Headers and Daily Driving Alright, I currently have edlebrock shorties on my z28 and as everyone in the LS1 world knows, longtubes are the way to go. Now I would love to step up to longtubes but a number of people tell me they make these cars more of a rattle trap then they already are. I could understand this not being an issue with a car that sees the track as hp gains far outweight the banging or code throwing. So my question is are longtube headers perfectly fine on a daily driven car? My camaro only has 25k on the clock and runs perfect with the few bolt ons it has the last thing I want to do is ruin that.

In my experience, they don't affect daily driving, except for the more cars you'll be beating at the red lights 
seriously, unless you go catless (I don't recommend it) you shouldn't get any rasp.
It could affect your emissions at smog time (depending on where you live) and I WOULD wrap insulating / thermal tape around wires and hose that will come in close contact to the LTs.

Completely fine. True duals really wake the rattles up in f-bodies; long tubes with a relatively quiet cat-back can be as quiet as stock during normal driving.
A good merge is more important than having cats in cutting rasp; cats can cut rasp, but they're more of a band-aid in that situation for a shitty y merge.

i didnt have any cabin rattles with my LT's and catted Y into borla cat-back, when i put the tsp true duals under there thats when i got the rattles, LT's can be really mellow sounding with the right catback and mid pipe, i also had no rasp to speak of with the tsp catted y pipe and the borla

Yes indeed you will. My buddy had pacesetter LT's with the LM1 and it literally sounded like a coffee can full of nails. Sounded mean idling though. Some people like the rasp though. He recently switched out his loudmouth for the powerflow conversion when he got his cam. The car sounds great now.

If you do decide to upgrade to Longtubes, you should definitely add a set of Prothane Poly's to your list of accessories. They can be a mother@#$%er to install, but well worth it for the results.
There are a ton of threads with all the info you'll need to get the job done. Just do a search.
Good luck, man.

Upgrade to a set of Poly Motor Mounts (or Solids) and that will eliminate the Y-pipe from banging.

We have LT headers and daily drive our 2000 TA. We have an off road y-pipe and magnaflow catback. It doesn't rattle. We have poly mounts for the motor and trans. We have an M6 car. I hope that helps. It also has 85,000 on the clock as well. Good luck.
