Hi all!

I really need help from the experts...

One of the srt6 coupes that I am considering for purchase has the following mods: wavetrac, johnson pump, mod shorty headers, dual CAI, code 3 pulley, and LET tune.

Would any of these mods:
(a) increase emissions and make the car fail the emissions test (I am in DC/VA which require emissions tests every 2 years - i assume the emissions requirements are fairly standard except maybe some states which have none or CA which appears to have the strictest); and

(b) require additional periodic maintenance (beyond what is listed in the SRT6 owner's manual).

Many thanks!
