Needing help selecting mufflers for my 68' LS1 - Highway Driving

[almcbri]

I searched but couldn't come up with anything exact. I have listened to hundreds of videos on youtube and muffler web sites.

What I am looking for is a muffler that will not require ear plugs when highway cruising. I am going to do my best to conceal the noise with insulation, but that only goes soo far. I want a good sounding muffler, but when I am in the car with my family on road trips, I want something that will not be soo loud that we don't have to scream back and forth. Is there anything out there that sounds good but levels out at higher speeds?

I like flowmaster, magnaflows, and borla but I just cant make a decision.

What brand and series would you recommend??

I am going with 2.5" pipes with X pipe and long tube headers.

Thank You
