anybody experiencin really loud air flutter from high-flow cats? i had a set of kinetix ones installed a few weeks ago, and i get the sound during semi-aggressive acceleration and normal deceleration in gear.

 

i think you may have a leak

 

Ditto. Definitely a leak. Cheack and make sure the metal gaskets didn't get bent. Maybe the bolts didn't get torqued down enough. I fthat doesn't work call kinetix, I've heard their cats don't bolt on very well.

 

Make sure the o2 sensor is in tight..tHat happened to me..

 

f me in the goat ars.
