I currently have a stock 305 with all the stock exhaust, except the muffler which was recently replaced. My exhaust manifolds connect via a Y-pipe to a single pipe, then into the cat, then a single pipe from the cat to the muffler, then dual pipes out of the muffler. This Spring I am going with a new 350 motor. I don't want to dump thousands into the exhaust, but I do want to build it right. This is also my daily driver in a major metro area (Dallas). I need to keep it as street legal as possible. I was looking at some basic headers (with AIR). Should I ditch the Y-pipe and single cat/muffler for dual cats and dual mufflers? If I do that, will I still be legal? Or should I still Y and get a better single cat/muffler combo? And what recommendations do you guys have for a daily driver/mild off-roader for headers (with AIR), cats, and mufflers that are reasonably priced but will give me some added power?
