Allright, here's the question. I'd like to put a new exhaust on my '98. I'm looking at getting a flowmaster and have been talking to several shops and cant' get a straight answer to which setup is better. One place says to get a single in dual out and they'll put a "Y" pipe to make it a single in muffler. Another says to just get the dual in/dual out muffler. I will be converting it to a dual out the side. Naturally a true dual would be preferable, but I don't want to spring for 2 mufflers and it is still a family car so I'm trying to get just a little more "man" out of it. The price is about the same for each. Is the difference between the two so insignificant that it doesn't matter which one I go with.
