move bi*ch get out da way

Default ummm, backfire? what the...?

the past few days i have noticed this....if i accelerate hard in first or second (i.e. stomping on the pedal and almost hitting the revlimiter) i will get one or two small 'pops!' from the exaust. under normal accelaeration i dont get this.

i have a minnam intake and stromung exaust, and recentlly had the plugs and timing belt replaced. would the instalation of an S-AFC help out? ( i have one to put in just need to get to rallispec) thanks guys!

best i can tell ya is to try doing a search on 'backfire'

it's a standard issue occurrence w/an aftermarket exhaust... nothing it wrong with your car... basically the backfire/backpressure is always there... just muffled w/the stock exhaust, intake and resonator....

search and you will see you are not alone.

your car is just popping. happens on all imprezas because of it's bozer engine design. no worries. A backfire is very very loud. It's like a gun shot! The popping sound happens because you have unburned gas in the exhaust pipe and the heat just caused it to explode. No biggie. I really like it.
