So my stock cat is rattling and I removed it and the catalytic core is loose and shakes, it also pulls CEL and I need two o2 spacers to clear it.

Im looking for something quiet and no drone, I know both Megan and invidia makes a test pipe, but I don't see much as for high flow cat other then companies like random technology or ultimate racing, and those go for like 300.

I have a j's racing dual fx70rs, and would pairing a test pipe with it be too drone or loud? Any idea if Megan or invidia is more resonated?

 

I have a stock one, less than 50k miles

 

i would go invida test pipe! they sound nice!

 

Berk HFC works well for me (if you need to keep the cat)

 

i got a berks hfc, j's racing tp, and oem if your interested lmk using the j's racing tp on my car now but the oem cat and the berks hfc is off my car.
