i am having severe backfire since i installed a custom 3" Exhaust on my r33
Series 2, it has also a Apexi filter and a Blitz Blow Off Valve. The 33 also stalls sometimes and i was told this is because of the Aftermarket BOV, and the majority of 33 do stall on ocassions!! Is this true!!!
Plzz someone help me resove the problem with the backfiring!!!! Wat can it be... ITs running stock boost and no other engine mods......
Cheers...
