I don't know anything about the Bosal muffler, but a majority of the SE-R mailing list likes Dynomax Ultra-Flo mufflers. Pat Griffith (slowSER) raved about his Dynomax muffler when he replaced his leaky HKS muffler. I happen to have a Dynomax Ultra-Flo Welded muffer in my SE-R, and I like it. It's quiet but it seems to flow quite well.
When it comes down to it, though, most straight-through perforated mufflers will perform well. You can't go wrong with the likes of Dynomax, Borla, Edelbrock, etc. The next factor in deciding would be the amount of noise. I have a Borla muffer in my NX. It's not loud, but it's deep, and does not drone on the freeway.
In this case, it seems like you can't go wrong with either one... Though the Bosal will last longer due to its stainless steel construction. I say get the Dynomax Ultra-Flo Stainless Steel instead of the Welded model, and be done with it!
