prolly if using mild steel extractor, i've been running hotbits SS extractor & stock mid & end muffler for 2 years now and still it sound like stock exhaust, stock muffler don't rely on fiber to muffle the noise, they use restriction, that's why they don't have any fiber inside

have you tried having some one constantly revving the engine all the way up to 7k rpm while u stand next to the stock muffler at the rear of the neo? usually the tin kosong sound will only come after 5k rpm and might be muffled if you're in the driving seat with doors closed but its quite apparent when ppl hear your drive past them.. and those restrictions are made with the stock headers and catcon in mind.. once they are gone and the engine is tuned/modded to perform harder, the stock restriction will not fully cope with the new exhaust load.. maybe your neo is quiet with that setup but i'm guessing you are the exception since ALL my neo friends that i know have at 1 point ran with just headers upgrade but in the end they either modded their mid or end section to eliminate the 'prangggg' exhaust note later..

come to think of it, i never rev my engine clove to 7K rpm, not even pass 6K rpm, usually my rpm is around 3 or 4 K only, that is prolly the reason why i din't notice any differnt from stock header
