I was just wondering, my car seems to be running fine; but merging on to the freeway today, I shifted from 2nd to 3rd and a loud pop sound came from my exhaust. I have had this happen before, especially when I switched to a high flow cat, but never this loud. Anyone know what this is?

 

minor missfire?

I hope not,what causes back fire?

 

too much fuel?

 

if it don't happen all the time, i don't think its anything to worry about.. i had it happen 2-3 times after 2.5 exhaust install.. thats in 20K miles

 

mugen ecu doing this? If it keeps happening is there a possibility of damage?

 

yeah it does not happen too much, I was just concerned cause it was really loud this time.

 

backfire. what kiinda mods on your ride?

 

Mmmm backfire.. I shoot flames

 

your car look like the back of an F-16? Its time to bust out the hot dogs!

 

I hear the same thing sometimes with my R w/ only a catback. It should ok, just becareful if it starts doing it more than usual.
BTW, have you installed the exhaust yet lopey?

not yet tom, just saving up for the install, but everything turned out cool....what a drive! I was hauling *** the whole time, it still took me an hour both ways!

 

If you are running a mugen program ECU then its not a problem its a really rich ECU progam.
