Okay... my friend Marius at Signature Performance had this to say
Perfect Power XMS: R5600 basic price with installation, go check out the Perfect Power site the ecu works with USB, freaking impressive shit
Boost Pipes for SX R1500 - cooler add another R2k or so...
The man also does stainless exhausts, 63mm, 76mm just what you want, with impressive tig welding, will give my X-Force a run for its money...
