I know you veterans on here are probably tired of talkin about this subject but i have a ?. I've had my VTX for 2 weeks, did the clayton mod on it, 6 holes in the back plate, of everything i've read i've seen nothin about drilling into the small center pipe, is this whats called goin deep? I like the sound the clayton mod has but i'd like it a little louder, I have a 12" long 1/2 inch bit that is long enough to reach inside this center pipe. Any suggestions or advice is much appreciated
