So I've gone thru 3 n1 mufflers and a supposedly sick magnaflow that cost me well over 200. I leep blowing them out, my tunes a lil rich and my cat is prob gone, I don't run a after cat o2 sensor.
I have zzp long tube 3 inch and zzp 3inch dp to custom 3 inch exhaust.

I plan on buying a new one very soon. Any opinions would help. Thanks.
