Neither. Buy a electric car.
A cat back system made by Dynomax with Dynomax Ultra-Flow Welded stainless steel mufflers dill not "drone" the inside of the cab like Flowmasters do. Go to the dynomax website and listen to them.
i understand exactly where your coming from but if you go with a flowmaster super 10 you get the loudness of the glasspacks but the deep sound of the 40 series
I have a 1997 chevy 1500 z71 5.7 v8 and I was wondering which exhaust would sound the best a flowmaster super 40 or a flowmaster 80 series or dual cherry bomb glass packs.. I want it to sound loud but not to loud. I want to people to here me coming basically. and I want it to sound mean. (does this make sense) thanks in advance..
