I think your best bet is to go to www.ls1sounds.com and see if you see anything there.

i used to have it on my car with MAC headers and it is very deep and will cause a headache
i switched it out with a lm 1 resonator believe it or not
i still have cats so its not as loud, but still LOUD
it does not give me a headache though because it is not a deep sound
if u have shorties or have the stock headers and cats go with the lm 1, u will love it!

I've got shorties with LM2 stock cats and stock y-pipe. Yes it is a low deep rumble. The LM2 was designed to be that way. LM1 has gurgle and pops. LM1 is a bit raspy. LM2 was designed to eliminate the higher pitch rasp and gurgle pops. It does it effectively too. I have a vert so I could see it being too deep and low for the interior of a hardtop or T-top for some people. I have also had an LM1 and I do miss it at wide open throttle(WOT). However my neighbors really would hate me coming home at 11:30pm every nite after work. I live in a yuppy neighborhood and sometimes it sucks.

Ok I just got my Loudmouth II put on and it is really deep but not quite loud enough for me, if I bought the SLP Y-pipe would it make it louder or what?

How much are the high flow cats i dont have that much money to put out right now so thats why i was thinking to go with a new y-pipe?will the y pipe make me fail inspection?im not really worried about power gains right now I just want to make it sound better. cuz im getting a cam put in this summer.

Unfortunately high flow cats are expensive. Anywhere from $350-$500. You'll want to go with a reputable name brand too. Some manufacturers claim high flow but actually flow equal to or less than stock. With Lt's and a high flow cat system you should pass here in DFW. I've made up my mind to go with Kooks Lt's and Magnaflow high flow catted y-pipe. Total together will run me about $1,300. But you can get a Tsp setup with ceramic coated Pacesetter Lt's and high flow catted y-pipe for $700. That's a really nice bargain.

Also, a SLP high flow y-pipe will cost you about $199 new. Look for a used one for about half that if that is the route your going to take. Personally I'd save a bit more and go Lt's and high flow catted y-pipe. Then you'll prolly be happy you got a LM2 instead of LM1.

Yea I wish I could do that but i just dont have the money to buy Lt's right now.I need something cheap that will give me a little more power but also sound better thats why I was thinking of the Y-pipe. Im just gonna have to live with my shorties for a while then im gonna sell them and see how much I can get out of them.

How much of a power gain would i get with high flow cats? Would it be more than a Y-pipe?

Im probably gonna buy the high flow cats then but would that be a waste of money if I plan on buying LT's in the future, and will there be a sound difference with the cats thats what I really want?

Can I use the SLP Y-pipe with the LT's or will I have to buy a different one for them? cuz if im gonna have to buy a new Y-pipe I better get it out of the way now.
