a loudmouth. Will i finally hear more of that "LOPEY sound" from the cam with this x-pipe setup? and these dynomax bullett mufflers, are they good? Will i hear more of my cam through them? Also, will i notice any HP/TQ differance with this setup, or am i going to lose any HP/TQ? I'm running 2 1/2" pipeing. That should be plenty big enough.
Thanks

If you're not hearing anything with LT's, no cats and a loudmouth I don't think you're going to get there. Right now you have one of the loudest exhausts known to man, true duals isn't going to get you there.

You are better off changing cams to get more lope. The X-pipe is going to give you a more tame idle, and a slightly higher-pitched more racy topend sound.

Yes, you car will be loud with that set up. That's what I have now, the same cam & all. I now have it going out the back, but same sound, just redirected.

I'm going in another direction with the sound. Yes, I'm changing it again. First off, I love it loud, but want it loud when I want it loud, not all the time. I want to be able to hold a conversation, listen to the music, etc. In addition, I keep breaking the brackets off the back, that hold the bullets on. I assume this is when the engine tq's over on launching.

My solution is, to go back to dumping before the axle. I will keep the X setup, and put cutouts after the X, if I can, if not, then right after the headers.

I have chosen a muffler that is only 3.6" thick, with a 2.5" in & out, and only 7" wide. This should quiet the car right down. It should fit in there real nice. On down the road, I will add electronic cutouts, and consider a side exit, ala NASCAR. Something with a 1.5" opening, and however wide. Probably make it myself.

If you want loud, the true duals you have described will give you that, but will be a sweet loud, not a nasty loud, as in the loudmouth. As far as being loud at idle, you would have to change the cam as stated, if you do not get the sound you want. Good luck.
