i have the spoon sports full exhaust system; 4-2-1 stainless header, oem jdm itr cat-converter, b-pipe, n1 silencer.

although i have a full jdm system, many others out there are running customized "usdm" systems that in some cases surpass the performance of many of the "jdm" systems.

my setup is not as expensive as the smsp system that bbasso and george describe. another high-end custom exhaust system manufacturer is hytech in irvine, ca.

yeah, like gk suggests, maybe post a budget you have. the sky's the limit with exhaust systems.
