Replaced the OEM primary cats with the Flowmasters and got a high quality product for a very reasonable cost. Very happy with the end result.

Installed these on my Pontiac G8. The exterior sound is a nice rumble. not too loud, not too quiet.The interior noise "drone" is rather noticable but not too terrible and has a little vibration to it. Again, not terrible. Nothing a little sound dampener cant fix.

I've been using their products for several years and it works great. Keeps engine bays cooler, keeps the heat in the pipe. Easy to work with using stainless tie wraps and hose clamps. Just wish it were a little less expensive, but it does what it is supposed to do and thats awesome.
