Installed and sounds great. Don't do straight pipe to mufflers. Need resonators in between to remove drone

I installed this by removing everything from the stock muffler back. Installed the series 40 exactly where the original muffler was and had exit pipe turn out just in front of the rear tire. Unless you were in the throttle really hard, you couldnt tell if it was a V8 or the V6.
