When you say "2 ft", are you talking about the length of pipe? That is minimal compared with the restriction in flow from the pipe to the exhaust tips. If you were racing this car, and $1,000s of dollars were on the line, yeah, it's worth smoothing out and evening out the pressure losses in the exhaust trains. But this is not the case, is it?
