Should I kill the cats? So I picked up a Magnaflow catback and I have some LT headers that I want to throw on here shortly. I cannot decide if I should run cats or not.
My first priority is a good sounding exhaust. Don't want a ton of rasp or drone. I also do not want to smell like gas after a trip. I am running exhaust all the way out the back. I was thinking I could save a couple hundred bucks by killing the cats.
I am looking for a nice stainless y-pipe. (If anyone has any suggestions.) I like the mufflex set up but I want stainless.
I had also seen the GMMG thread about throwing the powerstick in the I-Pipe and I was also wondering if that would be a good subsitute for not running cats.
I'm a newb on the tech tip guys... lol Cut me some slack!!!

Kill em. Theres other ways to get rid of rasp.(good merge in the y-pipe/bullet in the I pipe.) And if the exhaust runs out the back, and doesnt leak bad, then you wont have to worry about the smell.
smell with a Y pipe to the end of the car is almost not noticeable. as for the cats, it depends. rasp can be removed as bluebird said but if you dont have emission issues then just save the money and go ory with bullet in the I pipe. you can always get a custom made Y that looks and fit awesome for a fair price. good luck 
I have 1 7/8" LT's, no cats, custom Y, back to a Magnaflow muffler. No drone, no rasp. Sounds rather nice, not too loud under casual throttle.....but sounds like pure evil when I get into it.

I would kill the cats if there are no emission issues. My headers have resonators that look like cats coming of both headers and then to magnaflow catback. No rasp. A cutout is recommended.
