i was wondering if anyone thinks that that combination would be too loud for street use? also i have a injen cai, hks hi power exhaust, s-pipe with antifouler, and dc 4-2-1 headers and i have a check engine light on all the time anyone have any tips? thanks

 

It's abnoxious for street use... Taek had the HKS with header and intake and was super raspy...

RU sure you did the antifouler right, as it should kill that CEL... I've been CEL free for a year!

 

many people use antifouler and still deal with the CEL

i have I/H/s-pipe.
i tink tis PERFECT. its not loud, only loud when u at WOT. other than that, its basically stock with a little rumble (not noticable)

 

I installed my MMW header and Spipe today. Did the antifouler method with success. No CEL no nothing, sounds very nice. Need to get get a new mid-pipe with two resonators now.
