any one know how they would sound on a 98 gt? is it worth the money... I have slp lm1 currently

 

VERY LOUD!!!
And yes they are worth the money. You will notice a nice power gain.

 

yea and you could get electric cutouts and then you could run them open and then close them at the push of a button

 

That would be biatchin. Especially the electric headers. OMG

 

ha i dont know where you live but around here youd be on the road for about 2 mins before the cops pulled you over

 

Ive heard of guys doing that on camaros but no much of 4.6's it would be cool especially if you want to raise some hell. Today i installed LT's and i turned it on before i had everything to check for leaks and it sounded mean espeically with the cam

 

way toooooooo loud for me

 

You can't get away with it legally, its going to be the first cop that sees you pulling you over gaurneteed.

Not going to be worth much/anything with your car anyway, the NPI cars don't respond well to exhaust mods, and regardless you would probably make more power with a LT/midpipe/catback combo, which promotes scavinging.
