I just finished my x-pipe to single chamber flows and flowmaster recommends 10" pipes after the mufflers. will it sound better with this pipe/tip? I was just going to end the exhaust at the mufflers.

 

You people in TN have it made with no inspection. If we got caught like that here, we'd be crusified. I think it would sound better with the pipe on instead of dumping under the car but you can try it without it and add it later. Then go back if it sounds better the first way.
