Just givin you an idea is all.

I don't know if lumpy is the right word, but it sounds ridiculously tough. It's got to back to the shop to sort out an intake backfiring issue, and fit a quieter muffler, but when I get it back you're more than welcome to come hear it, or if you want the before/after dyno sheet let me know.
