Alien Posted November 7, 2005 Share Posted November 7, 2005 Hey ppl since I had my JAP made 3 1/4 inch exhast system put back on after driving around with a stocky system for 2 weeks, I notice now massive backfire on every gear change, every time. I put on a XForce mildsteel 3" Hi Flow cat converter onto my current system (the 3 1/4 one), could this be y the backfire is so more common now, due to a shit cat converter?

carl h Posted November 7, 2005 Share Posted November 7, 2005 excessive backfiring may be due to improperly set timing, whip out a light and find out where it is.......

shmiddy Posted November 7, 2005 Share Posted November 7, 2005 i had posted up this problem a few weeks ago and alot of the guys said its cos it could be running rich and the unburnt fuel goes bang, hence backfire Link to comment https://www.sau.com.au/forums/topic/93867-backfire/#findComment-1695861 Share on other sites More sharing options...

AlexCim Posted November 10, 2005 Share Posted November 10, 2005 Get your car tuned RB's run conservative tunes from factory, mega rich. Best to just put out and get a powerFC. Or you can get a piggy back like a jaycar DFA or SAFC Link to comment https://www.sau.com.au/forums/topic/93867-backfire/#findComment-1703592 Share on other sites More sharing options...
