Flowmaster American Thunder Leak

[GMcD]

I just installed a flowmaster and i am getting leaks at both outlets. I have re-adjusted the clamps several times and tightened the dog **** out of them, they still leak. Any suggestions?

The Flowmasters are notorious for sub par quality clamps if I recall. I would buy new clamps as well as some of that exhaust paste they sell. Take everything apart, if possible, put the paste on ends of muffler and tailpipes, slide back together, tighten up new clamps, you should be good.

i think you might be right about getting new clamps, but i don’t think its the clamps fault. I took some pictures of the backside of the outlets, and it looks like Flowmaster put a cut to allow the flange to separate when the rear tail pipes are inserted. To me, this cut goes too far back and the included clamps arent wide enough to squeeze the flange completely tight.

I just installed Flowmaster American Thunder on my 2016 RAM 1500 and I was wondering is it normal for the passenger side tail pipe to exhaust harder than the driver side exhaust, while idle?

This is why I took mine to Meineke and had them weld it in. They had to remove right rear tire to get in & weld the tops. $100 well spent.
