Flowmasters. You want muscular and low go with the 40 series Delta.
I plan on doing the single in-dual out Flowmaster Delta. Off the headers I'll do 2-into-1 via 'Y' pipe, then out of the Flowmaster 2" duals all the way out.
If you're after the sound I think you after, then I don't recommend duals all the way out. Besides being more expensive there won't be any performance benefit for your mild/stock 292. Plus I've been told that if you don't have a balance pipe you get a very lumpy sound, kinda like a v8 with a bad valve.
Flowmaster Original Series will give you a throaty sound but it'll be rather harshly loud, in my opinion, and not as deep as the Deltas. If you go to the Flowmaster site (http://www.flowmastermufflers.com) they have sound bits that allows you to hear what their mufflers sound like on actual vehicle applications. Some of the sound clips give you a "driving by" sound, a revving up sound and an "interior" sound. Really cool!
