Headers make the car louder plus if you removed the cats it would even be louder.

Should have done your YouTube homework. You can get a pretty close guess as to what it will sound like. What catback system you got?

Headers = higher air flow = louder.

To mute the sound a bit, make sure you have catalytic converters installed. The SLP exhaust is LOUD, so that will not help your issue at all. Most people recommend Magnaflow or Hooker catback for a more subtle sound. Do some research at www.ls1sounds.com for a lot of combinations of headers/cats(no cats)/catback. There or YouTube.

Yes, cats make a big difference in the sound. really cut back on the rasp.

Well looks like the cats have to go back on
