Now that the suspension is pretty much done in the GTV, it's time to move on to the next step. Which will either be an exhaust system, carbruetors, or a brake upgrade. All in the 500 -/+ area. I pretty much know what I already want, except for the exhaust system. I want to get some opinions on exhaust systems, and what you think is the proper setup. I've been thinking performance headers, 1&4 - 2&3 all the way to the pipe. Then a straight 2 1/4" pipe all the way to the back and a rear muffler, to muffle down the noise. Also any recommendations & places to purchase headers and rear mufflers? I was thinking Ansa or Stinger, for a rear muffler.
