ok.. here is the symptoms... when i start my car up in the morning... the engine warms up.. and then after that..my rpm is at around 500-800 rpm... then i start to hear this putt putt sound from my exhaust. i have only AEM cai and greddy evo exhaust. so i am wondering why does it make the putt putt sound? is there something wrong with the air fuel mixture? cuz i've resetted my ecu after i've installed the cai and exhaust.

sometimes, when i am driving fast and when i dont' shift fast enough... i also hear the putt putt sound from the exhaust as well. is that normal? or did i miss something?

You sound like you have an exhaust leak. You may want to take it to a muffler shop and have them check it out.

exhaust leak? could it be coming from the connection? maybe i should retorque the bolts down to spec. thanks.

Ya, and remember not to tighten one side of the exhaust flanges down all the way and then tighten the other.

You have to tighten one a bit, then the other. Alternate them until they're tight. See if that helps.

Is the "putt putt" sound louder than the exhaust? or is it the same sound,does your car hesitate when you here the sound?

tokyoracer

nope... it's a very quiet subtle sound. and no the car doesnt' hesitate... but feels like a little boost when i gun it... kinda like sound like the misfiring system of the lan evo in intial d.

tokyoracer

yup... that's how i did it the first time i installed it. i'll check again. thanks.
