A K&N drop in air filter s a good idea.
You can cut off the muffler, on my Spirit when i first got it it I cut the muffler off and it was still quiet like this, prob because the Cat was original(120K miles)
Basically I would make sure everything is working correctly, meaning new plugs/wires, ect..
Try to get an Intercooler as they help alot, you can make some pipes and put it up front.
Then possibly get a Grainger valve to rasie the boost up to 14psi, you should notice a difference then
