I've had my car for 3 years now and have had 4-5 setups. What came with the car was Stainless Turbo muffler (thrush?) welded in place with a cat and resonator (looked custom), then I had a fire so I opted to switch it all out. I got 2.5" pipes and 2 big glasspacks... that sucked. I removed one glasspack and put a high flow cat in. Still sucked. Then, I kept the cat, got smaller pipes and had another turbo muffler put on and it was nice but the muffler got dented so that's when I got my ss fartcan put in. It was loud and I was losing my hearing fast so I got a resonator put back on after the linkage. Now it sounds good but it's still too loud so I'm just going to ditch the fartcan and get a dynomax. It should sound sweet. Trial and error sucks. All that time and bs I could have just gotten a DC sports or Thermal R&D cat-back. Live and learn I guess...
