HELP! Decisions between Resonated TP or Resonated HFC

Silly Rabbit

Not sure I follow you. If you bought a Cat Back Enhaust, it will replace everything past the stock cat. You won't need a y pipe or mid pipe, that is part of the cbe. The only other parts of the exhaust are the headers and the cat pipe. The test pipe or high flow cat will replace the stock cat, leaving with only the headers as stock.

I currently have the FI RHFC on my car. I don't have videos yet, but if you look for a thread titled Borla, you can see several videos of my exhaust with Borla CBE with stock coats and Borla CBE with ART pipes. I plan to put up similar videos with the RHFC so there will be a good comparison of all 3 systems soon.
