3" muffler's for performance

I am getting ready to do the exhaust on my 440 dart. It is a fairly mellow 440 for now but it likely to get meaner with time.

I am running 3" tubing. I need a good flowing muffler that sounds good. Picture a DD capable, but mainly toy car. I live away from people and don't drive in town much so a bit of noise is ok. I want to build for the future HP increase so flow is important.

It looks like the Hooker Mufflers flow about the best in the reasonable price range.

Any thoughts or ideas, recommendations, links?

I'd like to keep it under $70 per muffler.

Thanks, ROB
