It sound like you have done your research and know exactly what you want. :thumb:Miami Evo said:I am getting ready to upgrade the factory exhaust on my 2005 EVO MR. I have attempted to listen to as many sound clips that I could find on the web. The Perrin exhaust appears to have the best deepest and horsepower sound I found.... This is a very important upgrade and I do not want to have any regrets.
Even if it comes out totally wrong, just hang on to your stock exhaust, it's not a permanent alteration of your car. You'll definatly want to keep it anyway for "fix it" tickets or smog checks.
