Keeping a 502 quiet with 3" duals....

I need to get my exhaust figured out so I can start driving this beast. All I have right now is the BB Swap Hooker headers which exit under the rockers on each side. Problem is, this car will need to be fairly quiet with maximum ground clearance. Car is not lowered. How quiet do you think it would be with dual 3" with dual Borla XR1's ? Or maybe do that with bullets before the XR1's?

I don't know how it will be with those mufflers, becasue I've never heard a car with them, but an H-pipe or X-pipe would help to reduce the sound level alot. Chambered exhaust would be something to look into... they can give you great ground clearance, and do muffle pretty well, depending on how "much" you use, but its not cheap.

go check out www.ls1sounds.com go on the left of the page and u will find 'true duals' click it and it'll give you just about every muffer/3" true dual combo u can imagine with sound clips and vids. pretty cool but i can tell u any bullet style muffler will not be quiet haha. I'm usually a borla fan but when i heard the xr1s i wasn't impressed. out of all the mufflers i liked the TSP muffler and the moroso spiral flow which i am most likely going to buy
