My 05 works perfect with a single crankshop and an MBRP can.
the pipe did work well was just finiky to tune was probably just the sledon my 07 with an 860 kit i run a dynaport y pipe and a single with a specialty can seems to work really well, on my 03 i ran a crankshop pipe it worked well but required more tuning than other pipes just my 2 cents
