I have about $400 or so to spend on a stock SVT...

Should I:
Buy a Trubendz exhaust and used B&M
Go to a local exhaust shop and replace the res. with a Magnaflow and lose the rear mufflers/add some tips---Hopefully cheaper than Trubendz, and I have fitment concerns.
Lowering springs
Try to find some cheap used wheels
Other (Please explaing)


Thanks!
