Sucking sound upon throttle after Magnaflow Catback install
Just installed a Magnaflow catback system. Now, there is a slight hesitation and sucking sound when sharply pressing the throttle. Other than that, the car seems to be running fine. Any thoughts as to what might be causing this?
Here's a video... [ame="https://www.youtube.com/watch?v=dNZl1N9Y_U0"]BRZ Sucking Sound after Magnaflow Exhaust Install - YouTube[/ame] |

Do you mean the initial "chug" inhaling sound when you hit the throttle?

Mine is stock and makes that noise. I also drove a Celica GTS and when we put a CAI on it, it REALLY made that sound. It sounded like one of those speedy loud flushing toilets.

Incidentally, I lucked into this Magnaflow catback today for $200. Dude took it off his BRZ and threw it on Craigslist. I snatched it up with the quickness.

I find I notice sounds more right after I do a mod to the car mostly just because I am paranoid and looking for something/anything..

I've never had a car make such a pronounced and percussive intake noise. I think I might have to sell the car now.
