Actually, I had an offroad h-pipe with welded in aftermarket cats. It was rusted a bit and I could never get the crossover to line up (supposedly the bassani comes in 3 sections so everything will be easy to install). The cats were disintegrating inside so I switched back to the stock 4 cat to pass emissions.
MAN!!
My car feels choked!! It idles cold so much better but she feels just.......like........slow! Plus those stockers are like 3x as heavy as the aftermarket stuff. It does make a difference to have open exhaust!
