lots of poping sound...
hey guys
after installing my random tech cats, i've noticed an increase of poping sound coming out of my exhuast. I drive an AT so almost everytime i let go of the gas(after fairly hard drive), I can hear the pop. Is this something I should be worried about?
oh my power mods are
Ganz Intake
Borla Headers
Random Tech Cat
Cobb Catback
Cobb "Street" cams

are there any gaskets that you forgot to install with the cats? forgeting gaskets can lead to cold air entering the exhaust system and causing a "storm" with the hot air...thus the "pop" or backfire.

its typical with any kind of real exhaust mods. Subaru's do it naturally from the factory, just the stock piping usually supresses it a little. Adding things like headers, exhaust, high flow cat/track pipe, and especially cams will increase this "popping" sound.

I have a small leak between the cat and the mid pipe, since random tech cat pipe didn't come with a donut like the stock one, so the shop put 2 gaskets there. I guess thats why I hear it so much, since it doesn't seem like a big deal I wont worry about it as much.
thanks for all the responses.

I've heard that the pop might mean that your car (mine too) is running too lean. Someone suggested to me that some engine management would not only take away the pop, but add a few hp when it evens out the air/fuel ratio.
