Ya, it looks like the spot I'll do it is right after the Helmholtz chamber and before the 90deg bend going to the absorption chambers. I'll just have them pipe out the sides.. I have to look under the car to see if there is room there, but that would be the IDEAL place to dump. It likely will be much quieter than where others are dumping - pre muffler, but I want to retain some back pressure and the beneficial Helmholtz chamber effect. I'm just going for more sound here, not HP.
I bought a spare exhaust today..now there's no going back!
Man, I really wish I could find a real cut-away view. If anyone has a cut exhaust they are just going to throw out, why not butcher it for us!
