weird noise from engine

**carl06GT** · 09-16-2009

i just put a 3in catless dp and a FWI on my car and not when in barely getting the the gas in low gears. its a fluttering sound.

small exhaust leak maybe? if its not leaking from any of the flanges it could be leaking from the flex. is it coming from under the car? mine leaks a little, i can really hear it when the engine is cold but mostly goes away after its warm.
i can also hear it if im next to a building or another car. let us know what you find!

its coming from the front of the car. i know i have a little bit of a leak on my dp that i havent welded shut but i know its not that

Lifter tick? Sounds like an exhaust leak to me.

im hoping that its just the exhaust leak

The small leak on your DP may have gotten bigger.

Could you isolate the sound a little better? Does it do this in neutral when you give it gas? If so go into the engine bay and rev the vehicle and try and isolate the noise.
