Hello. need advice.
1992 NSX. has comptech headers. always trouble getting it to smog california.
this time NOX high. shop says cats not hot enough.
shop suggests wrapping headers (which will keep gas hotter and therefore get cats to work)
my internet search on wrapping headers suggest wrapping headers can destroy the headers.
shop suggests also consider ceramic coating (which will be 1400 dollars).
what do you all think? the cats are 4 years old, after market.
Thank you.
1992 NSX comptech headers, koni shocks, later style rims, slammed
