The usage of headers & test pipes allows one to remove all four catalytic converters. Order some vg33e ebay headers. The passenger side exhaust manifold stud holes may need boring out. The 3 long studs on each cylinder head must be replaced with short studs (14064-7b00a) and nuts 14094-31u00. Also use oem nissan metal gaskets ( ) The part numbers for the test pipes which replace the last 2 cats are walker 54338 and 53345.
