Reduces drone
Great quality and reduces drone. I Purchased the 3 in in/out variant and welded it onto my turbo acura integra with a 3 inch turbo back exhaust. My exhaust sounds perfect and no drone while cruising.

Perfect if you are required to have a “muffler”.
Makes the tech man happy so I am happy. They don’t do hardly anything for noise control, but it’s on a race car so who cares.

Surprisingly good quality and perfect size
Very happy with these. They filled a size spec that i couldn't find shopping on summit and the build quality is quite nice. They even have a laser etching of which end is the inlet and a nice perfectly round slip fit connection. Welds were clearly done by a machine as uniform and smooth as they are. Purchased to look like catalytic converters and take the edge off an offroad exhaust system.

Good for the price
Exactly what it says, fit great after weld. No difference in performance but got rid of the annoying drone from my straight pipe
