I was wondering if would be worth it buying all these items for the 30-40 hp difference, the KKM intake ($95), pro flow 75mm MAF($220), SHO Shop 37mm secondary butterfly manifold($230), SHO Shop extrude honed intake manifold($350), SHO Shop 63mm T.B.($220) Bosal Catback($550) MSDS headers w/y pipe ($600), ..............................................i currently have a different setup that runs a 50 shot of nitrous, K&N open cone filter with a polished aluminum intake pipe, and i guess you would call a custom exhaust setup no resonator with a borla muffler, sounds pretty good, not to loud, and some weight reduction i ran a 14.19 1/4 mile after a long cooldown, i wonder if i install these items if i would benefit any further performance (i know i'll gain reliability but otherwise) please inform thanks.
