That remains to be seen Todd, but from what I've seen so far, there are good gains to be had from simple mods. I've been too busy yet to do any serious testing against the stock saw I have here, but.....we've got all the GTG stuff cleaned up now. I'll be sending Reed his 462 back soon. Thankfully, I've got another 462 here that I'm going to be able to keep for about a year, and I'll be starting on my winter of weekend cutting soon. To me, that's the best testing, real working conditions. I'll be on the hunt for another asap, I like having a stock saw for back to back comparison. Taking the baffle completely out might not be the best idea. It's got a bazillion spot welds, and seems to be adding a lot of strength to the muffler shell. On taking the outlet back.....there really isn't enough material there to get it back to what we are used to seeing.
