I am buying my first chevy cobalt. Its nothing special like the ss. Sadly its the LT for now.. i am wondering if i do a muffler delete or just straight pipe the exhaust if i will get a really nice sound as well as some crackles (pops,backfire) without it sounding stupid. And yes i know backfires are suppose to mean bad things but thats why i put crackle and pop cause id just like it to sound like any other high performanced car with it. I will be putting a cold air intake as well if that will help.
