Up for sale is a pair of the CNT Racing (ERZ Performance) High Flow Cats for the 370Z / G37.
I ran these 10K miles with no issues but swapped them out for test pipes when I installed my headers. These dyno'd 15hp over my stock cats. I did same day, before and after dyno pulls on a Dynojet
They are in excellent condition
I'm asking $220 + shipping. I'll cover paypal fees and the cost of insuring the package.
I have sold several items on here with no issues and have an ebay account for over 10 years with 100% feedback if you need a reference.
