    Spintech on the 6.2

    Traded my stock muffler back for a Spintech Super Pro Street 3.5".... Turns out, it's wayyyyy to loud. I dumped it for now, but this week it will be going to the exhaust shop to get some sort of tailpipe. I'm debating taking it straight out the back like stock, but may do a side exit in front of the rear tire. I haven't found a single tip I like though...

    Here's a few vids. It doesn't do it justice as to how loud it is. You can't hear people talking above 2200 RPM inside the cab.

    Yeah, Pacesetters, custom made Y with no cats. It's way too loud. I'll get a ticket the first time I drive it in town. The video really doesn't give a clue as to how loud it is.

    You don't have 3.5" exhaust I'm sure. I cruise at 70 at about 1800 RPM and its not TERRIBLE at cruise... like I said... anything over 2200 and its just too loud. I love loud.... but this is going to get me in trouble. It sounds amazing though. Very deep. I'm going to try a tailpipe before I add a resonator.

    It sounds amazing... deep is an understatement. But its just way too loud for a daily driver truck.
