Well for under 200, it really depends on how much you shop will charge for labor. Because if you want to do the muffler delete and get new tips too, it might be 200 just at that. To reduce rasp, you're going to want to buy a resonated x-pipe (part number 11386) and put that in place of your stock h-pipe. That should take care of the rasp. But if you buy the x-pipe, get new tips and get it all installed, I'd imagine it'd be more than the 200 you're looking to spend unless you do it all yourself.
