SS exhaust w/ manifold on '78 280?

[FastWoman]

Thanks, everyone!

Steve, if a Flowmaster can last me 10 years, that sounds like a strong contender!

From what I'm seeing, I think 2.5" is about the large end of what people are using on these cars. I think I'm reading/learning/hearing that smaller pipe, within reason, results in higher exhaust velocity and therefore better exhaust scavanging. This, in turn, results in more power at lower RPM. I suppose the benefits of a larger dia are seen more at WOT and high RPM, and depite my list name, I'm not really a WOT sort of person (anymore). So I'm thinking 2.5" might be a bit big for my purposes. Even so, it seems to be a rather standard size for exhaust.

Fixitman, what does your exhaust sound like, now that it's completed. I'm skeptical of the glass-pack design. Is it loud, mellow, raspy? Does it produce a drone sound at cruising? I might be interested in your tubing and fittings, but might be using another muffler. Care to PM me with your asking prices? I'd still need to find a local shop to put it all together.
