muffler backpressure

[panchovilla760]

well i just got a custom muffler 2.25 w/a obx adjustable muffler, since i have a b18a in my 91 hatchback. when i turn it on and its cold the muffler acts up. i dont know why its doing this but it has like a pattern when it starts u can hear the muffler let out air and then suck in air or something it only does this when its cold the it runs fine anyone know why it does this???

thats probablly just your engine setting in on its idle

it makes the exhaust sound a little weird.
