I have an AT3030 in the mail coming to my house and am about ready to bust a nut waiting on it. I have a 2004 QC Hemi Sport. My question is about placement of the new muffler. Some people center it in the hole with short sticks of pipe on either side and some people put the muffler all the way at the back with a longer stick of pipe at the front. What, if any, are the benefits of each setup. Is the almighty "resonance" in the cab the reason? I can't beleive 8-12 inches would be that different. I plan on keeping the stock resonator if this helps with any responses. Thanks.
