catless dp vs. catless exhaust
hi foks -
I am trying to move on to my next mod (already have JB+ and Helix FMIC). Would like to do both DP's and exhaust at some point in the near future. Trying to understand the benefits of going catless in either or both the DP's and exhaust. Its intriguing since the price difference is 300 per for catted. But I am not sure of the OBD (and sound) ramifications of going catless on both. At the same time tryiing to understand power dymamics of catless dp w/ catted exhuast vs catted dp w/ catless exhaust. While I am at it. WTF is an O2 sim? Does it mimic the o2 sensors somehow to fake the presence of a cat in a catless system? tia |
