1. no rasp at all. though there is a huge magnaflow res. hiding under there where the stock one used to be.

2. i would love suspension, but i scrape enough as it is. boulder sucks

maybe someday though.
3. weight: hmm, not sure about that one. never got my hands on the stock mufflers. they took the stock system off in one big piece anyway. maybe someone else can step in, or if you want to look it up, its a 28" overall length magnaflow res. with two magnaflow 6" race body mufflers.
