    just fit a twin 3" xforce system to the car and noticed on a cold startup it pops and farts around, just doesnt sound right. it only lasts a few secs. my question is, is this normal? i can only think that due to the larger pipes it takes a sec or two for the oxy sensors to pick up. doesnt throw any errors or anything. or am i over reacting. haha
    cheers,

    I'd gather the exhaust is still warming up, 3" x2 is alot of flow remember

    Shouldn't make any difference. The size of the exhaust won't change how the car starts when cold. Are there any leaks?

    its fairly non existent, for a 3" system its actually fairly quiete too.

    abba fan - not sure of leaks, havent had it up on hoist to find out. could this be causing it? will see if i can get a clip of it

    yeh, its odd cause it only started doing it ONCE the system was fitted. kinda sounds like a miss, but only lasts for prob 4sec max.
