It seems like theres a bang for buck thing going on here. Dont get me wrong, saving money is great, but is also dangerous. I would NEVER put a $250 catback on my car. Why? The welds will be rubbish and will crack. The materials will be rubbish and will discolour. The flanges wont line up properly and when you fit it to the car, it wont fit right. Guarantee it. And once the thing falls to pieces after a year, youre up for another one. Do it once, do it right. Use parts that have had years of R&D put into them, not one made from cheapo stainless in a warehouse in China. Theyre cheap for a reason. If youre not prepared to pay the money for a decent prefab like Buddy Club or Skunk2, go custom. If its just sound you want, get the resonators removed. Rob Bliss will only charge you 100-150 max.
