I'm looking at putting a new muffler on my 2001 camaro z28. I'm debating on the Flowmaster 80 series, the Dynomax Ultra-Flo Welded and the Magnaflow. Please give advice or if you have any other suggestions please let me know. Thanks

 

A full 3" "catback" exhaust will provide more power gain than simply changing out the muffler.

 

My vote goes for the Flowmaster, but it's just my opinion. I think the Flowmaster has the best tone, the others might make 2-3 more horsepower but I'd rather have the Flowmaster sound.
