Exhaust popping

[kans]

Hey guys i got a skunk2 mega power professionally installed 2 weeks ago ~ but since the installment some times when i accelerate or put my foot off the gas and then accelerate it makes popping noises. Is this normal or does my exhaust have a leak? It also pops some times on deceleration as well, Thank you ~ i also have to add that the popping is much more frequent after i filled up with 95 instead of the usual bp 98 this week.

IS the popping definetly coming from the muffler, or more from the engine bay?

How does the car idle? Do you have a check engine light?

I would start by checking for vacuum leaks by inspecting ALL hoses and also spark plugs for possible mis fire.

Backfire?

Is it a quiet popping or a loud backfire?

After installing a catback on my DA9 it occasionally "pops" when I shift or decelerate, nothing serious.

My old SSS used to backfire when changing, running too rich.

You might be running lean - does this acceleration popping happen on startup or once the engine's warm?

Popping on lift off is normal - it's your ECU cutting out the spark to combustion chamber and dumping the fuel into the exhaust. This kinda popping is good.

if it's running rich youll notice that over a short amount of time there is a lot of black dust on the exhaust and a little bit on rear bar


IF it's running rich you change o2 sensors or reset ecu.

Definitely coming from the muffler, car idles fine around 900. Will check spark plugs tomorrow
i think it might be running lean ~ the smell of petrol is strong, also loud back fire

then it is running rich, common when bolt on mods are installed without a tune

just about to say.

reset ECU is the easiest thing to do, and some times it will cure the problem.

to reset ECU,

or just to check the ECU for codes.

probably wrong but,

do you have a silencer? i had a cannon on an itr that would pop, but it had a silencer built into it. so the opening from the muffler was actually tiny even though the tip looked massive. the popping was from decel to accel. changing the exaust fixed it, though i never viewed it as a problem in the first place. so yeh, may be because of a silencer or the design of the exaust
