(Solved) Catback Exhaust Leak

Insane435 · 09-26-2016, 08:40 PM

EDIT: Please see post below. Issue has been identified but no solution found.

Anyone know what is causing this or if it is normal? It sounds like its near the center of the car or more towards engine, but definitely underneath. Could this be the vacuum line for the valve? It makes the same noise regardless if the valve is open or closed. Help!

I was able to determine this is an exhaust leak. The noise i'm hearing is a muted burble escaping through the "hole". The shop is telling me the mid-pipe doesn't sit right with the down-pipe. I used to have bad drone and resonance but that is gone. Now i just have a noise at idle and on back fires.

I have a hard time believing the pipe doesnt fit right. This exact system was another car without issues. I guess Ill have to take it to a different shop now.

Finally this has been fixed. Just a poor install done by the first shop. I need the downpipe now because the catback is not loud enough!

+1 for DP! Lemme know if you end up going with Armytrix or ER/VRSF. Interested to know how the others fit the car, as I believe they have a better design than Armytrix. So sooner than later, going to replace it.
