If are thinking about full exhaust, seriously think about long tubes.
Sure they are more expensive, but on a street car they make good power down low.
Plus they sound good.
My BBK ceramic shorties are already starting to get rust spots, after only 2 years!
And I think one of my cats on my BBK X is rattling.
Like everything else, you get what you pay for.
I would like to get new headers and mid pipe sometime. If I do, I will either do MAC, to go with the cat-back, or Bassani.
