I finally got my flowmaster on my car. I'm very pleased. I still only have 2 inch piping the stock exhaust manifold and both cats on it...but I'll probably empty out the cats this weekend and a longtube header will be in the near future. When i do the header I'll switch to 2 and a half inch piping. I'll get a sound clip soon if anyone is interested in what a single flowmaster sounds like on a stock N/A.
