Well if you were in Surfers Paradise Australia I'd be happy to take you for a run:-) Yes the cats are 300 CPI, so no strong fuel smell like other X-pipes with 100 CPSI cats .You will find Alex or Nick at Gintani a wealth of information and enormous help if you are in USA. A Gintani tune is also a must if you are doing an X-pipe, you will get more advantage of the power gains of the X-pipe with a tune. Nice thing about that is the cable will carry you from a cat delete to a supercharger ECU remapping and back to stock if you ever decide to sell.
