Questions & Answers

• Will this work with a Tomei Cat Back Exhaust?

  Yes it will.

• Should this work with an ams downpipe or would I need to purchase a ets Downpipe?

  This will work with the AMS downpipe as well as any other downpipe that terminates in the stock location.

• Hi, just purchased the GESI. Is the cat their High output rates for 500whp, or is it their Ultra High Output rated for 800?

  We use the ultra high output option.

• Would the GESI HFC pair with your V3 exhaust?

  Yup!  We designed our GESI HFC to be a direct replacement, so it will work with any downpipe/catback combiniation that mimics the factory design.

• What are the difference between the 3 of them?

  The GESI version has a GESI High Flow Catalytic converter in it which is for emmisions.

  The regular catted version just has a 200 cell high flow catalytic converter.

  The Resonated option includes a 3″ bottle style resonator to help eliminate drone and offer a slight reduction in noise.

  The straight through option is just that. Straight through test pipe.

• Does this item come with a new gasket, or does it have to be purchased separately?

  Gaskets and everything you need to bolt it on the car.

• Would this pass in California emissions?

  These are not CARB approved.

• Hi there! Was wondering what the difference was exactly between your HFC and your GESI HFC. Thanks!

  Gesi claims to get the car through emissions testing while having no effect on flow at all. It is just a higher quality catalytic converter

• Does this Test Pipe work on a Mitsubishi Ralliart?

  Yes, this works on the Evo X and the Ralliart.
