4 dr and 4 cyl vtec cold air intake,gas saver performance chip,n1 muffler,anybody got any other ideas for f23a1 to make it louder and perform better but not to pricy??

 

dont buy a tb spacer. I would recommend a 2.25 inch exhaust from cat back also a ebay cat conveter will do but you have to get a o2 sensor welded in. OBX HEADER was great better then the damn no names on ebay. Personally i would save for a turbo setup or motor swap bolt ons wont give much power
